Abstract:
A camera, comprising:a photographing element for converting image information into electric signals and for outputting image data; a memory mounting section on which a memory is mounted; control means for instructing writing the image data in the memory; accessing detecting means for detecting a condition that the memory is accessed and for outputting an accessing detecting signal; demounting detecting means for detecting a condition that the memory is being demounted from the memory mounting section and for outputting a demounting detecting signal; and accessing interrupting means for interrupting processes when a current process unit of a plurality of process units is completed in response to the demounting detecting signal, wherein the memory is accessed to carry out the processes by implementing the plurality of process units in sequence, wherein the memory is a flash memory in which invalid data are generated when the data are rewritten and the control means conducts an erasing process to create empty region by erasing the invalid data for each erasing block unit, and wherein when the erasing process is conducted for a current erasing block unit when the demounting detecting means outputs the demounting detecting signal, the accessing interrupting means interrupts the erasing process when the erasing process for the current erasing block unit is completed.
