A digital camera includes a CCD imager which outputs 640 pixelsx480 lines of camera signal in a raster scan scheme. The camera signal outputted from the CCD imager is subjected to a predetermined signal processing whereby created are 640 pixelsx480 lines of original image data and 80 pixelsx60 lines of thumbnail image data. Both the created original image data and thumbnail image data are written to a SDRAM. The writing of the thumbnail image data is performed during a horizontal blanking period of the original image data. As a result, image data writing operation completes within a 1-frame period of time.
