ABSTRACT:
An image processing apparatus comprises a number of times of integration determiner for determining a number of times of integration based on stop information representing a stop value of an image pickup unit for picking up a still object, and an integrator for integrating the still image data produced by the image pickup unit by the number of times determined by the determiner. The apparatus modifies the still image data integrated by the integrator for each integration in accordance with the current number of times of integration and the stop information. In another aspect of the invention, the apparatus comprises a calculator for sequentially and circulatively adding K times (0<K<1) of an input video signal and (1-K) times of a past image signal correlated to the input video signal to reduce a noise component of a still image or a still image area in a motion picture. The apparatus modifies the coefficient K in accordance with an elapsed time from the start of the noise reduction operation at an interval of unit period in which the video signals are correlated to each other or an interval which is an integer multiple of the unit period.
