Abstract: A data slicer includes an error bit predictor, a DC level compensator, a co-channel detector, and an output device. The data slicer generates four bytes according to four slicing levels respectively. The four slicing levels are a DC level, a level generated by adding a predetermined offset to the DC level, a level generated by subtracting the predetermined offset from the DC level, and a compensated level generated by the DC level compensator. The co-channel detector determines if the compensated level has the co-channel interference. The output device generates an output byte according to indication signals generated by the co-channel detector and the error bit predictor and the parity check of the four bytes.

Abstract: An image processing method and device thereof are provided. The device includes a capture device and a processor. The capture device is adopted for receiving a plurality of frames and comparing at least two adjacent frames to obtain an area selection signal according to a differential value there-between. The processor is connected to the capture device for receiving the area selection signal and to separate each of the adjacent frames into at least two areas. Each of the areas of the adjacent frames is performed by an image processing step respectively, and then the images of the areas are combined to obtain a resulted frame.
