Image data is temporarily stored in the internal memory. The image data processing means 140 performs data compression processing when recording image data on an external recording medium. If the image data is a high-quality image and cannot be stored in one external recording medium, an entire image compression file is generated by compressing the entire image data, and the image data is stored in several parts. Generate a divided image data file. At this time, in the divided image data file, for example, a number or a character that clarifies the positional relationship with another divided image or the whole image may be set so as to clarify the position of the divided image data.

Byte y information and 1 byte cb for every 2 dots
It is assumed that information and cr information are assigned. When recording image data on the external recording medium 200, it is necessary to support a general image file format. Therefore, based on the y information, cb information, and cr information stored in the memory 132, one byte of r per dot is used.

According to the above procedure, recording processing on the external recording medium is performed. In the above description, the entire image compressed file is created each time recording to the FD is performed. However, if the entire image compressed file can be temporarily stored in the memory, the file need not be created every time. Further, although the entire image is recorded by dividing it into four parts, the number of divisions may be any number.

Next, a case of reproducing a high quality image will be described. First, a case where a digital camera reproduces a divided image of a high-quality image and an entire image for confirming the position of the divided image will be described. Returning to FIG.
