Abstract: Provided is a digital camera which displays an object image while generating a digital image signal from light received from the object, stores the digital image signal in a memory card attachable to the camera, and reproduces a start information signal, which is set up by the user, preferably at the point of time when power is applied. The digital camera further includes a flash memory. Sound recording data inputted by the user, image data stored in the memory card, sound recording data stored in the flash memory, or image data stored in the flash memory can be set up as a start information signal, and data regarding the set-up of start information signal is stored in the flash memory.

Abstract: A power supply having a stable reset function a mobile electronic unit is provided that simultaneously resets the digital signal processing unit and the controller in a mobile electronic unit. The stable reset function occurs during the period of time when the power source of the mobile electronic unit is changed by removing an AC adapter from the mobile electronic unit and applying the power source of the battery which was previously installed in the mobile electronic unit.

Abstract: Provided is a method of controlling a digital photographing apparatus by which user files obtained as a result of performing a photographing operation in a photographing mode are stored in a storage medium and reproduced in a reproducing mode.
