IMAGING APPARATUS, METHOD FOR DRIVING IMAGING APPARATUS, IMAGING SYSTEM, AND DRIVING METHOD FOR IMAGING SYSTEM

摘要

An imaging apparatus includes: pixels (1); signal lines each arranged correspondingly to each of columns of the plurality of pixels; a row scanning circuit (2) selecting the plurality of pixels row by row for outputting signals to the plurality of signal lines; and a first gain correcting circuit (6) 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.

1. An imaging apparatus comprising:
a plurality of pixels arranged in a matrix, each pixel accumulating an electric charge based on an incident light quantity; a plurality of signal lines each arranged correspondingly to each of columns of the plurality of pixels; a row scanning circuit configured to select the plurality of pixels row by row for outputting signals from the plurality of pixels to the plurality of signal lines; and a first gain correcting circuit configured to correct the signals in the plurality of signal lines by applying a gain to the signals, wherein, 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 a first row of the plurality of pixels is different from a charge accumulation period of a second row of the plurality of pixels, the first gain correcting circuit corrects the signals to reduce a difference of a signal value due to the difference of the charge accumulation period between the first row and the second row.
