FIG. 7 is a flow chart showing the operation of the CPU 30 during reproduction. Below, according to this flow, CP
The operation of U30 will be described. For example, if this flow starts in the state where the image (single-shot mode image) 3c on the developed film 3 is being reproduced (see FIG. 5), in step (hereinafter abbreviated as S) 101, the frame advance switch 36 is set. It is determined whether or not it has been operated. When the frame feed switch 36 is operated, the process proceeds from S101 to S102, the reproduction is stopped and the process proceeds to S103, where the feed motor drive circuit 32 drives the feed motor 15 to move the film 3 by one frame.

Further, at this time, the process proceeds to S104, the reading of magnetic recording by the magnetic head 13 is started, and S10
At 5, 106, the continuous shooting ID; C and the continuous shooting start ID; S recorded on the next frame 3d magnetic track 3m sliding on the magnetic head 13 are read. Here, continuous shooting ID; C = 1,
The continuous shooting ID; S = 1 is read.

Thereafter, the process proceeds to S107 to stop the magnetic recording reading, and then, in S108, the photo sensor 12 is read.
Determines whether or not a predetermined time has elapsed after the perforation 3a is detected, that is, whether or not one frame has been completed. If not completed, the film 3 is continuously fed, and if completed, In step S109, the feeding motor 15 is stopped to stop the feeding of the film 3. At this time, the next frame 3d is positioned at the image pickup position.

Next, in S110, the value of the continuous shooting ID "C" read in S105 is determined. Here, since C = 1, the process proceeds to S111, and the value of the continuous shooting ID "S" is determined. Since S = 1 here, the process proceeds to S112, and the value of the continuous shooting ID “C” recorded on the magnetic track 3l of the immediately preceding frame 3c is determined. Since C = 0 here, the process proceeds to S117. Note that the continuous shooting I of the immediately preceding frame 3c is performed.
D "C" is a value read in frame advance before the frame 3c is reproduced and recorded in a memory (not shown) in the CPU 30.

In S117, the image of the frame 3d projected on the CCD 11 is picked up, and the image signal is recorded in the memory 34 in S118. Then, the process returns to S103, and the feeding motor 15 is energized again to start frame feeding. To be done.

Then, in S104 to S107, the next frame 3

The continuous shooting ID "C" and continuous shooting ID "S" recorded on the magnetic track 3p of the next frame 3f are the same as those of the previous frame 3.
Since it is the same as that of the previous frame 3e, the image of the frame 3f is picked up through the same steps as in the case of the previous frame 3e (S117), the obtained image signal is recorded in the memory 34, and S10 is again recorded.
Return to 3 and start frame advance.

In S104 to S107, the continuous shooting ID; C = 1, continuous shooting start ID; S = 1 recorded on the magnetic track 3q of the next frame 3g is read, and when the frame 3g reaches the image pickup position (S108, In S109) and S110, the continuous shooting ID "C" recorded on the magnetic track 3q is determined. Here, since C = 1, the process proceeds to S111, and the continuous shooting ID "S" is determined. Since S = 1 here, S
In step 112, the continuous shooting ID "C" recorded on the magnetic track 3p of the previous frame 3f is determined. Here C = 1
Therefore, the process proceeds to S113.

The values of the continuous shooting ID "C" and the continuous shooting start ID "S" of the frame 3g are both "1" and the value of the continuous shooting ID "C" of the preceding frame 3f is "1". As a result, it can be determined that a series of continuous shooting scenes has ended up to the previous frame 3f and another continuous shooting scene has started from frame 3g. Therefore, the images of the frames 3d, 3e, 3f of the series of continuous shooting scenes recorded in the memory 34 in S113 are simultaneously displayed on the TV monitor 18 as shown in FIG. Although FIG. 1 shows a state in which 6 images are displayed simultaneously,
In this example, the three images are arranged so as to be most easily viewed and edited so as to be displayed on the screen.

After that, it is determined whether or not the frame advance switch 36 has been operated. When it is not operated, the reproduction and display of the continuously shot images are continued, and when it is operated, the process proceeds to S115 and is displayed on the TV monitor 18. The reproduction of the continuous shot image that has been performed is stopped, the recording in the memory 34 is cleared in S116, and then the process proceeds to S117 to capture the image of the frame 3g at the current capture position.

Subsequently, the image signal obtained in S117 is recorded in the memory 34 (S118), and the process returns to S103.
Start frame advance. The continuous shooting ID “C” and the continuous shooting ID “S” of the next frame 3h and the next frame 3i are both C =
Since 1 and S = 0, as in the case of the frames 3e and 3f, the image pickup (S117) and the recording of the image signal in the memory 34 (S118) are repeated, and then the process returns to S103 again and the frame is advanced. Do. At this point, the memory 34
In this case, a series of continuous shooting scene image signals of frames 3g, 3h, 3i is recorded.

In the next steps S104 to S107, the continuous shooting ID recorded on the magnetic track 3t of the next frame 3j; C = 0,
When the continuous shooting start ID; S = 0 is read and the next frame 3j reaches the imaging position (S108, S109), S110
The continuous shooting ID recorded on the magnetic track 3t
Determine "C". Since C = 0 here, S1
In step 19, the value of the continuous shooting ID "C" of the immediately preceding frame 3h is determined. Since C = 1 here, the process proceeds to S120.

Since the value of the continuous shooting ID "C" of the current frame 3j is "0" and the value of the continuous shooting ID "C" of the immediately preceding frame 3h is "1", It can be determined that the series of continuous shooting scenes has ended up to frame 3h. Therefore, in S120, the frames 3g, 3h, 3 recorded in the memory 34 are recorded.
Images of a series of continuous shooting scenes of i are simultaneously reproduced on the TV monitor 18. After that, when the frame advance switch 36 is operated (S121), the reproduction of the continuous shooting scene is stopped (S12).
2) The memory 34 is cleared (S123), and the image of the top 3j at the current image capturing position is captured (S124).
Normal playback of one frame is performed on the V monitor 18 (S10).
