Abstract: The present invention provides a digital camera capable of optimizing a timing of switching a display screen to a print setting screen including an image on which print settings are to be made. In a process of protecting or formatting a captured image in a playback mode, a process of recording a captured image in an image capturing mode, and the like, a request of a file access (writing) to a memory card is generated. In response to the request or the like, a state where a file in the memory card is protected from other accesses is set, and writing of the file starts. After that, writing of the file is completed, and various accesses to the file in the memory card are permitted. That is, during a file access (writing), in response to depression of a print button, an operation of reading an image file in the memory card and switching to a print mode is inhibited.

Abstract: There is provided a controller capable of effectively using a camera in a TV telephone system and a technique related to the same.
