Abstract:
1. An image pickup system comprising: an image pickup element including an image pickup region in which a plurality of pixels are arranged in a matrix; and a controller configured to control reading of signals from the plurality of pixels, wherein the controller divides a first frame period, in which a first image is read from the image pickup element, into a plurality of divided frame periods including first and second divided frame periods, wherein, when a number of pixels included in the first image is larger than a number of pixels included in a second image, a second frame period required for reading all signals from the pixels included in the second image is inserted between the first and second divided frame periods, wherein a refresh cycle of the second image is shorter than a refresh cycle of the first image, and wherein, when the first divided frame period is shorter than the second divided frame period, the controller adds a waiting time to the first divided frame period so that a sum of the first divided frame period and the waiting time is equal to the second divided frame period.
