PROBLEM TO BE SOLVED: To provide an imaging device capable of setting up an amplification rate for each of photographed pixel signals and obtaining a proper photographed image. SOLUTION: An analog front end apparatus 4 comprises a first CDS circuit 41a to a sixth CDS circuit 41f for performing processing including CDS processing for a signal for each pixel constituting an analog image array signal, a single column conversion circuit 42 for selecting and outputting an output signal from each of CDS circuits 41a-41f to output one-column output signals, an AD conversion circuit 46 for converting the analog image array signal into a digital image signal, and an amplification rate storage apparatus 43 in which an amplification rate corresponding to each of pixel signals constituting the analog image array signal is stored. Using an amplification rate corresponding to each pixel signal and stored in the amplification rate storage apparatus 43, each of the CDS circuits 41a-41f performs signal amplification processing for each pixel signal constituting an analog image array signal, in addition to original CDS processing.
