Abstract: In an image processing apparatus, information indicating a degree of correlation between a current frame and a previous frame is computed based on a pixel value in the current frame before being subjected to the recursive noise reduction and a pixel value in the previous frame after being subjected to the recursive noise reduction. Then, a recursive coefficient, which is a weight of the previous frame, is determined based on the degree of correlation and a frame rate of the moving image. The recursive noise reduction is applied to the current frame by combining the pixels in the previous frame and the current frame using the recursive coefficient. For the same degree of the correlation, the recursive coefficient is determined to be smaller as the frame rate is lower. Noise reduction in accordance with the image frame rate is achieved.
