Abstract
An imaging apparatus includes: pixels (); signal lines each arranged correspondingly to each of columns of the plurality of pixels; a row scanning circuit () selecting the plurality of pixels row by row for outputting signals to the plurality of signal lines; and a first gain correcting circuit () correcting the signals in the plurality of signal lines by applying a gain to the signals so as to reduce a difference of a signal value due to the difference of the charge accumulation period between a first row and a second row, when a pixel region selected for reading out in a present frame is different from a pixel region selected for reading out in a previous frame so that a charge accumulation period of the first row of the plurality of pixels is different from a charge accumulation period of the second row of the plurality of pixels.
