Abstract

An image processing apparatus is applied to a display and includes a sampling unit, a comparing unit, a determining unit and an operating unit. The sampling unit is configured to receive a pulse-width modulation (PWM) signal and sample the PWM signal to output a current image. The comparing unit is coupled to the sampling unit and configured to compare the current image with a previous image to generate a comparison result, wherein the previous image is prior to the current image. The determining unit is coupled to the comparing unit and configured to determine whether the current image is the same with the previous image according to the comparison result and a threshold value. If a determination result of the determining unit is YES, the operating unit stops its operation.
