Abstract
An image signal processing apparatus includes an image signal input unit for inputting an image signal, a noise correcting unit for executing noise correction processing for the input image signal to output a noise-corrected image signal; an image signal correcting unit for executing signal level correction processing for the noise-corrected image signal to output a signal level-corrected image signal; an image signal correction intensity control unit for determining correction intensity of the signal level correction processing in the image signal correcting unit; a signal extension estimating unit for estimating a signal extension degree of signal extension based on the determined correction intensity; and a noise correction intensity control unit for calculating and controlling correction intensity of the noise correction processing in the noise correcting unit.
