    摘要: An image data processing method is provided. In this method, a plurality of original pixel values of an image is input. An interpolation position of a target pixel in the image is determined. Whether the interpolation position is in a central region of an object or in a marginal region of an object is determined. A pixel value interpolation with respect to the interpolation position is performed. When the interpolation position is in the central region of an object, the pixel value interpolation is performed in a first calculation mode, and when the interpolation position is in the marginal region of an object, the pixel value interpolation is performed in a second calculation mode, wherein the first calculation mode may be a low pass filtering interpolation mode, and the second calculation mode may be a linear interpolation mode.

    摘要: The present invention discloses a method for compressing and decompressing pixel data and the device thereof. The method comprises receiving current pixel data from a preprocessor and comparing the current pixel data with predictor pixel data to obtain a section index from a quantization table. Output the section index to a memory as compressed data. Then, receive the compressed data from the memory. Use the quantization table to look up a representative level corresponding to the compressed data and output decompressed pixel data based on the representative level to an image processing unit. The device mentioned above comprises a memory, a compressor and a decompressor. The memory stores compressed data. The compressor quantizes and compresses pixel data and outputs the compressed pixel data to the memory. The decompressor receives the compressed pixel data and decompresses the compressed pixel data and outputs the decompressed pixel data as pixel data.
