Patent ID: 7557837

Claim:
An image pickup apparatus comprising: an image pickup unit; an image processing unit configured to process an image signal obtained by the image pickup unit; a recording unit configured to record the image signal that is outputted from the image processing unit; a display unit configured to display on an electronic viewfinder screen an image based on the image signal that is picked up by the image pickup unit and outputted from the image processing unit; a color determination unit configured to determine a color value based on color information included in a predetermined region of an image that is being displayed on the electronic viewfinder screen; and a color conversion parameter determination unit configured to determine color conversion parameters for leaving the color value determined by the color determination unit and converting a color component value included in the image signal other than the color value into a predetermined color value, wherein the image signal is processed by the image processing unit based on the parameters determined by the color conversion parameter determination unit and the processed image is displayed by the display unit, and wherein the color conversion parameter determination unit determines color conversion parameters for converting a U value and a V value of each lattice point other than a lattice point corresponding to the color value or lattice points in the vicinity of the color value, among lattice points that are set within a YUV color space, into zero.
