Abstract

In a digital still camera, when the reproducing mode is selected, an indication to the effect that the operation is in standby for reproduction is displayed on an indicating device, and if the command dial is not operated until 16 seconds elapses after the indication has been started, the supply of source voltage to the various parts of the camera is stopped, to achieve a reduction in power consumption. If the command dial is operated within 16 seconds, image signals are output to an external monitor and also an indication to the effect that reproduction is in progress is displayed on the indicating device. If the command dial has been operated within three minutes after reproduction of a given photographic frame has been started, reproduction of the following frame is performed, but if the command dial has not been operated until the three minutes have elapsed, the indication to the effect that the operation is in standby for reproduction is displayed again. If the sensitivity changeover switch and the command dial are operated together during reproduction or standby for reproduction, the photographic frame to be reproduced is determined in correspondence to the quantity and direction of the rotation of the command dial and the frame number of the frame thus determined is displayed on the indicating device.

Claims

1. An electronic still camera, comprising:

an imaging device that outputs image data relating to a photographed subject image,

a recording device that converts the image data to compressed digital data and records the compressed digital data to a recording medium that exists within the camera,

a signal processing method selecting operation device that outputs a control signal to select one signal processing method, from among multiple signal processing methods including at least an NTSC method and a PAL method, as a signal processing method when the compressed digital data is output to an external monitor from the camera,

an output circuit that converts the compressed digital data recorded by the recording device to a video signal corresponding to the signal processing method that corresponds to the control signal, and outputs the video signal to the external monitor,

a display device that displays an established shooting condition, and

a display control circuit that displays the shooting condition during shooting and controls the display device so that the currently selected signal processing method, instead of the shooting condition, is identifiably displayed when the selecting operation of the signal processing method by the signal processing method selecting operation device takes place during non-shooting.

2. The electronic still camera according to claim 1, wherein

the display control circuit controls the display device so that a first display that displays the shooting condition and a second display that displays the signal processing method are displayed in a same position in a different manner.

3. The electronic still camera according to claim 1, wherein

the display control circuit controls the display device so as to display the signal processing method while the signal processing method selecting operation takes place.

4. The electronic still camera according to claim 2, wherein

the display control circuit controls the display device so as to display the signal processing method while the signal processing method selecting operation takes place.

5. The electronic still camera according to claim 1, wherein

the shooting condition is established by an operation of the signal processing method selecting operation device.

6. The electronic still camera according to claim 2, wherein

the shooting condition is established by an operation of the signal processing method selecting operation device.

7. The electronic still camera according to claim 3, wherein

the shooting condition is established by an operation of the signal processing method selecting operation device.

8. The electronic still camera according to claim 1, wherein

the recording medium is a memory card capable of recording multiple compressed digital data.

9. The electronic still camera according to claim 2, wherein

the recording medium is a memory card capable of recording multiple compressed digital data.

10. The electronic still camera according to claim 3, wherein

the recording medium is a memory card capable of recording multiple compressed digital data.

11. The electronic still camera according to claim 5, wherein

the recording medium is a memory card capable of recording multiple compressed digital data.

12. The electronic still camera according to claim 1, wherein

the output circuit outputs the video signal along with a corresponding frame number.

13. The electronic still camera according to claim 2, wherein

the output circuit outputs the video signal along with a corresponding frame number.

14. The electronic still camera according to claim 3, wherein

the output circuit outputs the video signal along with a corresponding frame number.

15. The electronic still camera according to claim 5, wherein

the output circuit outputs the video signal along with a corresponding frame number.

16. The electronic still camera according to claim 8, wherein

the output circuit outputs the video signal along with a corresponding frame number.
