Abstract: To solve the problem that an existing image noise rejection technique is designed to flatten one or two or more regions of an image signal, which sometimes results in a stepwise artifact formed in the image signal.SOLUTION: An image processing device and method for reducing or removing a stepwise artifact includes an image sensor and a circuit. The image sensor is constituted so as to latch an input image signal. The circuit is constituted so as to identify a first portion of the input image signal that indicates a stepwise artifact. The circuit is further constituted so as to generate an inclination signal on the basis of a steepness parameter of inclination corresponding to a first interest region on the basis of this identification. The circuit is constituted so as to generate a difference signal on the basis of a difference between the first portion of the input image signal and the generated inclination signal. The circuit is constituted so as to generate a noise rejection image signal on the basis of the difference signal generated in order to reduce the stepwise artifact in the first portion of the input image signal and the generated inclination signal.SELECTED DRAWING: None
