Patent ID: 6897895

Claim:
A digital camera, comprising: an imaging device for imaging a subject and outputting first image data having a first resolution; a generator for generating second image data having a second resolution which is lower than the first resolution based on the first image data outputted from said imaging device; and a writer for intermittently writing to a first memory the first image data outputted from said imaging device, and writing the second image data generated by said generator to said first memory at intervals of writing of the first image data, wherein said imaging device outputs the first image data in a raster scan manner, and said writer writes the second image data to said first memory during a horizontal blanking period of the first image data; wherein the first image data has horizontal lines of a first number, the second image data has horizontal lines of a second number which is smaller than the first number, and said writer writes to said first memory, at every time the first image data corresponding to horizontal lines of a third number which is smaller than the first number is written to said first memory, the second image data corresponding to horizontal lines of a fourth number which is smaller than the second number.
