Abstract:
1. An imaging apparatus comprising: a pixel unit including an effective pixel region of a plurality of pixels, and an ineffective pixel region of a plurality of pixels; a plurality of vertical signal lines; a vertical scanning circuit for selecting row by row, or rows by rows, the pixels of the pixel unit, such that signals of the selected pixels are outputted to the plurality of vertical signal lines; and a correction circuit for correcting a signal of a pixel in the effective pixel region based on the signal of the pixel selected at plural times and outputted, wherein the ineffective pixel region includes first and second ineffective pixel regions of mutually different rows, the vertical scanning circuit selects at plural times pixels of a same row of the second ineffective pixel region during one frame time period, and selects at one time pixels of a same row of the first ineffective pixel region during the one frame time period, and the correction circuit includes a first correction circuit for averaging signals of the pixels in the first and second ineffective pixel regions selected at a first time and correcting signals of the pixels in the effective pixel region, and a second correction circuit for averaging signals of the pixels in the second ineffective pixel region selected at a second time and following times and correcting the signals of the pixels in the effective pixel region.
