Abstract:
An image processing apparatus can perform time-sequential weighting addition processing on a moving image constituted by a plurality of frames includes a filter unit configured to obtain an image by performing recursive filter processing on a frame image that precedes a present target frame, which is one of the plurality of frames constituting the moving image, a coefficient acquisition unit configured to acquire a weighting coefficient for the present target frame based on a noise statistic of a differential image between an image of the present target frame and the image obtained by the filter unit, and an addition unit configured to perform addition processing on the moving image constituted by the plurality of frames based on weighting coefficients acquired by the coefficient acquisition unit.
