Abstract
Abstract A color image processing system is provided which receives binary image data from an external device, which generates the binary image data, so as to form color images. This system has a first mode in which a receiving side receives the same binary image signal color plane by color plane so that a color process is performed. It also has a second mode in which a printer receives binary image data in a plane sequence, which data indicates color planes corresponding to the types of coloring materials used for a printing operation of the printer, and then, the printer performs binary printing in accordance with the binary image data. An indicating device for indicating the first or second mode selects the first or second mode with respect to the binary image data from the external unit.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
76 words
An image processing system comprising: first means for receiving pattern data from an external unit through a predetermined line and for performing a color process so as to output the pattern data, said color process being performed in accordance with information on coloration fed before; and second means for receiving color data from said external unit through said predetermined line so as to output the color data which contains a plurality of color components sequentially transmitted.
Claim 2
Dependent Claim
22 words
An image processing system according to claim 1 further comprising selecting means for selecting either said first means or said second means.
Claim 3
Dependent Claim
27 words
An image processing system according to claim 2, wherein said selecting means selects either said first means or said second means in accordance with a manual operation.
Claim 4
Dependent Claim
22 words
An image processing system according to claim 1, wherein said second means transmits in a plane sequence said plurality of color components.
Claim 5
Dependent Claim
18 words
An image processing system according to claim 1, wherein said first means repeatedly receives the same pattern data.
Claim 6
Dependent Claim
24 words
An image processing system according to claim 1, wherein said pattern data and said information on coloration are transmitted in a time series manner.
Claim 7
Dependent Claim
31 words
An image processing system according to claim 1 further comprising image forming means for forming an image in accordance with an output from either said first means or said second means.
Claim 8
Dependent Claim
20 words
An image processing system according to claim 7, wherein said image forming means is a printer of an electrophotographic process.
Claim 9
Dependent Claim
108 words
An image processing system comprising: common inputting means; first means for performing a color process with respect to image data input from said inputting means so as to output the image data, said color process being performed in accordance with information on coloration fed before; second means for performing a color process with respect to the image data input from said inputting means, said color process being performed irrespectively of said information on coloration; control means for operating either said first means or said second means; and image forming means for forming an image in accordance with an output from either said first means or said second means.

Dependent Claim
22 words
An image processing system according to claim 9, wherein said second means transmits a plurality of color components in a plane sequence.
Claim 12
Dependent Claim
20 words
An image processing system according to claim 9, wherein said image forming means is a printer of an electrophotographic process.
Claim 13
Dependent Claim
60 words
An image processing system comprising: setting means for setting conditions under which density is corrected; first processing means for processing first image data in accordance with first density data set by said setting means; and second processing means for processing second image data, different from said first image data, in accordance with second density data set by said setting means.
Claim 14
Dependent Claim
17 words
An image processing system according to claim 13, wherein said first image data is multi-value image data.
Claim 15
Dependent Claim
17 words
An image processing system according to claim 13, wherein said second image data is binary image data.
Claim 16
Dependent Claim
35 words
An image processing system according to claim 13 further comprising synthesizing means for synthesizing the first image data processed by said first processing means and the second image data processed by said second processing means.
Claim 17
Dependent Claim
28 words
An image processing system according to claim 13, wherein said setting means sets with the aid of a manual operation the conditions under which the density is corrected.
Claim 18
Dependent Claim
21 words
An image processing system according to claim 13, wherein said second image data is color image data in a plane sequence.
Claim 19
Dependent Claim
39 words
An image processing system comprising means for receiving print shape data and colour data, characterised by means for generating print data in response to said print shape data and either said received colour data or locally defined colour data.
