ABSTRACT:
Apparatus and a method for improving image quality in an image sensor, where a black level of a photographed image is calibrated and luminance of an image signal is expanded within the allowable range of luminance through knee correction for the image signal in which the black level is calibrated. Interpolation for restoring a dead pixel may be achieved before gamma correction for image signal.
