Patent ID: 8654257

Claim:
An image processing apparatus comprising: an image signal input unit that receives an input of an image signal representing frame images to be displayed; a noise reduction unit that performs noise reduction for reducing the noise contained in the image signal, the noise reduction utilizing an interframe averaging operation that is performed on a frame image to be processed using a frame image precedent to the frame image to be processed; an image quality adjustment unit that performs image quality adjustment for adjusting the displayed image quality of a frame image on the image signal that has undergone the noise reduction; and a control unit that controls the setting of an image quality adjustment parameter that defines the amount of adjustment in the image quality adjustment operation and the setting of a noise reduction parameter that defines the amount of noise reduction in the noise reduction operation, wherein: when the image quality adjustment parameter is changed, the control unit changes the setting of the noise reduction parameter to prevent the increase in noise in association with the change in the image quality adjustment parameter, and an amount of change in the noise reduction parameter is used to calculate a weight factor utilized in the interframe averaging operation.
