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.
