Abstract:
1. An image pickup device comprising: an optical system; an image sensor; an AGC circuit; a magnification chromatic aberration correction unit configured to perform magnification chromatic aberration correction on image data; an MTF correction unit configured to perform an MTF correction process on an output of the magnification chromatic aberration correction unit; a skew aberration correction unit configured to perform skew aberration correction on an output of the magnification chromatic aberration correction unit or the MTF correction unit; a control unit configured to control the MTF correction unit so as not to perform the MTF correction process in the event that the control unit determines that illuminance of the image data is low based on information which directly or indirectly indicates the illuminance; and a switch circuit configured to provide a first connection between the MTF correction unit and the skew aberration correction unit or a second connection between the magnification chromatic aberration correction unit and the skew aberration correction unit, the second connection bypassing the MTF correction unit, the switch circuit configured to receive a signal for switching off the MTF correction unit from the control unit and to transfer the output of the magnification chromatic aberration correction unit to the skew aberration correction unit via the second connection.
