DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a photographic processing method and a photographic processing apparatus. In particular, the present invention relates to a photographic processing method and a photographic processing apparatus capable of correcting a positional shift and writing image data on a photosensitive material when a photographic film meanders and a positional shift occurs when reading image data.

2. Description of the Related Art Conventionally, a photographic processing apparatus irradiates a latent image recorded on a photographic film or the like with light from a light source, and transmits the transmitted light to a photosensitive material via an optical system including a lens and a reflection mirror. It is configured to image and expose. In recent years,
2. Description of the Related Art A technique for performing color correction and the like using a color scanner (hereinafter, simply referred to as a “scanner”) and then performing digital exposure to obtain a color print or the like has become widespread.

In such a scanner, each pixel of a document having a color image is approximately classified into blue (B), green (G) and red (R).
Performs color separation of separating and measuring light into primary colors, reads out the intensity of each of B, G, and R light for each pixel as a color signal in order for each color, converts the color signal into a digital signal, and outputs relative intensity. This is an apparatus for producing a color print or the like after performing image processing as described later after converting into a value.
The device can be easily and arbitrarily subjected to color correction and the like, and can be stably mass-produced.

The principle of operation of such a scanner is that the original is wound around a cylinder and scanned with a spot light while rotating, the light transmitted through the color separation filter is converted into a photocurrent, and further converted into a digital signal to convert the photometric data into color signals. After expressing it as a signal,
Image processing such as color and gradation correction, noise removal, and correction of blurred or blurred images is performed by digital data processing, and the resulting output signal is converted back to light and spot-scanned and exposed on photosensitive material. To obtain a color print or the like.

In order to read image data, the photographic film is transported along a photographic film transport path (hereinafter, referred to as a "transport path") to a predetermined position at a predetermined image frame pitch so that the image frames are connected. It is sequentially exposed. At this time, in order to transport the photographic film along the transport path, film guides are provided on both sides of the transport path, and the photographic film is mechanically suppressed as much as possible by being guided by the film guide. Then, the sheet is conveyed such that the center line in the conveying direction is always kept constant.

[0006] The photographic film is conveyed by a conveying device having a pair of rollers or the like. According to such a conveying device, when the pair of rollers or the like nips the photographic film, the right and left of the holding strength are determined. It is surprisingly difficult to properly maintain the balance, and it is difficult to fundamentally solve the occurrence of meandering of the photographic film due to a one-sided effect.

[0007] The problem when such meandering occurs will be described below. FIG. 7 shows an original plate of a photographic film, and FIG. 8 is an explanatory view conceptually showing a state in which a scanner reads an image information ID out of image data while the image is misaligned due to meandering of the photographic film. It is. FIG.
8 and FIG. 8, image frames of a photographic film are schematically divided into a plurality of rectangular areas and shown as pixels, and reference numerals a, b, and
, c, d,..., in the width direction H, are denoted by reference numerals 1, 2, 3,... and are represented as coordinates, and are described as pixels X (d, 0).

Here, the scanner scans (scans) each pixel data in a direction H perpendicular to the transport direction T of the photographic film F and reads it in the image information ID area of a certain image frame. As can be understood from a comparison between FIGS. 7 and 8, in the illustrated example, among the pixel data, the D column of the scanning line has a displacement in the Hx direction, and the K column has a misalignment due to the meandering of the photographic film in the H direction. Awake.

At this time, since the scanner acquires the image data without recognizing the displacement of the image data, the pixel X (d, 0) and the pixel X (k,
The pixel data of 1) is lost, and the pixel X (d,
1) and pixel X (k, 0) contain false pixel data.

In order to prevent such a displacement of the photographic film F, a film guide G is provided so that a clearance ΔG is set between the film guide G (FIG. 7) and the photographic film F, and the clearance ΔG is provided. To 0.
It is set to a minimum value of about 2 to 0.3 mm so that the positional deviation of the photographic film F is hardly generated structurally, or
The photographic film F is biased by pressing the film edge, and the photographic film F is brought into sliding contact with one of the wall surfaces of the film guide G to mechanically (forcibly) correct the misalignment and convey the photographic film F.

[0011]

However, when the former clearance ΔG is set to the minimum value, the clearance ΔG is set to 0.1.
mm, the width of the photographic film F varies.
Moreover, since the width of the photographic film F expands and contracts due to the environmental temperature around the photographic processing apparatus, there is a problem that the same phenomenon as the meandering occurs.

On the other hand, in the latter method of applying pressurization, if the pressurization is small, the regulating force for improving the meandering of the photographic film cannot be obtained, and if the pressurization is large, the photographic film is mechanically damaged. There is a problem that may give. Furthermore, according to this method, there is a problem that a transport load related to the transport of the photographic film is generated, and a variation in feeding occurs. In addition, particularly in the case of simultaneous printing or the like, when the lapse of time after the development of the photographic film is short, there is also a problem that the photographic film is insufficient in hardness and is likely to be damaged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is intended to reduce the type (size) and width of a photographic film in which a positional deviation in the width direction such as meandering occurs during conveyance. It is an object of the present invention to provide a photographic processing method and a photographic processing apparatus which can correct a positional shift without damaging a photographic film and form original image data of the photographic film at an appropriate position irrespective of the variation of the photographic film.

[0014]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a photographic processing method according to a first aspect of the present invention is directed to a method for scanning and reading a photographic film F on which a photographic image is recorded. Photosensitive material 52 as exposure data
In the photographic processing method of forming an image by scanning and outputting the above, a predetermined entire scanning area S including the whole of the photographic film F in the width direction H is scanned and read in the width direction H, and the positional deviation in the width direction H is corrected. It is characterized in that it is determined, and the arrangement of the image data of the scanning row in which the positional deviation has occurred is corrected to be the exposure data.

According to the above-described structure, any kind of photographic film can be displaced in any width direction.
The arrangement of the image data can be corrected and the original image data can be written to the photosensitive material in an appropriate position.

According to the photographic processing method of the present invention, the photographic film is searched by searching a predetermined search range W of one end edge of the entire scanning area S along the transport direction T of the photographic film F. Since the position shift is determined by determining one end edge of F, the position shift can be reliably detected.

According to the photographic processing method of the third aspect of the present invention, a correct address is set to each pixel of the image data of the scan row in which the positional shift has occurred, and the obtained image data is overwritten. Since the displacement is corrected, the algorithm for correcting the arrangement of the image data is simple.

According to the photographic processing method of the fourth aspect of the present invention, the address of each pixel of the image data of the scanning row having the positional deviation is replaced with the acquired image data by adjusting the address to the correct address. Therefore, it is not necessary to set a new address.

According to the photographic processing method of the fifth aspect of the present invention, of the image data, one end edge of the entire scanning area S along the transport direction T of the photographic film F is close to the one end edge. Since the image data in the code area up to the edge of the image frame is skipped and the remaining data is used as exposure data, there is no need to store image data other than the image information portion.

According to the photographic processing method of the present invention, after the one edge of the photographic film F is determined, the other edge of the photographic film F is further determined to correct the positional deviation. Since the verification is performed, it is possible to detect a malfunction in correcting the arrangement of the image data.

A photographic processing apparatus according to a seventh aspect of the present invention comprises:
A scanning unit 54 for scanning and reading in the width direction H a predetermined entire scanning area S including the entire width of the photographic film F on which the photographic image is recorded, and digital image data storage means 53; , The width direction H of the photographic film F
When the positional deviation of the image data stored in the storage unit 53 is determined, an arithmetic processing unit 55 that performs an arithmetic processing on the data array of the scanning row in which the positional deviation of the image data has occurred and corrects the positional deviation. And an exposure unit 51 for scanning and outputting the image data as exposure data to the photosensitive material 52 for writing.

According to the above-described configuration, there is no need to provide a film guide or apply pressure to the photographic film. Further, the arrangement of the image data with respect to the positional deviation of the photographic film in the width direction can be corrected using the simple arithmetic processing means 55 and the storage means 53.

[0023]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1 FIG. 1 schematically shows the components of a photographic processing apparatus according to the present invention, and FIG. 2 conceptually shows the configuration of the photographic processing apparatus. The photographic processing device 1 according to the present invention includes:
As shown in FIG. 1 or FIG. 2, except that an image processing unit 50 (FIG. 2) described in detail below is provided, the configuration is the same as that of a conventionally known photographic processing apparatus. In this embodiment, a case where a negative film is used as a photographic film will be described.

That is, the photographic processing apparatus 1 according to the present invention comprises:
A development processing apparatus 61 that automatically performs various chemical or physical processes such as development with a developing solution Q or the like, fixing, washing with water, and drying with a heater H in a series of steps, To perform color separation in which each pixel of the color image of the negative film F is separated and measured approximately into three primary colors of B, G, and R, and to sequentially read out each light intensity for each pixel as a color signal for each color. A photo processing unit 60 including a color scanner device 62 and an operation unit 70 (FIG. 2).

After each color signal is converted into a digital signal, various image processing such as color correction and density correction are performed, and the processed image data is converted into a photosensitive material (hereinafter referred to as "paper"). Scanning is output to 52 and exposure is performed. At this time, the paper 52 is pulled out of the magazine 42, transported to the exposure point 41 by rollers 43 and the like, and exposed by the digital exposure means 51. Thereafter, normal photographic processing is performed to obtain a color print or the like. The operation of the entire photo processing apparatus 1 as described above is controlled by the operation unit 70.

A description of the processing device 61 and the color scanner device 62 will be omitted, and the image processing section 50 according to the present invention will be described below.

The image processing section 50 scans and reads the negative film F to obtain digital image data, image data and storage means 53, and performs an operation for correcting the amount of displacement as described later. This is constituted by arithmetic processing means 55 for performing the operation and digital exposure means 51 for scanning and outputting the corrected image data as exposure data to a paper 52 for writing. Hereinafter, each of these components of the image processing unit 50 will be described in more detail.

First, the reading means 54 scans and reads the entire predetermined scanning area S (FIG. 4) including the entire width of the negative film F by the color scanner 62 or the like, and obtains image data as digital data. Here, the "predetermined whole scanning area including the whole in the width direction" S is, as shown in FIG. 4, an image information ID area in which image information is recorded as a so-called image frame such as a negative film F, and a negative information area. A code area B (Ba and Bb) which is an edge of the film F, and both side areas C (Ca and Cb) set as "predetermined width portions" on both sides of the entire width direction of the negative film F. Means scanning and reading as image data. Note that the code area B is an area in which a part in which attribute data such as a type code relating to the negative film itself is recorded and a perforation are combined. The size of the “predetermined width portion” will be described later.

The storage means 53 stores image data read as digital data or corrected image data, and comprises a RAM, a ROM and the like.

The arithmetic processing means 55 is stored in the storage means 53 when the positional deviation of one edge in the width direction H perpendicular to the transport direction T of the negative film F is determined from the acquired image data. The data array of the scanning row in which the positional deviation has occurred among the image data obtained is subjected to arithmetic processing corresponding to the positional deviation as described later, and the image data corresponding to the positional deviation amount is corrected. Then, the corrected image data is sent to the digital exposure means 51 as exposure data. For this reason, the arithmetic processing means 55 is constituted by various well-known ordinary logic circuits and arithmetic circuits, registers, RAMs and the like.

The digital exposure means 51 exposes the corrected image data and writes it on the paper 52, and is constituted by the same digital exposure means as in the prior art. As described above, since the image processing unit 50 is configured by the ordinary calculation means and the like, the cost increase can be reduced and the photographic processing apparatus 1 can be configured.

Since the photographic processing apparatus is constructed as described above, it is not necessary to provide a film guide or apply a pressurization as in the prior art, so that the structure of the photographic processing apparatus can be simplified. Therefore, it is not necessary to adjust the dimensions of the film guide or replace the film guide, and the pressurizing mechanism can be dispensed with. Therefore, the cost can be reduced by eliminating these devices and parts and the work of adjusting them.

Next, the image processing unit 5 according to this embodiment
The basic concept of a method of correcting image data performed using 0 will be described. FIG. 3 conceptually shows image data of the meandering negative film 52b, and FIG. 4 shows a method of determining one edge or the like of the negative film F in order to correct the arrangement of the image data as shown in FIG. 5 is a partially enlarged view of FIG. 4, and FIG. 6 is a flowchart showing the correction method in the order of steps. In the drawing of the negative film F, perforations, type codes, and the like are omitted.

In the present embodiment, as shown in FIG. 3, the negative film F is displaced in the d and k rows of the scanning row, and thus the read image data is
Both ends of the negative film F and the image information ID are _denoted by a code _Fax.
And F _bx , the d column is in the x direction, F _ay and F _bx
As shown by, the k columns are shifted in the y direction.

Next, in FIGS. 4 and 5, the pixels schematically shown in FIG. 3 are indicated by dots in the same manner as the point P ₀ indicating the edge of the negative film F or the like. As shown in FIG. 4, “the entire scanning area” (Ia to Ia) including the entire width of the negative film F in the width direction.
The entire image is raster-scanned (for example, Sk, Sh) in the vertical direction H of the longitudinal direction T of the negative film F to scan and read the image data (step 92).

Therefore, the image data read by the reading means 53 is provided at both ends (Fa and Fb) of the negative film F.
Contains. At this time, as described above, the entire scanning area S is defined on both sides of the negative film F, including a “side area” C portion having a predetermined width such as a clearance ΔG defined by a conventional film guide. ing.

In FIGS. 3 and 4, for the sake of explanation, the meandering of the negative film F is schematically shown, so that only one scanning line is displaced by one pixel. However, in actuality, a larger number of rows may be continuously shifted in the longitudinal direction T of the negative film F, or a plurality of pixels may be shifted.

In the present embodiment, with one end (Fa or Fb) of the negative film F as a reference (origin), the arrangement of the image data of the scan line shifted in position is shifted by the position shift amount. In this manner, the data is corrected (shifted) to obtain exposure data. The calculation and identification of the distance between two points, etc., performed for such correction of the amount of displacement, are performed by counting the number of pixels existing between the two points.

First, of the image data of the entire scanning area S,
The distance Lc of the portion C (Ca or Cb) protruding from the negative film F, which is the both side regions described above, is obtained by calculation or setting. Then, from P ₀ (k, 0), the scanning row Sk
, A point on one edge of the negative film F (for example, P _i (k, i) shown) is detected from the pixel data obtained by the search, and the negative film is detected. By sequentially detecting these points on one edge of F and forming a point sequence, a boundary line (Fa or Fb) representing the boundary is determined to determine one edge of the negative film F (step 93).

As described above, the edge P of the entire scanning area S
_{Since 0} (k, 0) is set as the origin, one edge of the negative film F can be reliably grasped, and therefore, the positional deviation can be reliably corrected by the method described later.

At this time, the origin for determining the one edge of the negative film F is not limited to P ₀ (k, 0), but once the one edge of the negative film F is captured, it will be described later. As described above, the positional deviation of the one edge of the negative film F can be determined by “data disorder”, so that any line segment that can define a constant distance to the one edge of the negative film F may be used. Hereinafter, a method for determining one edge of the negative film F, that is, a boundary line will be described.

First, in discriminating the boundary line, the areas B and A in the negative film F indicate the distance representing each area,
The “predetermined distances” La and Lb are applied with P ₀ (k, 0) as the origin, and can be specified by the number of pixels from the origin. Then, of the image data on the scanning row Sk, the image data representing the entire negative film represents an area “Ba + A + Bb” from P _i (k, i) to P _f (k, f). Image data representing the information ID is P _m (k,
m) to P _n (k, n).
Here, the predetermined distance La or Lb can be set based on a nominal value or the like determined by the manufacturer of the negative film and the type of the product number.

Next, as shown in FIG. 5, the end edge of the negative film F (for example, P _i and Q _i) comprises, as a search range W of the band-like region along the conveying direction of the negative film F, the search Within the range W, pixel data for the width of this band is
Scan and search in the order of _{k + 1} , _{Sk + 2} , _{Sk + 3} ,..., and determine one edge of the negative film by a method of determining a boundary line from the image data on each scanning row. I do.

At this time, since the negative film itself is located on the boundary line, a change in reflected light or transmitted light related to the material of the negative film F can be observed, so that the boundary line can be determined. The size of the width of the search range W can be set based on the number of pixels necessary for determining such a boundary line. Therefore, the size of the width of the both-side region Ca can be appropriately set so as to include the search range W.

Then, while the search and determination are repeated within the search range W along the transport direction of the negative film F, if the corresponding one end edge does not exist due to the displacement, it cannot be determined (data (Step 9) (step 9)
3) In this case, the image data is searched for, for example, after returning to, for example, Q ₀ (h, 0), the distance Lc is searched again from Q ₀ (h, 0), and the negative film F is searched. Of the one edge Q _i-1 (h, i-1) of is determined.

In order to determine the boundary line, in addition to the above-described method, a conventionally known boundary line determination method (for example, a method using the connectivity of pixels having similar densities) is used. You can also.

As described above, the deviation amount is quantified and obtained.
The image data representing the entire negative film F is
In the whole film, Q_i-1(h, i-1) to Q_f-1(h, f
-1) in the area "Ba + A + Bb"
In the image data representing the ID, Q _m-1(h, m-1) to Q
_n-1It is in the area A up to (h, n-1).

Next, of the acquired image data, Sh
For example, since the image data of the columns are misaligned as shown in FIG. 3 (step 94), for example,
The correction is performed so that the arrangement of the image data is shifted by one pixel. In the case of a plurality of pixels, as described above, the shift amount is calculated from the number of pixels (step 95).

[0050] Then, the shifted sequence of image data by position shift amount (step _{96), Q i- 1 (h} , i-1) from the _{Q f-1 (h, f} -1) to the pixels up Related image data,
After the addresses from Q _i (h, i) to Q _f (h, f), which are regular addresses, are newly allocated and stored,
The image data can be updated by overwriting and updating the original image data for each address. According to this method, it is necessary to set a new address once, but the algorithm for correcting the arrangement of the image data is simple, the arrangement of the image data can be easily corrected, and a simple arithmetic processing unit is used. Can be corrected.

Alternatively, from Q _i-1 (h, i-1) to Q
_By replacing the image data relating to the pixels up to _f-1 (h, f-1) with the image data at the addresses Q _i (h, i) to Q _f (h, f), respectively. Can also be updated. According to this method, an additional address is not required, so that the storage capacity of the storage unit 53 is not reduced.

The positional deviation of the image data obtained as described above is corrected to obtain exposure data (step 97). The exposure data is digitally exposed on paper and the image data is written. The original image data of the negative film can be accurately formed at the appropriate position for the negative film with misalignment, so that regardless of the type of the negative film and the variation in width, it can be applied to any size negative film. In addition, any misalignment can be easily corrected for misalignment, and the paper 52
The negative film is not damaged by a film guide or the like.

Further, there is no need to position and attach or adjust the film guide or the like, and it is no longer necessary to adjust the pressurizing condition by providing a pressurizing mechanism for the negative film. Therefore, it is possible to simplify the structure of the photographic processing apparatus and reduce structural restrictions.

Embodiment 2 In this embodiment, in the image data after the displacement correction, the both side areas (areas Ca and Cb) and the code area (from one edge of the negative film to the edge of the image frame close thereto). Image data in the width direction areas up to, that is, the areas Ba and Bb) are skipped and rejected (ie, the image information I)
The configuration is such that the D area A) is used as exposure data, and the other configuration is the same as that of the first embodiment.

That is, when exposing the paper 52, the paper 5
If the positioning of No. 2 is performed separately and reliably, the writing position of the image data of the area A on the paper 52 can be adjusted to the predetermined position of the correctly positioned paper 52.

Therefore, since it is sufficient that the image data of the image information ID area A, which is photographic information, is used as the exposure data, the data of the respective areas B and C are rejected and the rest is stored in the storage means 53. Is used as exposure data. In this case, the size of the region B occupies nearly half of the width of the negative film F when the two regions (Ba and Bb) of B are combined, so that the size of the region B is smaller than that of the first embodiment. The capacity can be reduced by about half, the effect of saving the storage capacity is high, and the storage means 53 can be realized at low cost.

Embodiment 3 This embodiment is obtained by scanning the negative film F in the width direction H, and is the other end P _f ( k, f) or the other edge P _n (k, n) on the opposite side of the image frame is used for verifying the misalignment determination, and the other configurations are the same as those in the first embodiment.

That is, in the first embodiment, the “predetermined distance” can be applied to the area B (Ba, Bb) and the area A in the negative film F with the origin at P ₀ (k, 0). However, in the present embodiment, verification for such an application is performed. That is, the other end edge P
_f (k, f) or the other end edge P _n (k, n) according to the first embodiment.
Is determined in the same manner as in the above case, and a point separated by a “predetermined distance” from P ₀ (k, 0) is the other edge P _f (k, f) or the other edge P _n (k, k). Verify whether it matches n).

If they do not match, after taking measures such as issuing a warning, re-searching from P ₀ (k, 0) or revising the value of “predetermined distance” and the like, the image data array Is corrected. With the configuration according to the present embodiment, in addition to obtaining the same operation and effect as in the first embodiment, even if a malfunction related to the correction of the array of the image data has occurred, the malfunction can be detected. By determining the position shift of the negative film F, the original image data of the negative film can be accurately formed at an appropriate position.

In the first to third embodiments described above, the present invention is applied to the case of a negative film.
In addition, the present invention can be applied to a positive film.

The present invention further provides an image information ID area,
The distance to the image information ID area as in the case where image information is read as digital data from a hard copy original such as an image having a "blank area" with a certain width around the image information ID area, so-called "frame area". Is applicable when a line segment that can be defined as a constant is available. Also in this case, it is possible to scan and read the entire area including the line segment, correct the image data according to the gist of the present invention, and form a color print or a color copy.
The same operation and effect as those of the first to third embodiments are obtained.

[0062]

According to the image processing method of the present invention,
A predetermined entire scanning area including the entire width of the photographic film is scanned and read in the width direction to determine the positional deviation in the width direction, and the arrangement of the image data of the scanning line having the positional deviation is corrected. Any type (size) because it is exposure data
With respect to this paper, any positional deviation can be easily corrected, and the original image data can be written on the photosensitive material at an appropriate position. Therefore, the photographic film is not damaged. Further, since no mechanical correction means is required, the structure of the photographic processing apparatus can be simplified, and the cost of the apparatus and adjustment work can be reduced.

According to the image processing method of the present invention, a predetermined search range of one end of the entire scanning area along the transport direction of the photographic film is searched to determine one end of the photographic film, and Since the position shift can be determined,
The displacement can be reliably detected and the displacement can be corrected reliably.

According to the image processing method of the present invention, a correct address is set to each pixel of the image data of the scan row in which the position shift has occurred, and the position shift is performed by overwriting the acquired image data. Since the correction is performed, the algorithm for correcting the arrangement of the image data is simple, and the correction can be performed using simple arithmetic processing means.

According to the image processing method of the present invention, the address of each pixel of the image data of the scan row having the positional deviation is adjusted to the correct address, and the position of the image data is replaced by the acquired image data. Because you can correct the deviation,
Since there is no need to set a new address, the storage capacity of the storage means is not squeezed.

According to the image processing method of the present invention, of the image data, a code from one edge along the transport direction of the photographic film of the entire scanning area to an edge of an image frame close to the one edge. Since the image data in the area is skipped and the remaining data is used as the exposure data, it is not necessary to store the image data other than the image information portion, and the storage capacity of the storage means can be greatly reduced. Can be realized at cost.

According to the image processing method of the present invention, after determining the one edge of the photographic film, the other edge of the photographic film can be further determined to verify the correction for the positional deviation. In addition, it is possible to detect a malfunction in correcting the arrangement of the image data. Therefore, even when a malfunction or the like in correcting the arrangement of the image data occurs, the malfunction can be verified, and the misalignment can be determined more accurately.

In the photographic processing apparatus according to the present invention, when the positional deviation in the width direction of the image data is determined, the data array of the scanning row having the positional deviation of the image data stored in the storage means is arithmetically processed. With the configuration including the arithmetic processing means for correcting the displacement, there is no need to provide a film guide or apply a pressure to the photographic film. Further, it is possible to correct the arrangement of the image data with respect to the displacement of the photographic film in the width direction by using a simple arithmetic processing means and a storage means.

Therefore, it is possible to correct the arrangement of the image data for any kind of misalignment of any kind of photographic film and write the image data at an appropriate position on paper. Also, there are no structural restrictions such as providing a film guide, etc.
The cost of the photographic processing apparatus can be reduced by a structurally simple configuration.
