<p>PROBLEM TO BE SOLVED: To shorten the time required from a state of turning on a power supply to a prescribed operation state in an information processor such as an image pickup device. SOLUTION: When a storage medium is attached (substituted) in a power off-state (201), a system is started (202), storage medium information (a file name, residual capacity, etc.), is read out from the storage medium (203) and written in a backup memory (204) and the power-off state is restored (201). When the power supply is turned on, the system is started (205), the storage medium information is read out from the backup memory (206), an image pickup control program is started and the storage medium information is transferred to the program to turn the system to a photographing enabled state (207).</p> |
