PURPOSE:To easily convert an original image to a picture element string for a raster signal, by performing the development of continuous black pattern data, that of novel black pattern data, that of continuous white pattern data, and that of novel white pattern data in order. CONSTITUTION:First of all, raster element data is generated at a generating part 101 corresponding to the continuous black pattern data of a storage part 102, and a value representing the crossing of a raster and a pattern is set at the corresponding part of a picture element storage part 105 by a developing part 103 based on said generated data. And when the pattern appears at the next raster position, the pattern data at that time is stored in the storage part 102. After a round of the development of the pattern data for the data of the storage part 102 is completed by those operations, the development of the novel black pattern data of a storage part 302 is performed similarly. After that, after completing a round of the development of the continuous white pattern data of a storage part 108, the development of the novel white pattern data of the storage part 302 is performed. |
