[0008]
FIG. 2 shows the overall circuit configuration of the electronic still camera 10 of FIG. In FIG. 1, reference numeral 31 denotes an optical system, which includes a lens unit 12, a shutter 32, an image pickup device 33 such as a CCD (Charge Coupled Device), and the like, and focus, exposure, and the like are automatically adjusted by an autofocus mechanism and an EE mechanism. It has become. A shutter control circuit 34 controls the shutter 32 according to the operation of the release switch 13. The release switch 13 is connected to the shutter control circuit 34 via signal lines 36a and 36b. When a finger of the release switch 13 is touched (lightly pressed), a touch signal is transmitted via the signal line 36a to the shutter control circuit 34. When the release switch 13 is pressed, an ON signal is output to the shutter control circuit 34 via the signal line 36b. The shutter control circuit 34 enters a standby mode when a touch signal is sent from the release switch 13, determines focus and exposure by an auto focus and EE mechanism, and operates the shutter 32 at intervals of, for example, 1/60 second. .
[0009]
Then, with the operation of the shutter 32, a subject image is formed on the surface of the image pickup device 33 via the lens unit 12 and the shutter 32, and a signal from the image pickup device 33 to the subject image, that is, an image pickup signal is converted into a signal processing circuit 37. Sent to The image pickup device 33 is configured by, for example, arranging a large number of photoelectric conversion semiconductor cells, and the signal processing circuit 37 sequentially scans these cells to generate a video signal according to a general television signal, that is, a luminance signal Y. And color difference signals RY and BY. The image signal output from the signal processing circuit 37 is sent to the display control circuit 38 via the signal line a, sent to the modulation circuit 39 via the switch SW1, and A / D converted via the switch SW2. It is sent to the circuit 41. The switches SW1 and SW2 are on / off controlled by switch signals S1 and S2 from the control circuit 44. The A / D conversion circuit 41 converts the luminance signal Y and the color difference signals RY and BY sent from the signal processing circuit 37 into digital data, respectively, and outputs the digital data to the IC card 18. Image data sent from the A / D conversion circuit 41 is sequentially stored in the IC card 18 under the control of the memory control circuit 43. The memory control circuit 43 receives a control signal from the control circuit 44 and a shutter signal from the shutter control circuit 34. The memory control circuit 43 controls writing of image data to the IC card 18 when an ON signal of the release switch 13 is given from the shutter control circuit 34 in the photographing mode.
[0010]
On the other hand, the memory control circuit 43 reads an image stored in the IC card 18 in response to a control command from the control circuit 44 and inputs the read image to the D / A conversion circuit 45. The image read from the IC card 18 is converted into an analog signal by the D / A conversion circuit 45 and sent to the display control circuit 48 via the signal line b.
[0011]
The modulation circuit 39 modulates a signal supplied from the signal processing circuit 37 via the switch SW1 and outputs the signal to the recording circuit 46. The recording circuit 46 drives the recording head 47a based on the signal sent from the modulation circuit 39, and records image information on the magnetic sheet stored in the FD 17 so as to form an annular track.
[0012]
The image information recorded on the FD 17 is read by the reproducing head 47b (generally shared with the recording head 47a) in the reproducing mode, and sent to the demodulating circuit 52 via the reproducing circuit 51. The demodulation circuit 52 demodulates the reproduced signal, inputs the demodulated signal to the encoder 53, returns the original luminance signal Y and color difference signals RY, BY to the display control circuit 38. The display control circuit 88 selects three types of image signals input through the signal lines a, b, and c in accordance with an instruction from the control circuit 44, and outputs them to the finder 14 and the liquid crystal display panel 16 for display.

Thus, when taking a picture with the electronic still camera configured as described above, the photographing mode is designated by operating the key of the key input unit 15. When the captured image is to be stored in the IC card 18, a write mode for the IC card 18 is designated. The operation when the IC card write mode is designated will be described below. The control circuit 44 outputs a control signal to the memory control circuit 43 and turns off the switches SW1 and SW2 according to the mode designation such as the photographing mode and the IC card writing mode. Further, the control circuit 44 instructs the display control circuit 88 to select the signal line a and output it to the finder 14. In this state, when the photographer touches the release switch 13 with his finger lightly, a touch signal is sent to the shutter control circuit 34 via the signal line 36a. When a touch signal is sent, the shutter control circuit 34 enters a standby mode, determines focus and exposure by the auto-focus mechanism and the EE mechanism, and operates the shutter 32 every 1/60 second. As a result, a subject image is formed on the surface of the image sensor 33 via the lens unit 12 and the shutter 32, and a luminance signal Y and color difference signals RY and BY corresponding to the projected image are output from the image sensor 33, The signal is sent to the display control circuit 38 via the signal line a.

[0016]
When the shutter ON is given, the control circuit 44 turns on the switches SW1 and SW2 for a certain time, for example, 1/60 second. When the switches SW1 and SW2 are turned on, the output signal of the signal processing circuit 37 at the time when the release switch 13 is turned on, that is, the luminance signal Y and the color difference signals RY and BY are modulated by the modulation circuit 39 and the A / D. It is input to the conversion circuit 41. The modulation circuit 39 modulates the image signal sent from the signal processing circuit 37 and outputs the modulated image signal to the recording circuit 46. The recording circuit 46 drives the recording head 47a based on a signal from the modulation circuit 39, and records image information such that an annular track is formed on a magnetic sheet stored in the FD 17. On the other hand, the A / D conversion circuit 41 converts the image signal sent from the signal processing circuit 37 into digital data and inputs the digital data to the IC card 18. At this time, the memory control circuit 43 controls the writing of the IC card 18 according to the shutter ON signal from the shutter control circuit 34, and stores the image information output from the A / D conversion circuit 41 in the IC card 18.
[0017]
Thereafter, when the release switch 13 is pressed in the same manner, the image information captured at that time is recorded in the FD 17 and stored in the IC card 18.

Is read by the reproducing head 47b, amplified by the reproducing circuit 51, and then input to the demodulation circuit 52 to perform the demodulation operation. The signal demodulated by the demodulation circuit 52 is input to the encoder 53 and returned to the original luminance signal Y and color difference signals RY and BY and sent to the display control circuit 38 via the signal line c. The display control circuit 38 selects an image signal sent from the encoder 58 in accordance with an instruction from the control circuit 44 and displays the image signal on the finder 14 and the liquid crystal display panel 16.
