ABSTRACT:
A mobile communication terminal comprises a camera unit (34) and a main CPU. In the camera unit (34), a processing system including a color conversion circuit (66) and an image compression circuit (68) generates high-resolution compressed still image data based on interpolated image data of a photographed object. Also, a processing system including an image decompression circuit (74), a color conversion circuit (72), and a thinning-out circuit (70) generates low-resolution decompressed still image data based on the high-resolution compressed still image data. The main CPU activates an image compression circuit (68) when a release key is operated, and activates an image decompression circuit (74) when generation of the compressed still image data is completed. The low-resolution decompressed image data generated by activation of the image decompression circuit (74) is obtained by the main CPU from the camera unit and written into a VRAM. As a result, a decompressed image is displayed on an LCD.
