More Information
Summary:The movement of an image between the image information of a current frame and the image information of a frame which is one, two, or three frames prior to the current frame is detected. On the basis of the detection result, a noise reducing process is performed. Moreover, identity between the pixel information of the current frame about a pixel which is currently the target of the process and the pixel information of the current frame or the frame which is one, two, or three frames prior to the current frame about a plurality of pixels located near the target pixel is detected. On the basis of the detection result, the noise reducing process is performed.
