A solid-state image sensor able to adjust sensitivity in a wide range without causing flicker or stripes, even when the illumination source is a fluorescent lamp, has been disclosed. The solid-state image sensor comprises: plural pixels and; a gain variable amplifier that amplifies signals sequentially read from the plural pixels at a fixed cycle time and the amplification factor of which can be varied, and the storage time of the pixel can be set to an arbitrary value, wherein the sensor comprises: a brightness/illumination flicker detection section; and a control section that varies the storage time step by step to one of plural flicker-less times in accordance with the detected brightness and the illumination flicker as well as varying the amplification factor of the amplifier in accordance with the detected brightness and the storage time.
