PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of expanding a dynamic range and performing signal processing in accordance with the gain of an amplifier in a simple configuration. SOLUTION: The imaging apparatus includes: one pixel (121) for generating a pixel signal by photoelectric conversion; an amplifying unit (122) which amplifies the pixel signal generated by the one pixel with a plurality of gains and outputs a plurality of pixel signals corresponding to the plurality of gains; a synthesizing unit (124) which selects one of the plurality of pixel signals output by the amplifying unit in accordance with the magnitude of the pixel signal output by the amplifying unit and outputs a signal based on the selected pixel signal; and a signal processing unit (130) which performs signal processing on the signal output by the synthesizing unit in accordance with the gain of the amplifying unit corresponding to the pixel signal selected by the synthesizing unit.
