Abstract
Abstract A color graphic image processing method which first reads color graphic image to be processed, and then encodes read-out signals into 4 through 6 units of encoded words per each color, and then stores the encoded words after completing compression of data. The system then transmits the stored data and converts them into image signals suited for output device before eventually allowing the output device to output these image signals.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
A color graphic image processing method executing sequential steps of; reading color graphic image to be processed by means of a color image input device; encoding read-out image signal into 4 through 6 units of encoded words per each color by means of an input device; compressing said encoded data; storing said compressed encoded data in a storage device; transmitting said stored data; converting said transmitted data into the one suited for an output device; and supplying complete image signal to an output device.
Claim 2
Dependent Claim
84 words
A color graphic image processing method executing sequential steps of; reading color graphic image to be processed by means of a color image input device; encoding read-out image signal into 4 through 6 units of encoded words per each color by means of an input device; compressing said encoded data; storing said compressed encoded data in a storage device; transmitting said stored data; converting said transmitted data into the one suited for an output device; and supplying complete image signal to an output device.
Claim 3
Dependent Claim
32 words
The color graphic image processing method in accordance with claim 1, in which encoding of read-out image signal is done by selected encoding process capable of absorbing characteristics of individual input devices.
Claim 4
Dependent Claim
32 words
The color graphic image processing method in accordance with claim 1, in which decoding of encoded image signal is done by selected decoding process capable of absorbing characteristics of individual output devices.
Claim 5
Dependent Claim
42 words
The color graphic image processing method in accordance with claim 1, further executing sequential steps of; following encoding of read-out image signals into 4 through 6 units of encoded words, executing run-length encoding operation; and further compressing data for improving compression rate.
Claim 6
Dependent Claim
32 words
The color graphic image processing method in accordance with claim 1, further comprising steps of detecting picture element causing encoded word to vary itself as edge picture element for sharpening image edge.
Claim 7
Dependent Claim
68 words
The color graphic image processing method in accordance with claim 1, further executing sequential steps of; following reading of color graph image and encoding it into 4 through 6 units of encoded words; compressing data and storing compressed data in a storage device; transmitting stored data for applying necessary processes; and supplying said processed data to an output device before eventually allowing complete image signals to be output.
