The present invention provides an apparatus and corresponding method for reducing temporal noise of a target frame and enhancing the motion of the target frame. The apparatus includes a storage device, a temporal noise reducing circuit, and a motion enhancing circuit. The storage device stores a first filtered signal of a previous frame. The previous frame is previous to the target frame. The temporal noise reducing circuit reduces temporal noise of the target frame according to the first filtered signal and an image signal of the target frame. The temporal noise reducing circuit then generates a second filtered signal of the target frame, which is stored in the storage device. The motion enhancing circuit enhances the motion of the target frame according to the first and the second filtered signals, and generates a motion-enhanced signal of the target frame.
