In order to obtain a digital still camera capable of storing only a desired image from photography images, a photography image data generation unit processes an image signal from a CCD to generate high-, middle-, and low-resolution image data. While a photography timing designation button is not depressed, the middle-resolution data is monitored in Dl of a display through a buffer memory. When the photography timing designation button is depressed, high- and low-resolution data of three consecutive frames are generated and stored in M2 to M7 of the buffer memory, and low-resolution data are displayed in D2 to D4 of the display. The high-resolution data are compressed and encoded, and then stored in CI to C3 of a main memory. When the user selects, e.g., D3 of the displayed D2 to D4 with a touch panel, the corresponding data of C2 is extracted from CI to C3 and stored in Fl of a nonvolatile memory.
