发明名称 Imaging apparatus and its control method for setting suitable clipping level
摘要 An imaging apparatus includes a plurality of photoelectric conversion units configured to output an image signal obtained by executing photoelectric conversion and a noise signal; a clipping unit configured to clip the noise signal to a clipping level when the noise signal exceeds a preset clipping level; a control unit configured to calculate the clipping level based on a signal read from the plurality of photoelectric conversion units and set the calculated clipping level to the clipping unit as the preset clipping level; and a differential unit configured to execute differential processing of subtracting a noise signal read from the photoelectric conversion unit and clipped by the clipping unit, from an image signal read from the plurality of the photoelectric conversion units.
