Abstract: An image forming apparatus to save toner, which can increase the sharpness of printed data (for example, images or characters) on a printing medium while achieving toner saving, and a method to control the same. The image forming apparatus includes a determinator, a storage unit, and a halftoning processor. The determinator receives a command signal to print and then determines whether or not the received command signal is a command signal for a toner saving mode. The storage unit stores a halftone table in which an LPI higher than a normal LPI is set. If the received command signal is a command signal for the toner saving mode, the halftoning processor generates and outputs halftoning result by comparing gray level values corresponding to pixels of received input image data with grayscale values of the stored halftone table.

Abstract: A system and method of rapidly compressing and decompressing a binary image. The method of rapidly compressing the binary image includes initializing a 0 count value obtained by counting 0 blocks and also initializing a 0 output control value that is information on the number of continuous 0 blocks; estimating pixel values of a current block using binary values of a previous line continuously input immediately prior to the current line to be coded and also using screen mask values of the previous line; estimating binary values of the current block using the estimated pixel values and the screen mask values corresponding to the current block; comparing the estimated binary values with corresponding ones of the actual binary values of the current block to calculate errors and to thus generate an error pattern; and coding the current line block by block based on the 0 count value, the 0 output control value, and the generated error pattern. A reverse order of operation of the method may be used during the rapid decompression of a coded input image. Therefore, the image data may be rapidly compressed and decompressed on a block-by-block basis using the pixel values of the previous line.
