The number of correction pixels necessary for removal of noise is reduced. A solid-state image pickup apparatus includes a pixel array unit in which image signal generation pixels for generating analog image signals in response to light irradiated thereupon and correction signal generation pixels for generating analog correction signals for correcting the image signals are arranged in a matrix pattern. A conversion unit performs first conversion that is conversion from the analog image signals generated by the image signal generation pixels arranged in a row in the matrix pattern into digital image signals. The conversion unit further performs second conversion, which is conversion performed at substantially the same time with the first conversion, from the analog correction signals generated by the correction signal generation pixels arranged in a plurality of rows in the matrix pattern into digital correction signals. A correction unit performs correction of the digital image signals with the digital correction signals generated in the plurality of rows.
