Abstract:
1. An image processing apparatus, comprising: a reader module for inputting original image data including a pixel color value for each pixel represented by a first predetermined number of n bits in an original image, said reader module approximating the pixel color value into a second predetermined number of m bits while performing error diffusion so as to generate approximated color image data, the m bits being smaller than the n bits; a variable length encoder unit connected to said reader module for variably compressing the approximated color image data to generate further approximated color image data before transmitting the further approximated color image data; a variable length decoder unit connected to said variable length encoder for variably decompressing the further approximated color image data back to the approximated color image data so that each pixel is represented by the m bits; and an image processing/reproduction module connected to said variable length decoder for processing the approximated color image data for performing a combination of image processing, intensity correction and color correction so as to generate processed approximated color image data, said image processing/reproduction module outputting a reproduced image based upon said processed approximated color image data.
