Abstract

A printer-built-in image-sensing apparatus comprising a camera which performs image sensing with film exposure, and a printer which prints an image sensed by the camera. After a shutter button has been pressed and image sensing with strobe light emission has been performed, if printing is instructed by pressing of a print button, electric charge of a capacitor of a strobe circuit is made after the completion of print operation. Otherwise, the charging of the capacitor is started immediately after the image sensing. In this case, even if printing is instructed during the electric charge, printing is started after completion of the electric charge. Thus, electric consumption upon print operation can be reduced and fluctuation of voltage can be suppressed.

Claims

1. A printer-built-in image-sensing apparatus having a printer which prints an image on a print medium, comprising:

display means for displaying an image on a view finder;

instruction means for instructing printing of the image using said printer; and

control means for, if said instruction means instructs printing of the image, starting printing of the image by said printer and stopping power supply to said display means.

2. The printer-built-in image-sensing apparatus according to claim 1, further comprising information display means for displaying print status information during the printing of the image by said printer.

3. The printer-built-in image-sensing apparatus according to claim 1, wherein said control means turns off power supply to said display means when a film is rewind in a camera.

4. The printer-built-in image-sensing apparatus according to claim 1, wherein the camera is a video camera.

5. An electric-consumption control method in a printer-built-in image-sensing apparatus having a camera including a view finder which displays an image and a printer which prints an image, comprising:

a printing step of starting printing of an image by said printer if the printing of the image using said printer is instructed; and

a turn-off step of turning off power supply to the view finder during the printing of the image by said printer.

6. The electric-consumption control method according to claim 5, further comprising a display step of displaying information on printing of the image during the printing of the image by said printer.

7. The electric-consumption control method according to claim 5, further comprising a turn-off step of turning off the power supply to the view finder when a film is rewind in said camera.

8. The electric-consumption control method according to claim 5, wherein said camera is a video camera.
