A control system for an image file eliminating saving of an overlapped image data part and saving files in a short time and in a power-saving manner. When a digital camera and a personal computer are connected with each other for data communication, the system compares record unit information to identify an image file that the digital camera has with record unit information to identify an image file that the personal computer has, and transfers to save the image file, which includes the record unit information that the digital camera has and the personal computer does not have, from the digital camera to the personal computer. After completing transfer of the image file from the digital camera to the personal computer, the personal computer generates record unit information newer than the record unit information of the acquired image file and transmits the newer record unit information to the digital camera, which can be recorded in the header of the image file newly photographed by the digital camera.

A processor which is switchable between a first execution mode (such as a scalar mode) and a second execution mode (such as a VLIW mode) is disclosed. The processor has a first processor context when in the first execution mode and a second processor context, different from the first processor context, when in the second execution mode. The processor generates an exception when the processor attempts to change from one execution mode to the other.
