Abstract
Either of two power off modes can be selected in a digital camera that reads out images from an image-capturing element, temporarily stores them in a buffer memory and then transfers and records the images from the buffer memory into a recording medium. In a first power off mode, the supply of stabilized power is stopped in response to a main switch off operation only after unrecorded images present in the buffer memory are all recorded into the recording medium. In a second power off mode, the supply of the stabilized power is stopped immediately in response to a main switch off operation regardless of whether or not there are yet-to-be recorded images present in the buffer memory. The power is cut off in conformance to the current power off mode setting when the main switch is turned off.
