Publication number: 20050212915Abstract: 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.Type: ApplicationFiled: December 9, 2004Publication date: September 29, 2005Inventors: Toshihiko Karasaki, Hitoshi Hagimori, Yong Xin Huang, Masahito Niikawa

Publication number: 20050212943Abstract: The digital camera has an LCD and a print button and can set image capturing modes such as a single frame shooting mode and a continuous shooting mode. In the case where the print button is depressed in a state where the digital camera is set in the single frame shooting mode, after making an error check, the digital camera immediately shifts to a state where a print mode is set. In the print mode, a print setting screen in which settings of a print order can be made on an image recorded on a memory card is displayed on the LCD. As a result, settings of the print order can be made promptly.Type: ApplicationFiled: December 9, 2004Publication date: September 29, 2005Inventors: Toshihiko Karasaki, Hitoshi Hagimori, Yong Huang, Masahito Niikawa
