Abstract
An image processing apparatus is provided which performs image processing of an input frame image. Contrast analyzer generates a histogram of the input frame image and calculates contrast based on the histogram. Motion-detecting threshold setter calculates a lower-limit threshold and an upper-limit threshold of a motion-detecting threshold by using an input-operated motion-detecting level and the calculated contrast. Motion detector determines that an observation pixel is moving considerably in a case where a finite difference value between frames is greater than the upper-limit threshold, and sets composite ratio K such that compositing of a preceding frame image is not performed. In a case where the finite difference value is smaller than the lower-limit threshold, the observation pixel is determined to be stationary, and composite ratio K is set such that compositing of the preceding frame image is performed at the maximum ratio.
