    • Color image data composed of pixels arranged in a matrix wherein colors are expressed in bit rows is created from an acquired document file, and same-resolution binary image data and low-resolution binary image data composed of binary pixels arranged in a matrix are created based on the color image data. A first combining process is performed in which a lower bit value of a predetermined color of the pixels of the color image data is replaced with the value of the corresponding ones of the pixels of the same pixels, and a second combining process is performed in which a lower bit value of a color other than the bit replaced in the first combining process in the pixels of the first combined image data is replaced with the value of the corresponding ones of the pixels of the low-resolution binary image data.

    • A data compressing method which can efficiently compress image data containing color data is provided. A compressed data expanding method which can expand the compressed data at high speed is provided. Image data containing color data are compressed into image data including: address fields code A, code B, code C which hold addresses of color RAMs storing color information corresponding to the color data; classification fields which, when the color RAMs are classified into prescribed categories A, B, C, hold classification information of the categories including the color data; and run length fields RL which hold numbers of successive repetitions of color data. To expand the compressed image data, the classification fields are decoded to determine the categories in which the color data are included. Based on the determined categories, the first processing for decoding the address fields to generate addresses, and the second processing for supplying the generated addresses by the numbers of successively repeated color data in the run length fields to access the color RAMs are performed.

    • The present invention relates to a bit-map compressing method and a bit-map compressing device. The bit-map data compressing method includes a main scanning step for scanning bit-map data in a main scanning direction; a first region separating step for separating a region including black pixels and a region including no black pixels in line unit; a secondary scanning step for scanning in a secondary direction perpendicular to the main scanning direction; a second region separating step for separating a region including black pixels and a region including no black pixels, in column unit; and an encoding step for encoding as an element each region obtained in the first region separating step and the second region separating step. Bit-map can be transferred by effectively performing data compression on simple algorithm, without using special hardware.
