Abstract
Abstract An image forming apparatus and method is provided with the following: a rewritable RAM which outputs as an output image data a 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 it is written; and a RAM. The ROM also stores a 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
An image forming apparatus in which an input image data is printed out after processing by use of an image processing data stored in a memory, wherein a parameter data representative of a characteristic of the image processing data is also stored in the memory, and the input image data is processed with reference to the parameter data.
Claim 2
Dependent Claim
58 words
An image forming apparatus in which an input image data is printed out after processing by use of an image processing data stored in a memory, wherein a parameter data representative of a characteristic of the image processing data is also stored in the memory, and the input image data is processed with reference to the parameter data.
Claim 3
Dependent Claim
80 words
An image forming apparatus according to claim 1, further 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 RAM 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.
Claim 4
Dependent Claim
117 words
An image forming apparatus comprising: a first memory which outputs as an output image data a data at an address corresponding to an input image data, said first memory being rewritable; a second memory in which a data to be written in the first memory is stored; and data processing means capable of processing and changing the data to be written in the first memory before it is written in the first memory, wherein a parameter data representative of a characteristic of the data stored in the second memory is also stored in the second memory, and wherein said data processing means processes the data to be written in the memory with reference to the parameter data.
Claim 5
Dependent Claim
117 words
An image forming apparatus comprising: a first memory which outputs as an output image data a data at an address corresponding to an input image data, said first memory being rewritable; a second memory in which a data to be written in the first memory is stored; and data processing means capable of processing and changing the data to be written in the first memory before it is written in the first memory, wherein a parameter data representative of a characteristic of the data stored in the second memory is also stored in the second memory, and wherein said data processing means processes the data to be written in the memory with reference to the parameter data.
Claim 6
Dependent Claim
31 words
An image forming apparatus according to one of the claims 1 to 3, wherein said parameter data is representative of a way of increase of data in a multi-value dither matrix.
Claim 7
Dependent Claim
51 words
An image forming method in which input image data are printed out after processing by use of a stored image processing data, wherein a parameter data representative of a characteristic of the image processing data is also stored and the input image data are processed with reference to the parameter data.
Claim 8
Dependent Claim
51 words
An image forming method in which input image data are printed out after processing by use of a stored image processing data, wherein a parameter data representative of a characteristic of the image processing data is also stored and the input image data are processed with reference to the parameter data.
Claim 9
Dependent Claim
59 words
An image forming method according to claim 1, further comprising: a half tone processing including the step of storing therein a threshold value for the input image data; performing a fine adjustment processing of the threshold value of the RAM based on the parameter data; and controlling the fine adjustment processing and setting and storing a processed threshold value.
Claim 10
Dependent Claim
28 words
An image forming apparatus according to claims 5 or 6, wherein said parameter data is representative of a way of increase of data in a multi-value dither matrix.
