A movement detection circuit (45) analyzes image data from a DSP (40), and detects an amount of movement of an obj ect relative to a solid-state image sensor (23). A CPU (41) compares a movement detection value with a threshold value. When the movement detection value is the threshold value or less, a normal light source (50) and a special light source (51) are alternately turned on and off at intervals of charge accumulation time of the solid-state image sensor. Normal light moving images (P1) and special light moving images (P2) are simultaneously displayed on a screen (17). When the movement detection value exceeds the threshold value, write of the special light moving images is inhibited. A display control circuit (46) displays on the screen one of the normal light moving images, a special light still image (P2'), and tiled windows for simultaneously showing the normal light moving images and special light still image.
