Abstract

A printer-built-in image-sensing apparatus including 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, then electric charging a capacitor of a strobe circuit is made after the completion of the 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. An image sensing apparatus for supplying image data to a printer so as to print an image, comprising:

a display unit configured to display an image on a screen;

an instruction unit configured to instruct to print the image using the printer;

a display configured to display print status information; and

a control circuit configured to cause the printer to print the image in a case where said instruction unit instructs to print the image, and to cause said display unit not to display the image on the screen during print operation by the printer and cause said display to display the print status information while the printer is printing the image.

2. The apparatus according to claim 1, wherein said control circuit turns off display unit in order to stop displaying of the image on the screen.

3. The apparatus according to claim 1, wherein the image sensing apparatus incorporates the printer.

4. A control method for controlling an image sensing apparatus having a display unit comprising:

a step of displaying an image on a screen of the display unit;

an instruction step of instructing a printer to print the image; and

a control step of controlling printing of the image by the printer and causing the display unit not to display the image on the screen during print operation instructed in said instruction step, and displaying print status information on a display while the printer is printing the image.

5. The method according to claim 4, wherein in said control step, the display unit is turned off in order to stop displaying of the image on the screen.

6. The method according to claim 4, wherein the image sensing apparatus incorporates the printer.

7. A computer readable medium for storing programs for carrying out the control method according to claim 4.
