Abstract
An image forming apparatus is provided with the following: rewritable RAM which outputs as output image data, data at an address corresponding to an input image data; a ROM in which a data to be written in the RAM is stored; a data processing CPU capable of processing and changing the data to be written in the RAM before the data are written; and a RAM. The ROM also stores parameter data representative of the characteristic of the data stored therein. The CPU and the RAM process the data to be written in the RAM with reference to the parameter data.
Claims5
An image forming apparatus in which input image data are printed out after being processed by use of image processing data stored in a memory, wherein parameter data representative of a characteristic of the image processing data are also stored in the memory, and the input image data are processed with reference to the parameter data, said apparatus comprising:
- a half tone processor including a random access memory for storing therein a threshold value for the input image data;
- a work random access memory for performing a fine adjustment processing of the threshold value of the random access memory based on the parameter data;
- and
- controlling means for controlling the fine adjustment processing by the work random access memory and for setting a processed threshold value in the random access memory.
