When setting the photographing mode, as shown in FIG. 4, first, the operation switch 214c is operated to the "REC" position, and by this operation, the system controller 215 shoots the input operation of each of the operation switches 214a and 214b. Accepted as an input operation in mode. Here, for example, when the operation switch 214a is pressed, the focusing mode is switched. When the current mode is the automatic focusing mode M11, switching from the automatic focusing mode M11 to the manual focusing mode M12 is performed. When the current mode is the manual focusing mode M12, the switching from the manual focusing mode M12 is performed. Switching to the automatic focusing mode M11 is performed. When the manual focusing mode M12 is set, the operation switch 214a functions as a focus position adjustment switch by rotating the operation switch 214a. When the operation switch 214a is rotated to the right, for example, the in-focus position of the lens 201 is adjusted to the near side, that is, the short distance side by a distance corresponding to the amount of rotation of the operation switch 214a to the right (M16). On the other hand, when the operation switch 214a is rotated leftward, the focus position of the lens 201 is adjusted to the far side by a distance corresponding to the leftward rotation amount of the operation switch 214a (M15). When the automatic focusing mode M11 is set, the rotation operation of the operation switch 214a is invalidated.

When the operation switch 214b is pressed while the photographing mode is set, the exposure mode is switched. When the current mode is the automatic exposure mode M13, the automatic exposure mode M13 is switched to the manual exposure mode M1.

Here, each time the operation switch 214a is pressed, the normal playback mode M21 and the playback still mode M22 are alternately switched. When the reproduction still mode M22 is set, the operation switch 214a functions as a switch for frame-forwarding the reproduced image by one frame by rotating the operation switch 214a. For example, the operation switch 214a is moved rightward by 1/16
Each time the rotation operation is performed, the reproduced image is sequentially sent in the forward direction of the recording medium 208 in units of one frame (M26). On the other hand, every time the operation switch 214a is operated 1/16 of a left turn, the reproduced image is recorded on the recording medium 2 in one frame unit.

A subcode indicating that the recorded content is a still image is recorded in the subcode. When a still image recorded on the recording medium 208 is reproduced in the still image recording mode, the still image reproduction mode is set in the reproduction mode state as shown in FIG. When the still image playback mode is set, the operation switch 214b functions as a switch for retrieving and displaying a recorded still image. Specifically, when the operation switch 214b is rotated rightward, the system controller 215 performs a count-up operation in which 1/16 rotation amount of the operation switch 214b rightward is set as one unit (M24). Next, when the operation switch 214b is pressed, the count-up operation is stopped. The count value when the count-up operation is stopped is a value for designating the position of the next still image to be displayed. The recording medium 208 is sent to a position corresponding to this value, and the still image at this position is reproduced. It is displayed (M27). Similarly, when the operation switch 214b is rotated leftward, a countdown operation is performed in which 1/16 rotation amount of the operation switch 214b leftward is set as one unit (M25), and the operation switch 214b is pushed. As a result, the recording medium 208 is sent to a position corresponding to the count value at the time of stopping the countdown operation, and the still image at this position is reproduced and displayed (M27).

For example, as shown in FIG.
8 with the reproduction position at the point A.
When the still image recorded in the still image marker is reproduced, the operation switch 214b is operated to the left by 3/16 turn, and when the operation switch 214b is subsequently pushed, the count value by the countdown operation becomes "-3" and the still image marker The recording medium 208 is sent so that the position where (2) is recorded becomes the reproduction position, and the still image (2) is reproduced. Further, when the operation switch 214b is operated to the right by 2/16 turn in the state where the reproduction position is at the point A, and then pressed, the count value by the count-up operation becomes “+2” and the still image marker ( The recording medium 208 is sent so that the position where (6) is recorded becomes the reproduction position, and the still image (6) is reproduced.

As described above, in the present embodiment, the input operation in the photographing mode and the reproduction mode is set so as to be performed by combining the pressing operation and the rotating operation of each of the operation switches 214a and 214b. Input operations for many functions can be performed with the operation switches 214a and 214b, and it is possible to prevent a reduction in the size and weight of the device due to the large number of operation switches.
