The post-processing information input section 27 is used for the silver salt film 1.
After the end of photographing to 0, correction information such as exposure correction and color correction is input to the control circuit 30. In addition, the superimpose information output circuit 28 uses the subject image on the image monitor 21 to inform the user what information was input during post-processing for inputting correction information such as exposure correction and color correction. Superimpose information to be displayed on the monitor is outputted via the reproduction circuit 20.

When the mode in which the post-processing is not performed is set, the monitor time setting unit 29 determines how long the photographed subject image should be displayed after the photographing is finished, and inputs the signal to the control circuit 30, while When the mode for performing the post-processing is set, the signal is input to the control circuit 30 so that the photographed subject image is displayed until the post-processing is completed.

Further, the magnetic reading circuit 31 reads the information recorded on the magnetic recording layer of the silver salt film 10. In addition,
The control circuit 30 controls the operation of the entire camera system.

Next, the operation of the camera system of the present invention configured as above will be described. FIG. 2 is a flowchart showing the operation of the camera system when the post-processing is not performed in the first embodiment.

First, unlike a normal camera, the user confirms the subject image using the image monitor 21 instead of the optical viewfinder (step S1). The subject image on the image sensor 15 is photoelectrically converted and sent to the signal processing circuit 18.

Of the output signals from the signal processing circuit 18, the range-finding range selection circuit 22 detects only the signal within a predetermined range as an output difference from an adjacent pixel and becomes a contrast signal. The single focus lens 14 is driven through the lens controller 16.

Here, when the contrast becomes high, that is, when the subject image is in focus on the image pickup device 15, the single focus lens 14 stops. Although the convex lens 1 and the concave lens 2 which are photographing lenses are zoom lenses, the single focus lens 14 which is a lens for monitoring is a single focus lens. It is necessary to indicate the range captured by the convex lens 1 and the concave lens 2.

The angle of view of the monofocal lens 14 is set to be slightly wider than the angle of view of the convex lens 1 and the concave lens 2 at the wide angle. The signal processing circuit 18 outputs a signal corresponding to the angle of view of the convex lens 1 and the concave lens 2 as the photographing lens based on the outputs of the focal length detection units 6 of the convex lens 1 and the concave lens 2 as the photographing lens. Therefore, due to this signal, in the image monitor 21, the convex lens 1 and the concave lens 2 as photographing lenses are used.
A subject image corresponding to the angle of view of is displayed.

This display is performed by the processing flow of the signal processing circuit 18, the reproduction circuit 20, and the image monitor 21. Therefore, the movement of the subject can be monitored in real time on the image monitor 21, and even if the subject distance changes, the processing flow of the image sensor 15, the signal processing circuit 18, the distance measuring range selection circuit 22 and the lens control unit 16 can be performed. Since the single focus lens 14 is driven, the subject image is always in focus.

The user sets the focal lengths of the convex lens 1 and the concave lens 2 as the photographing lens to the focal length changing unit 5.
, The range of the object image signal output from the signal processing circuit 18 also changes, so that the single focus lens 14 as a monitor lens zooms. It is visible on the image monitor 21 (step S2).

Next, it is detected whether or not the second release (2nd release) button is pressed, and if the second release (2nd release) button is pressed, the next step S
Move to 4 and release if not pressed (2
The second release (2
The detection as to whether or not the (nd release) button has been pressed is repeated (step S3).

When the second release (2nd release) button is pressed, the photographing operation is started, and the position of the single focus lens 14 as the monitor lens is detected by the lens position detector 17.

Since the reciprocal of the object distance can be recognized from the output of the lens position detecting section 17 and the necessary extension amount of the convex lens 1 can be obtained from this and the output of the focal length detecting section 6, lens control The unit 7 extends the convex lens 1 to a predetermined position while watching the output of the lens position detection unit 8 (step S4).

Here, FIG. 3A is a diagram showing the relationship between the above-mentioned monofocal lens 14 and the position of the reciprocal of the object distance, and FIG. 3B is the reciprocal of the object distance and the need for the convex lens 1. It is a figure which shows the relationship with the delivery amount.

Next, the exposure calculation circuit 25 receives the film sensitivity information detected by the film information detection unit 24, and the exposure calculation circuit 25 outputs the brightness signal of each pixel by the output from the image pickup device 15. The photometric range selection circuit 23 outputs the average value from the luminance signal of the necessary area by the photometric range selection circuit 23.

From these, the exposure calculation circuit 25 calculates the shutter time and sends it to the shutter controller 4. Also,
When the control circuit 30 outputs an operation start signal to the shutter control section 4, the shutter 3 is opened for a predetermined time (step S5).

At the same time, the control circuit 30 also sends a signal to the memory 19 to integrate the subject image on the image pickup device 15 at the same timing as the exposure of the silver salt film 10 for the same time as the shutter time. , Are stored in the memory 19.

Further, the image monitor 21 has been monitoring the subject image in real time, that is, the moving image is displayed on the image monitor 21, but after the photographing, the subject image stored in the memory, that is, the still image is displayed. The image is displayed on the image monitor 21 for a predetermined time (step S6).

The predetermined time for displaying the still image on the image monitor 21 can be set to an arbitrary time by the monitor time setting means. However, if the next shooting is performed even within the set time, the above image monitor 2
The still image on 1 is switched to the moving image monitor by the shooting.

After photographing, the film feeding section 11 looks at the output of the film movement amount detecting section 12 and the silver salt film 1
Wind up 0 for one frame (step S7). While the film is being fed, the magnetic recording circuit 13 records a signal indicating no post-processing, a photographing date / time, a time and a signal regarding a photographing frame on the magnetic recording layer of the silver salt film 10 based on the output signal from the control circuit 30. (Step S8). Then, the process ends.

FIG. 4 is a diagram schematically showing the silver salt film 10 loaded in a cartridge. In FIG.
There is a silver salt film 10 loaded in the Patrone 50,
The magnetic recording layer 51 and the perforation 52 are provided on one side of the peripheral portion.

Next, a case where post-processing is performed on the spot after one frame is photographed will be described. FIG. 5 is a flowchart showing the operation of the camera system when post-processing is performed on the spot after one frame is photographed.

In this case, if the post-processing information input unit 27 is turned on before photographing, or is turned on during still image monitoring after photographing, post-processing becomes possible. Further, until the silver salt film 10 is exposed and the still image at that time is monitored on the image monitor 21, it is the same as the case without the above-mentioned post-processing.

First, unlike a normal camera, the user confirms the subject image using the image monitor 21 instead of the optical viewfinder (step S11). Here, the film winding is not performed when the post-processing mode is set before the shooting.

On the other hand, when the post-processing mode is set after photographing, one film of film has already been wound up, and in that case, one frame is rewound. In addition, the image sensor 15
The subject image above is photoelectrically converted and sent to the signal processing circuit 18.

Of the output signals from the signal processing circuit 18, the range-finding range selection circuit 22 detects a difference in output from an adjacent pixel as a signal within a predetermined range, and becomes a contrast signal. The single focus lens 14 is driven through the lens controller 16.

Here, when the contrast becomes high, that is, when the subject image is in focus on the image pickup device 15, the single focus lens 14 stops. Although the convex lens 1 and the concave lens 2 which are photographing lenses are zoom lenses, the single focus lens 14 which is a lens for monitoring is a single focus lens. It is necessary to indicate the range captured by the convex lens 1 and the concave lens 2.

The angle of view of the monofocal lens 14 is set to be slightly wider than the angle of view of the convex lens 1 and the concave lens 2 at the wide angle. The signal processing circuit 18 outputs a signal corresponding to the angle of view of the convex lens 1 and the concave lens 2 as the photographing lens based on the outputs of the focal length detection units 6 of the convex lens 1 and the concave lens 2 as the photographing lens. Therefore, due to this signal, in the image monitor 21, the convex lens 1 and the concave lens 2 as photographing lenses are used.
A subject image corresponding to the angle of view of is displayed.

This display is performed by the processing flow of the signal processing circuit 18, the reproduction circuit 20, and the image monitor 21. Therefore, the movement of the subject can be monitored in real time on the image monitor 21, and even if the subject distance changes, the processing flow of the image sensor 15, the signal processing circuit 18, the distance measuring range selection circuit 22 and the lens control unit 16 can be performed. Since the single focus lens 14 is driven, the subject image is always in focus.

The user sets the focal lengths of the convex lens 1 and the concave lens 2 as the photographing lens to the focal length changing unit 5.
, The range of the object image signal output from the signal processing circuit 18 also changes, so that the single focus lens 14 as a monitor lens zooms. It is visible on the image monitor 21 (step S12).

Next, it is detected whether or not the second release (2nd release) button has been pressed, and if the second release (2nd release) button has been pressed, the next step S
Move to 4 and release if not pressed (2
The second release (2
The detection as to whether or not the (nd release) button has been pressed is repeated (step S13).

When the second release (2nd release) button is pressed, the photographing operation is started, and the position of the monofocal lens 14 as the monitor lens is detected by the lens position detector 17.

Since the reciprocal of the object distance can be recognized from the output of the lens position detecting section 17, and the necessary extension amount of the convex lens 1 can be obtained from this and the output of the focal length detecting section 6, lens control The unit 7 extends the convex lens 1 to a predetermined position while watching the output of the lens position detection unit 8 (step S14).

Next, the exposure calculation circuit 25 receives the film sensitivity information detected by the film information detection section 24, and the exposure calculation circuit 25 outputs the brightness signal of each pixel as a signal processing circuit by the output from the image pickup device 15. The photometric range selection circuit 23 outputs the average value from the luminance signal of the necessary area by the photometric range selection circuit 23.

From these, the exposure calculation circuit 25 calculates the shutter time and sends it to the shutter controller 4. Also,
When the control circuit 30 outputs an operation start signal to the shutter control section 4, the shutter 3 is opened for a predetermined time (step S15).

At the same time, the control circuit 30 also sends a signal to the memory 19 to integrate the subject image on the image pickup device 15 at the same timing as the exposure of the silver salt film 10 for the same time as the shutter time. , Are stored in the memory 19.

Further, the image monitor 21 has been monitoring the subject image in real time, that is, the moving image is displayed on the image monitor 21, but after the photographing, the subject image stored in the memory, that is, the still image is displayed. The image is displayed on the image monitor 21 (step S16).

Next, the image monitor 2 shown in FIG.
While looking at 1, the post-processing information is input and determined (step S17). Then, when the input of the post-processing information is completed, the silver salt film 10 is wound up by one frame (step S18).

While the film is being fed, the magnetic recording circuit 13 records signals relating to the photographing date, time and photographing frame on the magnetic recording layer on the silver salt film 10 based on the output signal from the control circuit 30 (step S19). Further, the post-processing information is recorded on the magnetic recording layer on the silver salt film 10 (step S20). Then, the process ends.

FIG. 6 is a diagram showing post-processing information input from the post-processing information input unit 27, and FIG. 7 is an example of a state of a still image monitor when the post-processing information is input. Is.

Next, the post-processing information will be described. The exposure correction information is information that is input when it is desired to correct the overall brightness and darkness at the time of printing from the situation on the monitor. For example, + 1.0E when you want to make the whole a little brighter
Instruct V to bake.

Further, it is possible to consider an input method for correcting only a predetermined area, for example, only the face portion of a person who is backlit. Next, the color correction information is for instructing to emphasize a specific color when it is not reflected in the color tone that the user imagines.

The angle-of-view correction information is information for specifying only the angle of view when trimming processing is performed at the time of printing by using trimming information described later. For example, in the case where the image is taken in a wide angle, but it seems that it is better to take the image with a slightly longer focal length, the desired focal length is input, and the monitor of the actual focal length is displayed on the image monitor 21. The focal length input later is corrected and displayed.

The trimming information is such that, when a specific area on the monitor is designated, only the area portion is displayed on the entire image monitor 21 and only the above area is displayed on the entire print at the time of printing. Is.

When the aspect ratio information is input, for example, when it is desired to make a panorama after photographing, the print range is information indicated by a wavy line on the monitor as shown in FIG. 7 described later.

The number of prints is information for printing and delivering the designated number of prints. The date information is information indicating up to the date, time, and date when the image was captured when printing.

The photo CD creation information is information indicating whether or not to record the film on the photo CD when the photographed film is requested to the photo lab. After the above input, when it is input that the post-processing is finished, the film feeding is started, and the post-processing information is recorded on the magnetic recording layer in addition to the information when the post-processing is not performed.

Then, at the developing station, a print is created based on the post-processing information recorded on each frame of the film. The post-processing after the end of shooting has been described above. Next, the post-processing after the completion of rewinding is completed for one film even with the same post-processing.

FIG. 8 is a flow chart showing the post-processing after the filming of one film is completed and the rewinding is completed. In this case, the memory 19 is removable, and the film already taken and the memory 1 used at that time

The magnetic reading circuit 31 searches for a frame that matches the frame number of the monitor being reproduced on the image monitor 21 while searching the information of the magnetic recording layer, and stops the film feeding when the predetermined frame is found. (Step S34).

Then, the shooting date and time of the frame on the memory 19 and the shooting date and time of the magnetic recording layer on the silver salt film 10 are compared (step S35). If they do not match, the silver salt film 10 and the memory 19 match. Since there is not, a warning is issued (step S41). If they match, the search is OK, and the process proceeds to step S36.

Here, the post-processing information is input and determined while looking at the image monitor 21 shown in FIG. 7 (step S
36). Then, when the input of the post-processing information is completed, 1
While winding the frame film (step S37), the post-processing information is re-recorded on the magnetic recording layer on the silver salt film 10 (step S38).

The magnetic reading circuit 31 searches for a frame matching the frame number of the monitor being reproduced on the image monitor 21 while searching the information of the magnetic recording layer, and stops the film feeding when a predetermined frame is found. (Step S34).

Then, the shooting date and time of the frame on the memory 19 and the shooting date and time of the magnetic recording layer on the silver salt film 10 are compared (step S35). If they do not match, the silver salt film 10 and the memory 19 match. Since there is not, a warning is issued (step S41). If they match, the search is OK, and the process proceeds to step S36.
