In step S14, the print size is set by operating the read magnetic information or the size selection switch 271. Hereinafter, details of step S14 will be described.

FIG. 6 is a flow chart showing in detail the procedure for setting the display size in step S14 described above.
In step S14-1, the information in the memory 28 is read, and it is determined whether or not the print size is magnetically recorded on the film F. If it is determined that the print size is recorded on the film F, step S14-2 is performed. If it is determined that the print size is not recorded, the process proceeds to step S14-3. In step S14-2, the print size magnetically recorded on the film F is written in the memory 28, and the process proceeds to step S14A.

As described above, when it is determined in step S14-1 that the print size is not magnetically recorded on the film F, the process proceeds to step S14-3. In step S14-3, it is determined whether or not the size setting switch 271 has changed from off to on. If it is determined that the size has changed from off to on, the process proceeds to step S14-4, and it has not changed from off to on. If determined, step S
Proceed to 14-7. In step S14-4, the value of the set value A is increased by "1".

In step S14-5, the set value A = 4
If it is determined that the setting value A = 4, the process proceeds to step S14-6. In step S14-7, if the set value A = 0, the process proceeds to step S14-8, if the set value A = 1, the process proceeds to step S14-9, and if the set value A = 2, the step S1.
To 4-10, if the set value A = 3, step S14-1
Go to 1 respectively. When the set value A = 0,
This indicates that the size setting switch 271 is not operated after the value of the setting value A is reset to "0" in step S60.

When the set value A = 0, step S14-7
From step S14-8, the print size is set to the maximum in step S14-8. FIG. 7 (a)
Is the film F when the print size is set to the maximum
7B shows the image on the television screen in this case. As shown in FIG.
Since the screen frame of the television is vertically longer than the image frame of the film F, the upper and lower parts outside the film image are displayed in the television image. Therefore, the operator can directly confirm the print size display 30 optically projected at the bottom of the film image, and the size setting switch 27 can be seen while looking at this display 30.
1 can be operated to set the print size.

When the set value A = 1, step S14-7
From step S14-9, the print size is set to normal in step S14-9,
Proceed to 14A. When the set value A = 2, step S14-
7 to step S14-10, and step S14-
In step 10, the print size is set wide, and the process proceeds to step S14A. When the set value A = 3, step S1
It progresses from 4-7 to step S14-11, and step S1.
Set the print size to panorama in 4-11,
It proceeds to step S14A.

As described above, in step S14, when the print size information at the time of printing is magnetically written on the film F, the print information is printed on the film F by the magnetic information read in step S8. If is not written, the operator sets the print size by operating the size setting switch 271.

Next, in step S14A of FIG.
If it is determined that the print size determined in the procedure of step S14 is “normal size”, step S14
Proceed to 15. In step S15, if the TV type switch of the information input device 27 is set to "wide TV", the process proceeds to step S18, and if it is set to "normal TV", the process proceeds to step S19.

In step S14A, step S1
If it is determined that the print size determined by the procedure of 4 is the "wide size", the process proceeds to step S16. In step S16, if the TV type switch of the information input device 27 is set to "wide TV", step S2
Go to 0, and if "normal TV" is set, step S
Proceed to 21.

In step S14A, step S1
If it is determined that the print size determined by the procedure of 4 is the "panorama size", the process proceeds to step S17. In step S17, if the TV type switch of the information input device 27 is set to "wide TV", step S2
Go to 2 and step S if "normal TV" is set
Proceed to 23.

As described above, the print size is "normal size" and the TV type is "wide TV".
When it is, it progresses to step S18. Aspect ratio of normal size of print, aspect ratio of wide TV and CCD
The aspect ratios of 14 are 2: 3, 9:16 and 3: 4, respectively.
Therefore, in step S18, the upper and lower sides of the image of the CCD 14 are first masked to have an aspect ratio of 9:16, and an aspect ratio of 9:16.
The resulting image is further masked in the left-right direction and the aspect ratio is 2:
3 is assumed. FIG. 8A shows the image thus obtained. Wide TV cuts the top and bottom of a TV image with an aspect ratio of 3: 4, and the projected image is shown in FIG.
As shown in (d), the image is masked on the left and right.

As described above, when the print size is "normal size" and the TV type is "normal TV", the process proceeds to step S19. Normal size aspect ratio of print, aspect ratio of normal TV and CCD14
Have aspect ratios of 2: 3, 3: 4, and 3: 4, respectively. Therefore, in step S19, the upper and lower sides are masked to have an aspect ratio of 3 :.
4 is assumed. As a result, an image in which the top and bottom are masked as shown in FIG.

As described above, when the print size is "wide size" and the TV type is "wide TV", the process proceeds to step S20. Wide size aspect ratio of print, aspect ratio of wide TV and CCD 14
Since the aspect ratios of 9 and 16 are 9:16, 9:16, and 3: 4, respectively, the upper and lower sides of the image of the CCD 14 are masked to have an aspect ratio of 9:16 in step S20. FIG. 8B shows the image thus obtained. Wide TV cuts the top and bottom of the TV image with the aspect ratio of 3: 4 to display it.
The image displayed is an image as shown in FIG.

As described above, when the print size is "wide size" and the TV type is "normal TV", the process proceeds to step S21. The wide size aspect ratio of the print, the aspect ratio of the normal TV and the aspect ratio of the CCD 14 are 9:16, 3: 4 and 3: 4, respectively,
In step S21, the top and bottom are masked and the aspect ratio is 9:16.
And As a result, an image in which the upper and lower sides are masked as shown in FIG. 9B is obtained.

As described above, the print size is "panoramic size" and the TV type is "wide TV".
When it is, it progresses to step S22. Aspect ratio of print panorama size, aspect ratio of wide TV and CCD
The aspect ratios of 14 are 1: 2, 9:16 and 3: 4, respectively.
Therefore, in step S22, the top and bottom are masked so that the aspect ratio is 1: 2. FIG. 8C shows the image thus obtained. Since a wide television cuts and displays a TV image with an aspect ratio of 3: 4 by cutting the upper and lower parts, the displayed image is as shown in FIG. 8 (f).

As described above, when the print size is "panorama size" and the TV type is "normal TV", the process proceeds to step S23. Aspect ratio of print panorama size, aspect ratio of normal TV and CCD14
Have aspect ratios of 1: 2, 3: 4, and 3: 4, respectively. Therefore, in step S23, the upper and lower sides are masked and the aspect ratio is 1 :.
Let it be 2. As a result, an image in which the upper and lower sides are masked as shown in FIG. 9C is obtained.

On the other hand, if it is determined in step S14A that the print size is set to the maximum value, the process proceeds to step S24. In step S24, the captured image is displayed without a mask. As shown in FIG. 7C, since the image area 12 is set larger than the image of the frame of the film F, the image as shown in FIG. 7D is displayed.

When the processes of steps S18 to S24 described above are completed, the process proceeds from step S25 to step S25 shown in FIG. In step S25, the memory 2
The magnetic data of the film F is read from 8. Step S
In step 26, predetermined information of the magnetic data read in step S25, for example, only the year, month, day, hour, minute, and second stored in the magnetic data is displayed as a television image. The display data is appropriately selected because displaying all of the magnetic data is complicated and confusing. For example, the print size set in step S14 may not be displayed.

In step S27, the image pickup circuit 15 is activated to start photographing the image in the image area 12 by the CCD 14. In step S28, the state of the additional instruction switch of the information input device 27 is determined, and if it is determined that the additional instruction switch has changed from OFF to ON, then step S29.
If it is determined that there is no change, the process proceeds to step S32. In step S29, it is determined whether or not an additional print instruction has already been given. If it is determined that the additional print instruction has already been given, the process proceeds to step S30, and if it is determined that no additional print instruction has been given, the process proceeds to step S31. In step S30, the additional instruction stored in the memory 28 is erased, and the fact that the data has been changed is recorded in the memory 28. In step S31, a reprint instruction is written in the memory 28 and
The fact that the data has been changed is recorded in the memory 28.

In step S32, the information in the memory 28 is read, and if it is determined that the additional print instruction is set, the process proceeds to step S33, and if it is determined that the additional print instruction is not set, the process proceeds to step S34. In step S33, an additional print instruction mark is superimposed on the television screen as shown in FIG. 10 (b), while in step S34, FIG.
The additional instruction mark is not displayed as shown in (a).

In step S35, if it is determined that the personal computer 30 is not connected to the personal computer interface 29, the process proceeds to step S47 (FIG. 5), and if it is determined that it is connected, the process proceeds to step S36. Step S
At 36, communication is performed with the personal computer 30 via the personal computer interface 29, and data for displaying characters (superimpose) on the television screen is received from the personal computer 30. In step S37, as a result of the communication in step S36, if it is determined that the received data is the same type of data as the already displayed data, the process proceeds to step S40, and if it is determined that the data is not the same type of data, step S3 is performed.
Proceed to 8.

In step S38, the information input device 27
If it is determined that the external display switch is turned on, the process proceeds to step S42, and if it is determined that the external display switch is turned off, the process proceeds to step S39. In step S39, it is determined from the communication result in step S36 whether there is data to be additionally displayed. If it is determined that there is data to be additionally displayed, the process proceeds to step S43, and it is determined that there is no data to be additionally displayed. If so, the process proceeds to step S45.

As described above, if it is determined in step S37 that the received data is of the same type as the already displayed data, the process proceeds to step S40, and in step S40, the data is read from the memory 28 in step S26. The character display data on the screen displayed according to the information is rewritten to the character display data according to the information from the personal computer 30. For example, when date data is sent from the personal computer 30 with the date displayed on the screen as shown in FIG. 11A, the data shown in FIG.
The new date data sent from the personal computer 30 is rewritten as shown in. Subsequently, in step S41, the data in the memory 28 is rewritten with the data sent from the personal computer 30. That is, for example, when the display shown in FIG. 11A is rewritten to the display shown in FIG.
The data in the memory 28 is rewritten as in the case of changing the display data. In addition, information indicating that the data has been changed is recorded in the memory 28.

As described above, if it is determined in step S38 that the external switch is on, the process proceeds to step S42. In step S42, the data received from the personal computer 30 is displayed at the character display position on the television screen. For example, the already displayed display of FIG. 11A is replaced with the display of FIG. 11C.

As described above, when it is determined in step S39 that there is additional data to be displayed, the process proceeds to step S43, and in step S43, the data received from the personal computer 30 is additionally set as the display data. In step S44, for example, the display position of the already displayed character is moved as shown in FIG. 11A, and as shown in FIG. 11D, the additional data received from the personal computer 30 in the space generated by the movement. Is displayed. In FIG. 11D, it is displayed that the personal computer 30 is “Busy”.

As described above, when it is determined in step S39 that there is no additional data to be displayed, the process proceeds to step S45, and in step S45, the display position is changed. Subsequently, in step S46, the display position is changed. For example, the character data (shooting date) displayed as shown in FIG. 11A is moved to the upper left and replaced with the display shown in FIG.

Next, in step S47 shown in FIG. 5, the state of the hoisting switch of the information input device 27 is judged, and if it is judged that the hoisting switch is on, the routine proceeds to step S57, where it is judged to be off. If so, the process proceeds to step S48. If it is determined in step S48 that the rewind switch of the information input device 27 is on, the process proceeds to step S49, and if it is determined that the rewind switch is off, the process returns to step S14. In step S49, the illumination control circuit 25 is instructed to turn off the illumination light source 11. Step S50
Then, the image pickup circuit 15 is turned off and the photographing of the image area 12 by the CCD 14 is completed. In step S51, the motor control circuit 22 is instructed to rotate the motor 4 in the rewinding direction to rewind the film F into the cartridge 1.

Next, in step S52, the memory 2
8 is read, and the frames facing the image area 12 are step S30, step S31, step S40.
Alternatively, it is determined whether or not the data has been rewritten in step S58 which will be described later. If it is determined that the data has been rewritten, the process proceeds to step S53, and if it is determined that the data has not been rewritten, step S54.
Proceed to.

In step S53, the data of the frame facing the image area 12 is rewritten. In step S54, after waiting for the rewinding of one frame, step S54 is performed.
Go to 55. In step S55, it is determined whether or not the rewinding is completed. If it is determined that the rewinding is completed, the process proceeds to step S56, and if it is determined that the rewinding is not completed, the process returns to step S52. When the rewinding of the film F is completed, all the film F is stored in the cartridge 1 and the rotation of the film encoder 6 is stopped. Therefore, in step S55, it is detected that the rotation of the film encoder 6 is stopped and the rewinding is performed. Judge as completed. Next, in step S56, the motor control circuit 22 is instructed to stop the rotation of the motor 4. In this way, in steps S52 to S55, the data is rewritten one by one with respect to the frames whose magnetic data has been changed.

As described above, if it is determined in step S47 that the winding switch is off, the process proceeds to step S57. In step S57, the memory 28
It is determined whether or not the value of the set value A stored in is 0, and if it is determined that the value of the set value A is 0, the process proceeds to step S59, and the value of the set value A is If it is determined that it is not "0", the process proceeds to step S58. In step S58, the print size is written in the memory 28 according to the setting value A stored in the memory 28. Next, step S5
At 9, it is determined whether or not the frame displayed on the television screen is the final frame. If it is determined that the frame is the final frame, the process proceeds to step S49 described above. If it is determined that the frame is not the final frame, the process proceeds to step S60. In step S60, the set value A
Is reset to "0" and the process returns to step S6.

As described above, in the first embodiment, it is judged whether or not the print size of each frame is recorded as the magnetic data of the film F (step S14-).
1) If it is recorded, it is displayed on the screen with an aspect ratio according to the print size of the magnetic data (steps S15 to S24). When the print size is not recorded as the magnetic data, the print size of each frame is selected by the operator's operation (steps S14-3 to S14-11), and the aspect corresponding to the selected print size is selected. The ratio is displayed on the screen (steps S15 to S24), and the selected print size is magnetically recorded on the film F (step S53).

In the first embodiment, even if the magnetic data of the film F does not have information for specifying the print size, an arbitrary aspect ratio can be set by the size setting switch 271 and the image of each frame can be viewed. it can. Therefore, even when a frame on which magnetic information regarding the print size is not recorded is displayed on the screen, or even when a film on which magnetic information regarding the print size is not recorded is used, the image of the film is displayed on the screen according to the desired aspect ratio. be able to. In addition, since the print size information optically recorded on the film can be confirmed by displaying the entire image area on the screen (step S14-8), the screen can be displayed without confusion even if there is no print size magnetic data. You can set the above aspect ratio.

In the first embodiment, when the set value A is "0", that is, when the print size is not set, the entire image area is displayed on the TV screen (step S14-8), instead of displaying the entire image area, the print size may be temporarily set to a wide size and displayed in the wide size so that the operator can select the optimum print size. Further, the operator may be allowed to select with a switch whether to display the entire image area or display a wide size image.

In the first embodiment, a part of the screen is masked according to the magnetic data of the film F or the aspect ratio determined by the operation of the size setting switch 271. However, instead of masking the screen, each screen is masked. A boundary line or the like indicating a print frame corresponding to the print size of the frame may be displayed.

As shown in FIG. 13, the process waits for the cartridge 1 to be loaded in step S101, and then proceeds to step S102. If it is determined in step S102 that the detection switch 2 is on, the process proceeds to step S103, and if it is determined that the detection switch 2 is off, the process returns to step S101. In step S103, the motor control circuit 22 is instructed to rotate the motor 4 in the direction in which the film F is extruded, and the thrust of the film F is started. In step S4, it is determined from the rotation amount of the film encoder 6 that rotates with the thrust operation of the film F whether or not the film F has reached the spool. If it is determined that the film F has reached the spool, the process proceeds to step S105, and if not, If determined, the process returns to step S104.

In step S107, it is determined whether or not the interrupter 8A detects the perforation of the film F. If it is determined that the perforation is detected, the process proceeds to step S8, and if it is determined that the perforation is not detected, step S107 is repeated. When the interrupter 8A faces the perforation, the image pickup area of the film F does not yet face the image area 12, and the image pickup area of the film F becomes the image area 1 after the interrupter 8A detects the perforation.
Appears in 2.

In step S108, the magnetic reading circuit 17 is instructed to start reading, and the magnetic head 7 reads the magnetic data of the image pickup area facing the image area 12. The read data is output to the CPU 21, and this data is written in the memory 28. In step S109, the interrupter 8B causes the film F

When the illumination light source 11 is turned on, the film F is illuminated from the back side via the diffusion plate 10. In step S112, the initial value of the focal length of the taking lens 13 is calculated, and the process proceeds to step S113. In step S113, an instruction is issued to the AF / zoom control circuit 26 based on the calculation in step S112, and the taking lens 13 is zoomed to initialize the focal length.

In step S114, the print size is determined from the read magnetic information or the state of the size setting switch 272. The details of step S114 will be described below.

In step S114-2, the print size is set to the normal size, and the flow advances to step S114-5. In step S114-3, the print size is set to the wide size and the process proceeds to step S114-5. In step S114-4, the print size is set to the panoramic size, and the flow advances to step S114-5. Step S11
In 4-5, the print size set in steps S114-2 to 4 is recorded in the display size memory 40, and the process proceeds to step S114A.

On the other hand, if it is determined in step S114-1 that the size setting switch 272 is in the switching position of the contact A, the process proceeds to step S114-6 and step S1.
In 14-6, it is determined whether or not the print size is recorded as magnetic data of the film. If it is determined that the print size is recorded, the process proceeds to step S114-7. If it is determined that the print size is not recorded, the step S114-8 is performed. Go to.

In step S114-7, step S1
At 08, the print size of the magnetic data stored in the memory 28 is read from the memory 28, and the print size of the magnetic data is written in the memory 28.

In step S114-8, step S11
It is determined whether or not the print size is already set by the size setting switch 272 by determining the presence or absence of the data in the display size memory 40 recorded in 4-5. If it is determined in step S114-8 that the print size has been set by the size setting switch 272, that is, the print size has been written in the display size memory 40, step S114.
If it is determined that the print size has not been written, the process proceeds to step S114-10.

In step S114-9, step S14 is executed.
The size set in 1-5 is written in the display size memory 40. In step S114-10, the print size is set to the wide size. In step S114-11, the size (wide size) set in step S114-10 is written in the display size memory 40, and step S114

As described above, in step S114, if the print size is set by the size setting switch 272, the size setting switch 2 is set to the size.
When the print size is not set by 72, the print size is determined based on the magnetic information information of the film F.

Next, if it is determined in step S114A that the print size determined in the procedure of step S114 is "normal size", step S115.
Proceed to. In step S115, the TV in the operation switch
If the type switch is set to "wide TV", the process proceeds to step S118, and if it is set to "normal TV", the process proceeds to step S119.

In step S114A, step S
If it is determined that the print size determined by the procedure of 114 is the "wide size", the process proceeds to step S116. In step S116, if the TV type switch in the operation switch is set to "wide TV", the process proceeds to step S120, and if it is set to "normal TV", the process proceeds to step S121.

In step S114A, step S
If it is determined that the print size determined by the procedure of 114 is the “panorama size”, the process proceeds to step S117. In step S117, if the TV type switch in the operation switch is set to "wide TV", the process proceeds to step S122, and if it is set to "normal TV", the process proceeds to step S123.

As described above, the print size is "normal size" and the TV type is "wide TV".
When it is, it progresses to step S118. Normal size aspect ratio of print, aspect ratio of wide TV and CC
The aspect ratio of D14 is 2: 3, 9:16 and 3: 1, respectively.
Therefore, in step S118, the upper and lower sides of the image of the CCD 14 are first masked so that the aspect ratio is 9:16, and the aspect ratio is 9:16.
The image of 16 is further masked in the left-right direction to have an aspect ratio of 2: 3. FIG. 8A shows the image thus obtained. Since a wide television cuts and displays a TV image having an aspect ratio of 3: 4 by cutting the upper and lower parts, the displayed image is an image with left and right masked as shown in FIG. 8D.

As described above, when the print size is "normal size" and the TV type is "normal TV", the process proceeds to step S119. Normal size aspect ratio of print, aspect ratio of normal TV and CCD1

4 aspect ratios are 9:16, 9:16 and 3: 4, respectively.
Therefore, in step S120, the upper and lower sides of the image on the CCD 14 are masked so that the aspect ratio is 9:16. FIG. 8B shows the image thus obtained. Since a wide television cuts and displays a TV image with an aspect ratio of 3: 4 by cutting the upper and lower parts, the image displayed is as shown in FIG.

As described above, when the print size is "wide size" and the TV type is "normal TV", the process proceeds to step S121. The wide-width aspect ratio of the print, the aspect ratio of the normal TV, and the aspect ratio of the CCD 14 are 9:16, 3: 4, and 3: 4, respectively. Therefore, in step S121, the upper and lower sides are masked to have the aspect ratio of 9:16. As a result, an image in which the upper and lower sides are masked as shown in FIG. 9B is obtained.

As described above, the print size is "panoramic size" and the TV type is "wide TV".
When it is, it progresses to step S122. Aspect ratio of print panorama size, aspect ratio of wide TV and CC
The aspect ratio of D14 is 1: 2, 9:16 and 3: 1, respectively.
Therefore, in step S122, the upper and lower sides are masked to have an aspect ratio of 1: 2. FIG. 8C shows the image thus obtained. Since a wide television cuts and displays a TV image with an aspect ratio of 3: 4 by cutting the upper and lower parts, the displayed image is as shown in FIG. 8 (f).

As described above, when the print size is "panorama size" and the TV type is "normal TV", the process proceeds to step S123. Aspect ratio of print panorama size, normal TV aspect ratio and CCD1
Since the aspect ratios of 4 are 1: 2, 3: 4, and 3: 4, respectively, in step S123, the top and bottom are masked to have an aspect ratio of 1: 2. As a result, an image in which the upper and lower sides are masked as shown in FIG. 9C is obtained.

Go to step S125 shown in. In step S125, the magnetic data of the film F is read from the memory 28.
In step S126, predetermined information of the magnetic data read in step S125, for example, only the date of the shooting date, time, minute, and second stored as magnetic data is displayed as a television image. The display data is appropriately selected because displaying all of the magnetic data is complicated and confusing. For example, the print size set in step S114 may not be displayed.

In step S127, the image pickup circuit 15 is activated and the CCD 14 starts photographing the image in the image area 12. In step S128, the state of the additional print instruction switch of the information input device 27 is determined. If it is determined that the additional print instruction switch has changed from OFF to ON, the process proceeds to step S129, and if it is determined that it has not changed, step S129 is performed.

In step S132, the information in the memory 28 is read, and if it is determined that the additional print instruction is set, the process proceeds to step S133, and if it is determined that the additional print instruction is not set, the process proceeds to step S134. Step S1
In 33, as shown in FIG. 10 (b), the additional print instruction mark is imposed and displayed on the television screen, while step S134 is performed.
Then, the additional print instruction mark is not displayed as shown in FIG.

If it is determined in step S135 that the personal computer 30 is not connected to the personal computer interface 29, the process proceeds to step S147 (FIG. 15). If it is determined that the personal computer 30 is connected, the process proceeds to step S136. In step S136, the personal computer 30 communicates with the personal computer 30 through the personal computer interface 29, and the character display (superimpose) data is received from the personal computer 30 on the television screen. In Step S137, Step S1
As a result of the communication in 36, if it is determined that the received data is the same type of data as the already displayed data, the process proceeds to step S140, and if it is determined that the data is not the same type of data, the process proceeds to step S138. If it is determined in step S138 that the external display switch of the information input device 27 is on, the process proceeds to step S142, and if it is determined that the external display switch is off, the process proceeds to step S139. In step S139, the presence or absence of data to be additionally displayed is determined from the result of the communication in step S136,
If there is data to be additionally displayed, the process proceeds to step S143, and if there is no data to be additionally displayed, step S145.
Proceed to.

As described above, when it is determined that the data received in step S137 is the same type of data as the data already displayed, step S140.
In step S140, the character display data displayed on the screen according to the information read from the memory 28 in step S126 is replaced with the character display data according to the information from the personal computer 30. For example, FIG.
When date data is sent from the personal computer 30 with the date displayed on the screen as shown in 1 (a), the new data sent from the personal computer 30 as shown in FIG. 11 (b). It will be rewritten with the appropriate date data. Then step S14
In 1, the data in the memory 28 is rewritten with the data sent from the personal computer 30. That is, for example, FIG.
When the display shown in FIG. 10A is rewritten to the display shown in FIG. 10B, the data in the memory 28 is rewritten as in the case of changing the display data. Further, the information that the data has been changed is stored in the memory 28.

As described above, if it is determined in step S138 that the external switch is on, the process proceeds to step S142. In step S142, the data received from the personal computer 30 is displayed at the character display position on the television screen. For example, as shown in FIG.
The display of (a) is replaced with the display of FIG.

As described above, if it is determined in step S139 that there is additional data to be displayed, the process proceeds to step S143, and in step S143 the personal computer 30
The data received from is added to the display data. In step S144, for example, the display position of the already displayed character is moved as shown in FIG.
As shown in (d), the additional data received from the personal computer 30 is displayed in the space created by the movement. FIG.
In (d), it is displayed that the personal computer 30 is "Busy".

As described above, if it is determined in step S139 that there is no additional data to be displayed, the process proceeds to step S145, and in step S145, the display position is changed. Subsequently, in step S146, the display position is changed. For example, by moving the character data (shooting date) displayed as shown in FIG. 11A to the upper left,
Replace with the display shown in (e).

Next, in step S147 shown in FIG. 15, if it is determined that the winding switch of the information input device 27 is on, the process proceeds to step S158, and if it is determined to be off, the process proceeds to step S148. Step S1
In 48, if it is determined that the rewind switch of the information input device 27 is on, the process proceeds to step S150, and if it is determined that it is off, the process proceeds to step S149. In step S149, the display size memory is reset, and the process returns to step S114. In step S150, the illumination control circuit 25 is instructed to turn off the illumination light source 11. In step S151, the image pickup circuit 15 is turned off and the photographing of the image area 12 by the CCD 14 is completed. Step S
At 152, the motor control circuit 22 is instructed to output the motor 4
The film F in the cartridge 1 by rotating the film in the rewinding direction.
Rewind inside.

Next, in step S153, it is determined whether the information in the memory 28 is read and the frame facing the image area 12 has been rewritten in step S130, step S131, step S140 or step S159 described later. Judge whether
If it is determined that the rewriting has been performed, step S154
If it is determined that writing has not been performed, the process proceeds to step S155. In step S154, the data of the frame facing the image area 12 is rewritten. In step S155, the process waits until one frame is rewound, and the flow advances to step S156. In step S156, it is determined whether or not the rewinding is completed. If it is determined that the rewinding is completed, the process proceeds to step S157, and if it is determined that the rewinding is not completed, the process returns to step S153. When the rewinding of the film F is completed, all the film F is stored in the cartridge 1 and the rotation of the film encoder 6 is stopped. Therefore, in step S156, it is detected that the rotation of the film encoder 6 is stopped and the rewinding is performed. Judge as completed. Next, in step S157, the motor control circuit 22 is instructed to stop the rotation of the motor 4. In this way, in steps S52 to S55, the data is rewritten one by one with respect to the frames whose magnetic data has been changed.

As described above, when it is determined in step S147 that the winding switch is off, the process proceeds to step S158. In step S158, the print size is set in the display size memory 40,
If it is determined that the print size of the memory 28 and the print size of the display size memory 40 are different, it is determined that "the print size has been changed" and step S
Proceed to 159. The print size is not set in the display size memory 40, or the display size memory 40
If it is determined that the print size set in (1) is the same as the print size in the memory 28, it is determined that "the print size has not changed" and the process proceeds to step S160. In step S159, the print size recorded in the display size memory 40 is written in the memory 28, and the print size in the memory 28 is changed. Next, step S1
At 60, it is determined whether or not the frame displayed on the television is the final frame. If it is determined that the frame is the final frame, the process proceeds to step S150. If it is determined that the frame is not the final frame, the process returns to step S106.

As described above, in the second embodiment, when the print size is set by the size setting switch 272, the size setting switch 2 is set to the print size.
If the print size is not set by 72, the print size is determined based on the magnetic information of the film F. That is, in the second embodiment, the print size is set by giving priority to the operation of the operator, that is, the state of the size setting switch 272 (step S11).
