ABSTRACT:
Bitmap digital image data having one or more color channels is divided into image sizes corresponding to an optimum processing unit set according to computer's processing capability and requested image quality. Each unit image data is further divided according to the respective color channels in order to generate multiple minimum processing units of image data. After respective horizontal rows of the minimum processing unit of image data are 2D-vectored based on the horizontal positions x and luminance levels y of the respective pixels therein, quantized according to changes in luminance levels using line elements connecting the starting points and end points of the respective rows as reference vectors, and applied with shaping processing, the respective vertical rows are 2D-vectored based on the horizontal positions x and luminance levels y in the same manner and quantized according to the changes in luminance levels using line elements connecting the starting point and the end point of the respective rows as reference vectors in order to convert the image data into compressed image data with a matrix structure based on the significance of the luminance information contained in the respective pixels. After said minimum units of compressed image data are further compressed mathematically, the color channels are integrated in order to generate optimum processing units of compressed image data; and they are further integrated in order to generate compressed image data for the entire original image.
