Abstract
This invention makes it possible to increase the image processing speed and reduce the power consumption at the same time by controlling power supply to each processing circuit with a simple control arrangement. To achieve this, when displaying or recording a captured image, a plurality of processing circuits are allowed to equally access a DRAM. When a captured image is displayed to be confirmed in a non-recording mode, power is supplied to an image developing unit with high power consumption in one of two sections obtained by dividing a display frame interval so as to concentrate memory access in the section, and power supply to the image developing unit is stopped upon the end of processing.
