Based on the signal from the data reading means, the printing magnification and print range are adjusted by the angle of view adjustment means, and the film is moved by the print position adjustment means to align the trimming center with the print center position to perform trimming printing.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 shows the configuration of a part of the viewfinder of the camera according to this embodiment. In the figure, the light that has passed through the objective lens 10 reaches the eyepiece lens 12 after passing through the half mirror I1, and the image of the subject is observed. On the other hand, the light transmitted through the lighting glass 13 passes through the liquid crystal panel l4, is reflected by the mirror l5, passes through the adjustment lens 16, and is then reflected by the back surface of the half mirror 11 to reach the eyepiece lens (2).

The night crystal spring slot 14 is used to display a trimming frame using the dry key 17, and can be used either in the horizontal position shown in Figure 3 (A) or in the vertical position shown in Figure 3 (B). Display. These 1-rimming frames are each divided into three stages, such as H, ~H, ,V, and ~V3, and the trimming range is specified by selecting one of these.

Further, in order to shift the trimming center from the center position of the finder, the trimming frame displayed within the liquid crystal panel 14 is moved in the X and Y directions within the finder by the drive unit 17.

cpuis controls the driver 17 based on signals from the keyboard 20. Also, by controlling the recording section 21 based on the selected 1. rimming condition, the first
As shown in the figure, a horizontal reference position mark 28a for specifying the trimming center position, a vertical reference position mark 28b for specifying the trimming center position, and a view angle mark 29 for specifying the view angle size are printed on the side of the negative film 30. Note that the horizontal reference position mark 28a and the vertical reference position mark 28b are recorded at the center of each side of the determined {-rimming frame 38, so that the 1-rimming center position can be easily detected.

The keyboard 20 has the orientation of the trimming frame (for horizontal position,
1. A key 24 for adjusting the size of the rimming frame, 1. A key 25 for moving the rimming frame vertically and horizontally, and 1. A record for recording the ring mark as described below. A button 22 is provided.

Note that the reference numeral 27 is a photographing lens placed in front of the negative film 30.

FIG. 4 shows the configuration of a photographic printing apparatus that prints a negative film 30 on which trimming conditions have been recorded as described above. First, the mechanical configuration of the photographic printing apparatus will be explained along the optical path.

The printing light emitted from the light source 40 is passed through the cyan filter 4
1a, magenta filter 4lb, yellow filter 41
After passing through c, it enters the expansion box 42. The amount of insertion of these color filters 41a to 41c into the optical path is adjusted by a filter adjustment section 43, thereby adjusting the ratio and intensity of the three colors of the printing light. Further, the diffusion box 42 is a rectangular cylinder whose inner surface is a mirror surface, with diffusion plates arranged on both end faces thereof, and sufficiently diffuses the color-corrected printing light.

The printing light passing through the diffusion box 42 illuminates the negative film 30 on the film carrier 44 placed at the printing position. The negative film 30 is a single long film, and as described above, trimming marks are formed at predetermined frames.

The negative film 30 is then transported in the direction of the arrow (rightward in the figure) by a pair of feed rollers 45 and 46 arranged at both ends of the film carrier 44.

The pair of feed rollers 45 and 46 are interlocked by a chain or the like, and are driven by a pulse motor 47.

Furthermore, a film mask 47 is arranged on the negative film 30 to maintain the flatness of the negative film 30.

The film carrier 44 is configured to be slidable in the X and Y directions by a pulse motor 48, and is moved during trimming printing to align the printing center position with the trimming center. Note that the pulse motor 48 is actually controlled by two motors, one for the X-axis direction and the other for the Y-axis direction.

A data reading device 5 is located on the left side of the film carrier 44.
8 is placed, and 1 from the print position of the negative film 30
Trimming mark 28a recorded on the frame in front of the frame,
28b and 29 are detected.

This data reading device 58, as shown in FIG. A third image sensor 58c detects the mark 29. Note that the data reading device 58 may be located on the film carrier 44. Furthermore, if the trimming conditions are recorded in a barcode, a barcode league is used as the data reading device.

Next, the printing light that has passed through the negative film 30 passes through a zoom lens 60 for printing and reaches a color barber 64 whose exposure range is regulated by a paper mask 62, and transfers the image on the negative film 30 onto a color paper 64. exposed to light.

The zoom lens 60 is driven by a motor 66, and the printing magnification can be adjusted.

The paper mask 62 is driven in the longitudinal direction of the color paper 64 by a motor 68, and the exposure range is adjusted according to the trimming range. Also, Color Heper 6 4
One frame is pulled out from the paper roll 70, passes through a guide roller 72, and reaches a pair of pull-out rollers 76 driven by a pulse motor 74. Then, the exposed portion is cut by a cutter 78 placed next to the paper mask 62 and sent to a photo-developing device (not shown).

A shutter 82 whose opening and closing are controlled by a shank drive section 80 is arranged between the zoom lens 60 and the color barber 64, and exposure is performed by opening the shutter 82 for a certain period of time.

Further, a scanner 84 consisting of an image sensor and a lens is arranged diagonally above the print position, and measures the transmitted light at each point of the frame set at the print position. The output signal of this scanner 84 is supplied to a characteristic value extraction section 85, which will be described later.

Next, the structure of the control department of the photo printing apparatus according to this embodiment will be explained.

The characteristic value extraction section 85 extracts characteristic values such as average transmission density, maximum density, and minimum density for each color based on the output signal of the scanner 84 for each frame. The exposure calculation unit 86 calculates the exposure using these characteristic values and sends it to a controller 87, which will be described later.

The memory 87a stores each of the trimming frames H, to H. ，
Driver 90 (zoom lens, (60
), driver 91 (paper mask 6?). The control amount of each device of the driver 89 (color paper 64) is stored in advance, and is read out by the controller 87 at the time of trimming printing.

The controller 87 controls the printing apparatus in general, and controls the filter adjustment section 43 based on the signal from the exposure calculation section 86, and also controls the shank drive section 8.
0 drive control is performed. In addition, drivers 88, 89, 90
, 91.92 via pulse motor 54■ 74, 66
．． 68 and 48 respectively.

More specifically, when performing standard printing, the pulse motors 66, 68, and 47 are each fixed at predetermined reference positions, and the pulse motor 4774 is driven at a constant speed to perform printing. On the other hand, when performing trimming printing, the pulse motor 48 is driven based on the reference position information of the first image sensor 58a and the second image sensor 58b of the data reading device 58.
4 to align the trigon center with the print center position. Also, the viewing angle information of the third image sensor 58c (selected trimming frame H1~}{,,V,~
■ Read the data corresponding to 3) from the memory 87a,
Based on this data, the pulse motors 66 and 68 are controlled to adjust the printing rate, and the pulse motor 74 is also controlled to adjust the transport of the color paper 64.

Next, the operation and effects of the embodiment configured as described above will be explained.

To perform trimming, look through the finder of the camera during photographing, and first operate the keys 23 on the keyboard 20 to select whether the orientation of the trimming frame is horizontal (H) or vertical (V). As a result, the liquid crystal panel 14 is driven, and the largest trimming frame (}l or V) in the selected direction is displayed on the finder.

Next, operate the key 24 to select 1-rimming frame size. That is, enlargement and reduction operations are performed so that the trimming frame corresponds to the desired trimming range. Next, the trimming frame is set at a desired position by operating the key 25 to move the trimming frame vertically and horizontally.

Then, when all the trimming conditions as described above have been specified, the record button 22 is operated to record the reference position marks 28a, 28b and the angle of view mark 29 on the side of the negative film 30.

Next, after developing the negative film 30 on which the trimming information has been recorded as described above, it is loaded into a printer.
When a print start button (not shown) is operated, the first frame of the negative film 30 is set at the print position. At this time, if the frame set at the print position is a frame for standard printing, the focal length of the zoom lens 60 and the position of the Baber mask 62 are each fixed at the standard position.

Next, the printing light emitted from the light source 40 illuminates the negative film 30 after passing through the color filters 41a to 41c and the diffusion box 42. Then, the scanner 84 detects the light that has passed through the frames of the negative film 30,
The exposure calculation unit 86 calculates the exposure value, and based on this, the amount of insertion of the color filters 41a to 4lc into the optical path is adjusted.

After this adjustment, the shutter 82 is opened for a certain period of time and the first frame on the negative film 30 is printed in full size on the color paper 64.

After that, if only standard size pudding [・] follows,
The negative film 30 and the color barber 64 are transported at a constant speed and printed sequentially.

On the other hand, while the negative film 30 is being transferred, the data reading device 58 marks 1.
If a frame is detected, set the frame in the normal print position and print it on the scanner 8 in the same way as when printing on a four-way mark
4, the reference position marks 28a, 28b
The film carrier 44 is driven based on the detection result to align the trimming center with the print center position. Also, based on the data in the memory 87a, the zoom lens 60 is driven to adjust the focal length, and the paper mask 60 is adjusted.
2 to adjust the printing range and adjust the transfer of the color paper 64 accordingly.

Then, as in the case of standard printing, use the color filter 4.
Trimming printing is performed after color light adjustment is performed by driving 1a to 41c. Note that when the frame at the print position is to be subjected to both standard printing and trimming printing, standard printing is performed first, and then trimming printing is performed by adjusting the trimming reference position and printing magnification.

In this case, since the color filters 41a to 41c are maintained in the standard print state, color variations do not occur between the standard print and the trimmed print.

In the above embodiment, the marks indicating the trimming range and the trimming center are shown as dots, but the fifth
Bars 93a and 93b indicating the lengths of both vertical and horizontal sides as shown in the figure.
The trimming range and trimming center may be specified by using

Further, in the above embodiment, the trimming frame is divided into three stages, but the size of the frame may be changed continuously without any stage. If you take precautions in this way, you will have even more freedom in trimming.

Furthermore, as the display means for the trimming frame, two movable frame plates may be used in place of the liquid crystal panel, and the trimming range may be displayed by mechanically driving these frame plates mutually.

Furthermore, when the vertical trimming frame in the embodiment is used, instead of printing as is, it may be converted horizontally by 90 degrees using a prism or the like. In this way, it is possible to print at a large magnification as in the case of the horizontal direction.

[Effects of the Invention] As explained above, in the present invention, not only the angle of view but also the center position of the main subject is variable, so the effect is that cropping with a high degree of freedom can meet a wide range of demands from users. There is.
