Abstract:
1. An image pick-up apparatus, comprising: an image pick-up lens; an image pickup unit configured to convert image light having passed through said image pick-up lens into an electrical picture signal; a first camera signal processing unit configured to process said picture signal without any change from a primary color signal at a time of image pick-up; a first resolution conversion unit configured to perform a magnification or reduction of a picture on each color of said primary color signal at the time of said image pick-up with respect to an output signal from said first camera signal processing unit; a detection unit provided in said image pick-up lens configured to detect a drive state of an iris diaphragm and a lens image height of a subject; a control unit configured to control a conversion factor and a coordinate of the center of light axis for performing the magnification or reduction in said first resolution conversion unit in accordance with a detected output from said detection unit; a second camera signal processing unit configured to convert an output signal from said first resolution conversion unit into a video signal; a primary color filter including a color separating unit of arbitrary three colors or more corresponding to each pixel in said image pickup unit; data memory unit in which chromatic aberration data specific to said image pick-up lens is stored for each color of said primary color filter; and a computing unit configured to compute a control parameter which controls the conversion factor and the coordinate of the center of light axis for performing said magnification or reduction in said control unit using said chromatic aberration data stored in said data memory unit and the detected output from said detection unit.
