The driver 70 drives the film winding motor 74 and the lens driving motor 75. The driver 71 has a shutter drive motor 76
And a reflector driving motor 77 for moving a reflector of a strobe described later. driver
Numeral 72 drives the zoom drive motor 78 and the finder drive motor 79.

The photographing lens 10 is a zoom drive motor
A predetermined number of lenses are moved in the direction of the optical axis by a known cam mechanism receiving a rotational force of 78, and the focal length changes. In the finder optical system 30, the zoom lenses 36 and 37 are moved in the optical axis direction by a known cam mechanism that receives the rotational force of the finder drive motor 79, and the focal length changes. In FIG. 2, for the zoom lenses 36 and 37, the solid line indicates the WIDE end position, and the broken line indicates the TELE end position.

FIG. 9 shows the details of the strobe light emitting section 15 shown in FIG. The strobe light emitting unit 15 is provided with an optical panel (Fresnel plate) 40 fixed to the front of the camera body.
0, a reflector (reflecting plate) 402 disposed behind the optical panel 400, and a strobe light emitting tube 403 disposed inside the reflector 402. As shown in comparison with (A) and (B) in the same figure, the reflector 402 and the strobe light emitting tube 403 are driven by the above-described reflector drive motor 77 and integrally move in the front-rear direction of the camera.
The distance from the optical panel 400 can be changed.

FIG. 10 schematically shows changes in light distribution characteristics due to movement of the reflector 402 and the strobe light emitting tube 403. Reflector 402 and strobe light tube 4
If the distance between 03 and the optical panel 400 is relatively short, if the light distribution characteristic shown by the solid line in the figure is obtained, if this distance is changed long, the light distribution characteristic changes as shown by the broken line in the figure. . In other words, in the latter case, the peripheral light amount decreases more remarkably, and instead, the central light amount increases and the reach distance becomes longer.

The table memory 80 shown in FIG. 4 includes an optical panel of the reflector 402 and the strobe light emitting tube 403.
The appropriate movement amount from 400 is stored for each zoom position of the photographing lens 10.

Hereinafter, photographing will be described. In this camera, a photographing lens 10 having a zoom magnification of 3 is applied. Viewfinder optical system 30
Uses a zoom optical system with a zoom magnification of 6. That is, in this case, a finder optical system 30 having a zoom magnification higher than that of the photographic lens 10 is used as the finder optical system 30 that is not involved in the quality of the captured image.

In the range of the zoom magnifications 1 to 3 of the photographing lens 10, the angle of view of the viewfinder display image and the photographing angle of view are changed in conjunction with the zooming operation, similarly to a normal camera. When the zooming operation is further performed on the TELE side beyond this range, only the display image of the finder optical system 30 changes the angle of view while the shooting angle of view remains constant. In that case, the CPU 60 writes information H indicating the image range ratio between the display image of the finder optical system 30 and the photographed image into the storage element 54 (see FIG. 3) of the film cartridge 50.

Hereinafter, the zoom control processing performed by the CPU 60 in FIG. 4 and the processing for changing the light distribution characteristics of the strobe light emitting section 15 will be described with reference to FIGS.

FIG. 5 shows the flow of the overall control processing by the CPU 60. First, when the overall control process starts in Step P10, it is determined in Step P11 whether or not there is a change in the state of various switches of the camera. If there is no change in the switch, the internal clock is updated in step P13, and the process proceeds to step P11.
Return to

If it is determined in step P11 that a switch change has occurred, then in step P12, it is determined whether the switch is the main switch 64 (see FIG. 4). If so, then in step P14, the main switch change from OFF to O
It is determined whether the change is to N.

If it is determined that this is the case, then in step P15, an OPEN process for setting the zoom type photographing lens 10 to the standby state is performed, and then, in step P16, a process for setting the OPEN flag is performed. . On the other hand, in step P14, the change of the main switch is changed from ON to OFF.
If it is determined that the change to
After the CLOSE process for setting the zoom type photographing lens 10 to the retracted state is performed in step P18, in step P18, the OPE
Processing for resetting the N flag is performed.

After the OPEN flag is set or reset, or when it is determined in step P12 that the switch having changed is not the main switch 64,
The process shifts to Step P19. In this step P19, the OP
It is determined whether or not the EN flag is set, and if not, the process returns to Step P11. If the OPEN flag has been set, then in step P20, it is determined whether the correction mode switch 22 (see FIGS. 1 and 4) has been operated.

When the correction mode switch 22 is operated, the correction mode processing described later is performed, and when the correction mode switch 22 is not operated,
The process moves to Step P22.

In step P22, the zoom switch
It is determined whether or not 63 (see FIG. 4) is operated.
If the zoom switch 63 has not been operated, the process proceeds to Step P24 described later. On the other hand, if it is determined that the zoom switch 63 has been operated, a zoom process is performed in step P23. This zoom processing will also be described later in detail.

Next, in step P24, it is determined whether or not the release switch 62 (see FIG. 4) has been operated. If the release switch 62 has not been operated, the process returns to step P11. If the release switch 62 has been operated, the release process is performed in step P25, and the process returns to step P11.

Next, the correction mode processing performed in step P21 will be described with reference to FIG. When this subroutine process starts in step P70, then in step P71, the correction mode switch
It is determined whether or not the operation 22 is from OFF to ON.

Operation of the correction mode switch 22 is changed from OFF to ON.
If it has been operated to the side, it is determined in step P72 whether or not the correction flag has been set. If the correction flag has been set, the correction flag is reset in Step P73. If the correction flag has not been set, the correction flag is set in Step P74.

When the correction flag is set or reset, a process of updating the display of the LCD 66 (see FIG. 4) is then performed in step P75. This is a process of displaying or extinguishing the display indicating that the camera is in the correction mode. Next, in step P76, this subroutine processing ends, and the processing returns to the flow of FIG.

Next, the zoom processing performed in step P23 of FIG. 5 will be described with reference to FIG. When this subroutine process is started in step P30, it is next determined in step P31 whether or not the operation of the zoom switch 63 is for the TELE side.

If the zoom switch 63 has been operated to the TELE side, in step P32, the photographing lens 10 is
The side is zoomed by a predetermined amount. This zooming is performed by operating the zoom drive motor 78 by the driver 72. If it is determined that the operation of the zoom switch 63 is not to the TELE side, that is, if the zoom switch 63 is operated to the WIDE side, in step P33, the process of zooming the taking lens 10 to the WIDE side by a predetermined amount is performed. Is made.

When the zooming process to the TELE side or the WIDE side is performed as described above, next, in step P34, it is determined whether or not the zoom switch 63 is continuously operated. If the zoom switch 63 is continuously operated, in step P35, the photographing lens 10
It is determined whether the end position has been reached at the TELE end. If so, in step P37, the zoom drive motor 78
Is stopped.

If it is determined that the photographic lens 10 has not reached the TELE end position, it is determined in the next step P36 whether or not the photographic lens 10 has reached the WIDE end position. For example, in step P37, the operation of the zoom drive motor 78 is stopped.

If it is determined that the taking lens 10 has not reached the WIDE end position, the flow of the process returns to Step P34, and the same processing as described above is repeated therefrom. If it is determined in step P34 that the zoom switch 63 has not been operated, the operation of the zoom drive motor 78 is stopped in step P37.

It should be noted that the zoom drive motor
When 78 stops, the shooting lens 10 is
If the zoom ratio is within the range, the zoom position of the finder optical system 30 is also within the range of the zoom magnifications 1 to 3, as described above.
An image having the same angle of view as the viewfinder display image is taken. On the other hand, when the finder optical system 30 is in the range of zoom magnifications 3 to 6, the zoom position of the taking lens 10 is always at the TELE end position.

Next, at step P38, the photographing lens 10
Is detected. This detection is performed using, for example, the output of a linear encoder that detects the position of the zoom lens.

Next, in step P39, it is determined whether or not the camera is in the correction mode, that is, whether or not the aforementioned correction flag is set. If the correction flag is on, in step P40, the reflector 402 is referred to from the table memory 80 shown in FIG.
In addition, a process of obtaining the moving amount of the strobe light emitting tube 403 from the optical panel 400 is performed. If the correction flag is not set, in step P41, the reflector is referred to from the table memory 80 by referring to the "normal mode table".
Processing for obtaining the amount of movement of the 402 and the strobe light emitting tube 403 from the optical panel 400 is performed.

The above "normal mode table" and "correction mode table" are shown in Tables 1 and 2 below, respectively.
It is as shown in.

[0050]

[Table 1]

[0051]

[Table 2]

As can be seen by comparing Tables 1 and 2, when the zoom position of the taking lens 10 is common, the reflector 402
Also, the amount of movement of the strobe light emitting tube 403 from the optical panel 400 is greater in the one defined in the "correction mode table" than in the "normal mode table". In other words, when the "correction mode table" is referred to, the light distribution characteristics of the strobe have a more remarkable decrease in the peripheral light amount and a longer reach distance.

When the above-mentioned movement amount is obtained, the center light amount stored for each movement amount in the table,
The upper and lower light amounts and the left and right light amounts are stored in a memory (not shown) in association with the frame numbers.

The zoom position Z1 in Tables 1 and 2 is WI
The DE end position and the zoom position Z8 are TELE end positions, and the others are positions sequentially arranged between them.

Next, in step P42, the reflector is adjusted according to the movement amount obtained by referring to the table as described above.
Processing for moving the 402 and the strobe light emitting tube 403 is performed. This movement is performed by the reflector drive motor 77 shown in FIG. When this movement is completed, this subroutine processing ends in step P43, and the processing returns to the flow of FIG.

Next, the release process in step P25 shown in FIG. 5 will be described with reference to FIG. Step P
When the subroutine process starts at 50, a battery check is performed at step P51. In the next step P52, the quality of the result of the battery check is determined. If the battery does not satisfy the predetermined performance, the fact is displayed in, for example, a viewfinder in step P53, and the subroutine processing ends in step P62.

If it is determined in step P52 that the result of the battery check is good, then in steps P54, 55,
At 56, lens driving processing for distance measurement, photometry, and focusing is sequentially performed.

Next, in step P57, it is determined whether or not the shutter button 20 (see FIG. 1) has reached the predetermined depressed position P1, and if not, the subroutine processing ends in step P62, and the processing proceeds to FIG. Return to the flow.

If the shutter button 20 has reached the pressed position P1, then in step P58, the shutter button 20 is pressed at a predetermined pressed position P2 deeper than the pressed position P1.
Is determined, and if not, the process returns to step P57. If the shutter button 20 has reached the pressed position P2, then a release is made in step P59, and the photographing is completed.

Next, in step P60, the information G indicating the center light quantity, the upper and lower light quantity, and the left and right light quantity obtained in step P40 or 41 in FIG. Element 54 (FIG. 3)
See) and written. The information H indicating the image range of the display image of the finder optical system 30 described above is also
At this time, the data is written to the storage element 54.

This information writing may be performed by a contact method via a contact point, or may be performed by a non-contact method.

Thereafter, in step P61, the film 51 is fed by one frame, and then in step P62, this subroutine processing ends, and the processing returns to the flow of FIG.

The photographed cartridge 53 is taken out of the camera body 1 and subjected to a developing process at a developing shop in a city, for example, and the photographic latent image recorded on the photographic film 51 is visualized. From the negative film thus formed, a photographic print is formed using predetermined recording paper. At this time, a process for compensating for the shortage of the strobe peripheral light quantity according to the information stored in the storage element 54 is performed. , And pseudo zoom processing. Hereinafter, these processes will be described in detail.

FIG. 11 shows an outline of a photographic print system according to an embodiment of the present invention. This system includes an image handling apparatus 101 and a photographic printer 102 connected thereto.

In the present embodiment, the image handling apparatus 101 is a general-purpose personal computer in which a dedicated program is incorporated, and stores, as peripheral devices, a film scanner for reading the developed photographic film 51A and the photographic film 51A. Element 54 of cartridge 53 (see FIG. 3)
And reading means 103 for reading information stored in the storage means. Further, the image handling apparatus 101 is provided with a CD-R, a Zi
A media drive such as p is built in or externally provided. Also, a communication facility (not shown) for exchanging image data with another computer via the network 104 is provided.

The photographic printer 102 is a known digital photographic printer, which receives image data and output instruction information (for example, the number of prints, size, etc.) from the image handling apparatus 101 and performs print output based on these. .

In the above system, the image handling device 10
1 is for performing predetermined image processing on an image signal (image data) captured from the developed photographic film 51A,
This is transferred to the photo printer 102 and the CD-R
And the like on the medium 106. Further, the information G and H stored in the storage element 54 read by the reading means 103 are input to the image handling apparatus 101 from the reading means 103.

Next, the configuration of this system will be described with reference to FIG.
This will be described in detail with reference to FIG. Note that, among the components shown in FIG. 12, the functions related to image processing may be realized as the functions of the image handling apparatus 101, or may be incorporated as the functions of the photographic printer 102 or the film scanner. Therefore, FIG. 12 will be described without associating with FIG. 11 in particular.

As shown in the figure, a photographic image captured by the scanner 110 is processed by various image processing means 111 to 116, and then output as a photographic print by the printer 102.

The setup gradation / color processing means 111 is a means for automatically determining whether the exposure is under or over, and correcting the exposure to an appropriate value. The enlargement / reduction unit 112 is a unit that converts the pixel density in order to adapt the size of the print image to the width of the recording material (for example, roll-shaped print paper), and for pseudo zoom processing. The density correction means 113 is a means for adjusting the density of the image carried by the image signal for each part of the image, and the graininess suppression type sharpness enhancement processing means 114 is as described in JP-A-9-22460. This is means for performing sharpness suppression processing of a granular suppression type.

Further, in addition to the above series of image processing, 3D conversion processing means for image data for print output
By 115 and 116, color conversion is performed according to the characteristics of the printer. The 3D conversion processing differs depending on whether the read film is a negative film or a reversal film.

Next, a description will be given of the pixel density conversion for the pseudo-zoom processing performed by the enlargement / reduction means 112. The storage information H for each photographed frame is input from the reading means 103 to the scaling means 112. This storage information H indicates the image range ratio between the viewfinder display image and the photographed image as described above. The enlargement / reduction unit 112 performs enlargement / reduction (pixel density conversion) based on the image range ratio so that a print image in the same range as the viewfinder display image is obtained.

At this time, since the image captured when the finder optical system 30 is set in the range of the zoom magnifications 1 to 3 has the same angle of view as the finder display image as described above, the film recorded image The relationship between the sizes of the print images is as shown in (1) and (2) of FIG. That is, in this case, the recorded image of the frame F with the developed photographic film 51A shown in FIG.
As shown in (1), print processing for reproducing the recording material 200 of a predetermined size as it is is performed.

On the other hand, for an image photographed when the finder optical system 30 is set in the range of the zoom magnification from 3 to 6, the relationship between the size of the film-recorded image and the size of the printed image is as shown in FIG. ) And (3), and the pseudo zoom process is performed as appropriate.

As described above, according to the camera and the photographic print system, a photographic print as if a photographic lens with a zoom magnification of 6 was used while using the photographic lens 10 with an actual zoom magnification of 3 Can be obtained.

Next, the density correction processing by the density correction means 113 will be described. When the reading means 103 reads the storage information G for each photographed frame from the storage element 54 of the film cartridge 50 and inputs it to the density correction means 113, the density correction means 113 responds to the image signal carrying the image of the frame. Then, if necessary, a process for partially lowering the print density is performed so as to compensate for the insufficient peripheral light amount. The necessity of this processing, the correction area and the correction amount are determined according to a predetermined program based on the above-mentioned central light amount, upper and lower light amounts, and left and right light amounts indicated by the stored information G.

By performing the above-described density correction processing, even if the photographing is performed with the light distribution characteristic in which the peripheral light amount is greatly reduced with priority given to the stroboscopic distance, the density is optimized over the entire area in the plane. You can get a print.

In the above-described embodiment, the print density is partially corrected so as to compensate for the insufficient peripheral light amount of the strobe light. Insufficient exposure may occur on the entire screen, and according to the present invention, such insufficient exposure can be corrected.
