Abstract
An image processing method includes: receiving a currently-input image frame and a previously-output image frame; comparing multiple first pixels corresponding to coordinates of the currently-input image frame with multiple second pixels corresponding to coordinates of the previously-output image frame, and obtaining multiple corresponding differences; obtaining multiple dynamic parameter values based on the differences and a dynamic parameter table; obtaining multiple boundary retention values based on the dynamic parameter values and a boundary operator; and obtaining multiple currently-output pixels based on the first pixels, the second pixels, and the boundary retention values. An image processing apparatus performs the image processing method, to increase accuracy of identifying a boundary adjoining a motion region and a non-motion region, and to remove an artifact of the boundary.
