摘要： The output voltages of dark pixels and optical black (OB) pixels are different between a row including a pixel which receives strong light and another row. An image formed upon receiving a strong light spot suffers whitish bands on the right and left of the spot. To solve this problem, this invention provides an image pickup apparatus including a pixel containing a photodiode which converts a photo-signal into a signal charge and accumulates the signal charge and an amplifier transistor which amplifies the signal charge accumulated in the photodiode, and a control element adapted to limit the output of the amplifier transistor so as to prevent the output from falling to below a predetermined voltage.
