Disclosed herein is an imaging apparatus including: a pixel section having a plurality of pixels arranged in two dimensions for effecting photoelectric conversion; a light blocking section for blocking light to conceal the pixel section in accordance with a light blocking instruction signal; a region setting section for outputting the light blocking instruction signal and setting a correcting pixel region from which pixel data for correction are extracted within an effective pixel region of the pixel section where an object image is formed; a line memory for retaining pixel data from the correcting pixel region at the time of blocking light; and a correcting section for correcting an output of pixel data from the pixel section using the pixel data retained at the line memory.
