Bit plane compression device and bit plane compression / restoration method

摘要

A bit plane compression apparatus and a bit plane compression / decompression method are disclosed. A bit plane compression apparatus according to the present invention includes a frame memory for separating bit planes according to a first control signal for counting the position of each pixel and outputting the bit plane data as bit plane data, n data reversal means, n bit reversal means, n bit reversal means, respectively, for outputting the compressed bit plane data, a second data compression means for outputting the compressed bit plane data, A multiplexer for serially transmitting the compressed bit plane data in response to the selection signal, a multiplexer for multiplexing the inverted signal generated as n bit inversion signals corresponding to the number of bits of the n bit inversion signal, A first control signal corresponding to the generating means and the system clock signal and the horizontal reference signal, And a memory control means for generating two control signals and generating a selection signal. Since the digital data for each pixel is divided into bit planes and processed, it is possible to increase the data compression rate and increase the transmission efficiency, It is possible to perform the image processing at a time, and since it can be restored as software without a separate device, the image processing camera can be manufactured at low cost.
