Lossless image compression and decompression method for high definition image and electronic device using the same |
摘要 |
A lossless image compression method for a high definition image is provided. The image compression method generates a minimum value of values produced by subtracting a current virtual pixel value from an average of neighbor pixels designated by a plurality of directions, as the prediction value of a current pixel. Thus, the image compression more efficient than the current JPEG-LS can be achieved. |
