摘要: According to one embodiment, a third optical black portion is arranged in parallel with a first optical black portion in a row direction and in parallel with a second optical black portion in column direction. At least one of the vertical line correction circuit and the horizontal line correction circuit adds/subtracts arithmetic average of the third black level signal generated by the third optical black portion.
