Note that, on the side opposite to the light source of the light control filter 3,
The setup filter 31 is disposed so as to advance and retreat with respect to the optical path of the original light L1.
Numeral 1 is not used at the time of reading an image, but is used at the time of starting the apparatus or the like, and is deviated from an optical path at the time of actual image reading.

Further, the photographic image processing apparatus 1 is provided with a film viewer 8 so that the image of the film set on the negative mask 6 is projected on the film viewer 8 so that the operator can view the image of the film. ing.

In the negative mask 6, the original light L 1 converted into parallel rays in the lens set 5 is guided by the negative mask 6 and passes through a negative or positive film located at the opening 61 of the negative mask 6. ing. Further, as shown in FIG. 2, for example, when a 135-type film having a width of 35 mm is used as the film, the size of the opening 61 of the negative mask 6 is set to 36 ± 0.3 mm in the lateral dimension a.
The area is set so that the vertical dimension b is 24 ± 0.3 mm.

The light transmitted through the film becomes image light L2 accompanied by an image formed on the film, and is introduced into image reading means 7 for reading the image of the image light L2. The image reading means 7 includes a line C for performing main scanning.
A CD image sensor 71 is used, and the line CCD image sensor 71 is housed in a housing 72. Inside the housing 72, a rotating mirror 73 for reflecting the image light L2 transmitted through the film and introducing the reflected image light L2 to the line CCD image sensor 71 is provided. The image light L2 transmitted through the film is reflected by the rotating mirror 73 and introduced into the line CCD image sensor 71 of the image reading means 7.

The rotating mirror 73 is adapted to rotate in the direction of arrow A about an axis extending in parallel with the line direction of the line CCD image sensor 71. The sub-scanning of the image light L2 is performed by rotating the mirror 73.

Accordingly, the original light L1 radiated from the light source unit 2 and converted into parallel rays by the lens set 5 passes through the film set in the opening 61 of the negative mask 6, and becomes image light L2. Are reflected by the rotating mirror 73 at predetermined angles and are sub-scanned while the image reading means 7

The main scanning is performed by the D image sensor 71, and the sub-scanning is performed by the rotation of the rotating mirror 73, so that the entire film surface appearing in the opening 61 of the negative mask 6 is read as an image.

Further, the photographic image processing apparatus 1 is provided with a controller 91 which is a control means 9 having substrates and the like for operating or controlling devices in the apparatus. The image light captured by the controller 71 is converted into a digital signal. As shown in FIG. 3, the digital signal is transmitted to the controller 91 and is input to the storage unit 92 of the controller 91.

Further, the read image input to the storage unit 92 is subjected to a resizing process in an image range setting unit 93 in the controller 91 so as to be within the range of the image to be printed on the photosensitive material.

In the resizing process, the size of the image read by the image reading unit 7 is smaller than that of the image read by the image reading unit 7. For example, the size of the image read by the image reading unit 7 is 36 ± 0.3 mm. Vertical dimension 24 ± 0.3m
m, the horizontal dimension is 35.5 based on the center of the image.
It is set so that the resizing process is performed on a rectangle so as to be ± 0.05 mm and a vertical dimension of 23.5 ± 0.05 mm.

Specifically, for example, when the size of an image read by the image reading means 7 is 3000 × 2000 pixels, a predetermined number of pixels around the image are deleted and the above-described size (horizontal size) is obtained. 35.5 ± 0.05mm, vertical dimension 2
(3.5 ± 0.05 mm).

Then, the resized image data is input to the storage unit 92 again and stored therein, and the stored image data is provided in the print processing apparatus 11 provided separately.
, A digital image of the film can be printed on the photosensitive material within the resized image range.

As described above, in the present embodiment, the image forming portion of the film is positioned at the opening 61 of the negative mask 6 through which the film is guided, and the image of the film is read by the image reading means 7. After the image read by the means 7 is stored in the storage unit 92 of the controller 91, the read image is stored in the image range setting unit 9 of the controller 91.
In step 3, the resizing process is performed on the range of the image to be printed on the photosensitive material, and the resized image data is stored again in the storage unit 92 of the controller 91.

The image data stored in the storage unit 92 of the controller 91 is transmitted to the print processing device 11.
In the line exposure section, an image of a predetermined size based on image data can be digitally printed on the photosensitive material in the line exposure section.

That is, in the present embodiment, the image of the film is read with a size equal to the area of the opening 61 of the negative mask 6, that is, the size of the image to be printed from the film onto the photosensitive material (image size). The read image is read by the image range setting unit 93 of the control means 9 so as to have an image size (image range) for printing on a photosensitive material. An image to be resized to be smaller than the size of the image and printed on a photosensitive material is set. Then, the resized image data is stored in the storage section 92 of the control means 9 so that an image of a predetermined size can be printed on a photosensitive material by digital printing based on the image data. .

Therefore, according to the present invention, the image to be printed on the photosensitive material is set by resizing the image read from the film, so that the image is printed on the photosensitive material through the opening of the negative mask, as in the prior art. It is not necessary to set the size of the image (the range of the image), and the range of the processing accuracy of the negative mask can be expanded more than before. As a result, the processing becomes easier and the processing time can be shortened. Therefore, production costs can be reduced.

Further, conventionally, the corner of the opening of the negative mask had to be machined so as to be a right angle. However, as in the present invention, the area of the opening is smaller than the opening of the negative mask. Since the image to be printed on the photosensitive material is set by resizing so that it becomes possible, it is possible to process the corners of the opening into a curved surface. Becomes easier.

Also, even with the same 135 type film,
Although two images may appear at the opening 61 of the negative mask 6 like a film taken by a half-size camera, conventionally, the size of the opening of the negative mask must be switched according to the image. did not become. However, according to the present invention, since the control unit 9 performs the resizing process and sets the burned image, the image range can be set by the resizing process without changing the size of the opening 61 of the negative mask 6. Accordingly, the range of mounting accuracy (positioning) when mounting the negative mask can be widened, and the structure of the negative mask can be a simple structure that does not require switching of the opening.

In the present embodiment, a film corresponding to a 135 type film having a width of 35 mm has been described.
The present invention can be applied to other films such as a 240 type film (APS) and a brownie film having a width of 61 mm.

Further, an image monitor is provided in the photographic image processing apparatus, an image read by the image reading means is displayed on the image monitor, and the read image is resized to an arbitrary shape on the monitor and the image data is processed. And the image data may be stored in the storage unit of the control unit. In this case, the image printing range and the character printing range can be freely set.

[0032]

According to the photographic image processing method and the photographic image processing apparatus of the present invention, an image on a film is read in a range larger than an image size (image range) for printing on a photosensitive material. The read image is processed by the image range setting unit of the control means so as to have an image size (image range) for printing on the photosensitive material, and the image is printed on the photosensitive material. Since an image is set and the image data in which the image range is set is stored in the storage unit of the control means, an image of a predetermined size can be printed on the photosensitive material based on the image data.

Therefore, by processing the image read from the film to the size of the image (image range) for printing on the photosensitive material, the range of the image printed on the photosensitive material is set. As described above, the range of the image to be printed on the photosensitive material does not have to be set by the opening of the negative mask, and the range of the processing accuracy of the negative mask can be expanded as compared with the conventional case. Thus, the processing time can be shortened, and the production cost can be reduced.
