Abstract:
An image processing apparatus includes a noise level calculation circuit, an inter-frame change amount calculation circuit, a recursive coefficient calculation circuit, and a composite processing circuit. The noise level calculation circuit detects a noise level of a signal of a focused frame in moving images. The inter-frame change amount calculation circuit detects the amount of change between the focused frame and the previous frame by using the noise level of the focused frame, the signal of the focused frame, and a signal of the previous frame after a noise reduction process. The recursive coefficient calculation circuit sets a coefficient for use in the noise reduction process according to the amount of change. The composite processing circuit performs the noise reduction process on the signal of the focused frame by using the signal of the focused frame, the signal of the previous frame after the noise reduction process, and the coefficient.

Claim (Index 7):
The image processing apparatus according to  claim 6 , wherein\n the change amount detection circuit includes: a component-based detection circuit configured to detect the amounts of change for the individual components; a selection circuit configured to select one of a plurality of modes based on comparison between the noise levels of the individual components detected by the detection circuit and at least two thresholds; and a calculation circuit configured to calculate mode-based amount of change in the selected mode, by using the amounts of change of the individual components detected by the component-based detection circuit and the noise levels of the individual components calculated by the detection circuit, wherein the coefficient calculation circuit sets the coefficient in accordance with the mode-based amount of change.
