Next, a CPU for controlling the camera 1 and related components will be described with reference to FIG. In addition,
FIG. 5 shows a photographing optical system, a finder optical system, and a liquid crystal display together with the control block of the camera 1.

The CPU 60 controls the camera 1 as a whole. The magnetic head control unit 61, the shutter control unit 62, and the film feeding control unit 63 are connected to the CPU 60. The magnetic head control unit 61 includes a CP
Under the instruction of U60, the magnetic head 80 writes or reads information such as the date, the number of prints, the title and the print size in the magnetic storage area 52 or 54 of the silver halide film 34. The shutter control unit 62 controls the opening and closing of the shutter 81 to expose the subject image formed by the photographing optical system 82 to the silver halide film 34. The film feed control section 63 feeds the silver halide film 34.

The CPU 60 is connected to an image pickup device readout circuit 64, a RAM 65, and a liquid crystal display control unit 66. By controlling the image pickup device readout circuit 64, the RAM 65, and the liquid crystal display control unit 66, a subject image is formed. The image is obtained and stored, and the image of the subject is displayed on the liquid crystal display unit 7a. That is, under an instruction from the CPU 60, the image sensor readout circuit 64 reads a subject image captured by the image sensor (for example, a CCD) 83 via the finder optical system 84, and transmits the subject image data to the CPU 60.
The CPU 60 stores the subject image data in the RAM 65. The liquid crystal display control unit 66 displays the subject image stored in the RAM 65 on the liquid crystal display unit 7a under the control of the CPU 60. Further, the CPU 60 instructs the liquid crystal display control unit 66 to read the handwritten information input to the liquid crystal display unit 7a by the pen 12, and receives the read handwritten information.

The ROM 67 stores a program for control processing by the CPU 60 and parameters used in the control processing in advance, and the timer 68 measures time under the control of the CPU 60. , Operation switch group 69 (including each switch on shutter button 8, zoom lever 10, and operation panel 9)
Is for accepting an operation by the photographer.

Next, the operation of the camera 1 will be described.
In the camera 1, when the normal mode is set by the mode selection switch 9e, when the shutter button 8 is pressed to expose the subject image to the silver halide film 34, the shooting information set and selected at that time and The development information is written in the magnetic storage area 52 or 54,
The silver halide film 34 is fed. On the other hand, when the handwriting mode is set, when the shutter button 8 is pressed to expose the subject image to the silver halide film 34, the image sensor 83
Liquid crystal display 7a on which a subject image picked up by the camera is displayed
Handwriting information can be input using the pen 12 on the screen, and the input handwriting information is written into the magnetic storage area 52 or 54 together with other photographing information and development information. Is fed. Hereinafter, an operation flow of the camera 1 at the time of silver halide film exposure will be described with reference to FIG.

FIG. 6 is a flowchart of a film exposure process in the camera 1. This is a process performed when the shutter button 8 is pressed. In this exposure process,
First, in step S1, the CPU 60 instructs the shutter control unit 62 to open the shutter 81 for a predetermined time, and exposes a subject image formed by the photographing optical system 82 to a photographing frame of the silver halide film 34.

Subsequently, in step S2, the CPU 60
Determines which of the handwriting mode and the normal mode is set by the mode selection switch 9e. If it is determined that the mode is set to the normal mode, the process proceeds to step S6, and if it is determined that the mode is set to the handwriting mode, the process proceeds to step S3. In step S3, the CPU 60 resets and starts the timer 68.

In step S4 following step S3, C
The PU 60 determines whether the write switch 9f has been pressed. If it is determined that the write switch 9f has been pressed, the process proceeds to step S7; otherwise, the process proceeds to step S5. In step S5, the CPU 60 receives time from the timer 68 (elapsed time from the start of the timer 68), and determines whether or not the time has exceeded a predetermined reference time (for example, 10 minutes). If it is determined that the reference time has been exceeded, step S
Go to step 6, otherwise return to step S4.

That is, the loop consisting of steps S4 and S5 is a process that is repeatedly performed as long as the write switch 9f is not pressed and the reference time is not exceeded. Then, if the time exceeds the reference time, the process exits the loop and proceeds to step S6. While this loop is being performed repeatedly, the subject image captured by the image sensor 83 and read by the image sensor read circuit 64 immediately before the shutter button 8 is pressed is read via the liquid crystal display controller 66 via the liquid crystal display unit 7a. And the photographer draws handwriting information on the liquid crystal display unit 7a using the pen 12. FIG. 2 shown above shows how handwriting information is input during the loop repetition period.

Step S6 is performed when it is determined in step S2 that the normal mode is set, or when it is determined in step S5 that the reference time has been exceeded. In this step S6, the CPU 60
It instructs the film feed control section 63 to feed the silver halide film 34 by one frame. At the time of this feeding, the CPU 60
Is the date set by the D switch 9a, the number of prints set by the PQ switch 9b, the ST switch 9
c and the print size selected by the CHP switch 9 d are transferred to the silver halide film 3 by the magnetic head 80 via the magnetic head control unit 61.
4 in the magnetic storage area 52 or 54. When the processing in step S6 ends, the film exposure processing ends.

Steps S7 and S8 correspond to step S4
Is performed when it is determined that the write switch 9f has been pressed. In step S7, the CPU 60 reads out, via the liquid crystal display control unit 66, the handwriting information drawn on the liquid crystal display unit 7a by the photographer or the like using the pen 12 during the repetition of the loop including steps S4 and S5. When reading out the handwritten information, it may be read out as image information or may be converted into character code information.

In the following step S8, the CPU 60 instructs the film feed control section 63 to change the silver halide film 34 by one.
Feed only the pieces. At the time of this feeding, the CPU 60 transmits not only the set / selected date, the number of prints, the title and the print size, but also the handwritten information read out in step S7 via the magnetic head control unit 61. The head 80 magnetically stores data in the magnetic storage area 52 or 54 of the silver halide film 34. When the processing in step S8 ends, the film exposure processing ends.

As described above, when the photographer sets the camera 1 to the handwriting mode by operating the mode setting switch 9e and then presses the shutter release button 8 to expose the subject image to the silver halide film 34, almost simultaneously with the exposure. Handwriting information can be input using the pen 12 on the screen of the liquid crystal display unit 7a on which the subject image captured by the imaging element 83 is displayed. Then, the photographer sets the writing switch 9 within the reference time.
By pressing f, the input handwritten information can be magnetically stored in the magnetic storage area 52 or 54 of the silver halide film 34 together with other photographing information and development information.
Therefore, the photographer can easily write an arbitrary message (handwritten information) for each photographed frame and store the message in the magnetic storage area 52 or 54 of the silver halide film 34.

At the time of printing, the message (handwritten information) magnetically stored in the magnetic storage area 52 or 54 of the silver halide film 34 includes, along with other photography information and development information, the subject exposed to the silver halide photosensitive layer of the photography frame. The image is drawn on the front or back of the printed photographic paper. The relative positional relationship between the subject image on the printed photographic paper and the handwritten information can be determined by the photographer using the pen 1 on the screen of the liquid crystal display unit 7a.
2 is preferably the same as the relative positional relationship between the subject image displayed on the screen and the handwritten information when the handwritten information is input using No. 2.

The handwritten information is stored in the magnetic storage areas 52 and 54.
Instead, the information may be stored in a magnetic storage area provided on the photographing frame 48.

[0034]

As described above in detail, according to the present invention, the subject image picked up by the image pickup device is displayed on the screen of the display means, and the handwritten information is displayed on the screen of the display means. Is entered. Then, the inputted handwritten information is magnetically stored in the magnetic storage area of the silver halide film by the magnetic storage means.

With such a configuration, the photographer can easily describe an arbitrary message (handwriting information) for each photographing frame and store the message in the magnetic storage area of the silver halide film. At the time of printing, a message (handwriting information) magnetically stored in the magnetic storage area of the silver halide film is drawn on the front or back surface of the photographic paper on which the subject image exposed on the silver halide photosensitive layer of the photographic frame is printed. Can be.
