An electronic endoscope apparatus has a moving-image displayer that reads image-pixel signals from an image sensor at predetermined time intervals to display a moving-image, a light-amount adjuster that adjusts an amount of light for illuminating a subject, and a still-image recorder that performs a series of actions for recording a still image. The still-image recorder is capable of reading the image-pixel signals at a still-image electronic shutter speed, which corresponds to a reading time interval shorter than the predetermined time interval. When the series of actions is started, the still-image recorder controls the light-amount adjuster such that the light-amount becomes a standard light-amount corresponding to the recording of the still image. Then, the still-image recorder performs a recording process in accordance with the still-image electronic shutter speed when the light-amount becomes the standard light-amount.
