Abstract
An imaging apparatus amplifies signal voltage resulting from voltage conversion of signal charge obtained by photoelectric conversion of an optical image of an object and then performs digital conversion to the signal voltage. The imaging apparatus includes an amplifier circuit that amplifies the signal voltage using two or more amplification factors that are set, a weight determining unit configured to determine weights for the respective signals subjected to the digital conversion after the amplification based on the two or more amplification factors, and a combining unit configured to combine the two or more signals subjected to the digital conversion after the amplification using the weights.
