ABSTRACT:
Image signals of all the pixels of a non-interlace scanning type image sensing device are sequentially outputted by a plurality of output terminals in one field period, the outputted image signals are amplified by a plurality of amplifiers each of which is provided for each of the output terminal, then the amplified signal levels of the image signals are detected by a detector. Gains to be used in the plurality of amplifiers are corrected on the basis of the signal levels detected by the detector and correction data for correcting difference in signal level of the image signals amplified by identical gains by the plurality of amplifiers, thereby correcting a variation in characteristics of the plurality of amplifiers.
