An image-taking apparatus includes: an A/D conversion circuit having an amplifier that is capable of amplifying image signals per shooting frame; and a gain changer that changes the gain of the amplifier. The apparatus causes the gain changer to increase the gain of the amplifier up to a level that compensates for a gradual decrease in the amount of light emitted from LEDs that occurs during continuous shooting. As a result, the amplitude level of every image signal is made constant and thus, replayed images of the same brightness shot during the continuous shooting are obtained.
