Abstract
A signal processing apparatus to be used for a solid-state image pickup element having a plurality of output systems that output video signals obtained from pixels arranged in a column direction includes a subtraction unit that subtracts an amended error value for each column from the video signals output from the solid-state image pickup element. The signal processing apparatus also includes an error value computing unit that shields the solid-state image pickup element from light or irradiates light to the solid-state image pickup element at a constant rate, computes a respective average value of each of a plurality of pixel signals obtained from the pixels in a predetermined region of the solid-state image pickup element, subtracts the respective average value from a respective of the plurality of the pixel signals obtained from the pixels of the solid-state image pickup element, and accumulates values obtained by subtractions for respective columns.
