Color image processing apparatus

Claim 2

In a color image processing apparatus obtaining a plurality of color information, the improvement in that said apparatus comprises a color extraction means for deciding a color, means for eliminating color ghost from the obtained color information by said color extraction means, and a density processing means for performing density correction according to color ghost information resulted from said means for eliminating color ghost.

Claim 3

The apparatus of claim 1, wherein said color ghost eliminating means performes the color ghost elimination by plural times.

Claim 4

The apparatus of claim 1, wherein the color information comprises a color code information and a density information.

Claim 5

The apparatus of claim 3, wherein the color ghost elimination is applied onto the color code information.

Claim 6

The apparatus of claim 3, wherein the density correction is applied onto the density information.

Claim 7

The apparatus of claim 3, wherein the density information is binary coded and the color code information to be stored in memory is controlled by the binary data.

Claim 8

The apparatus of claim 3, wherein the density information is coded into three state after binary coding and the color code information to be stored in memory is controlled by the three state coded data.

Claim 9

A color image processing apparatus comprising image reading means for photoelectrically obtaining a plurality of color signals per one pixel of original color image, color extraction means for storing a plurality of pairs of data comprising color code data and density data, said color extraction means outputting a pair of data comprising color code data and density data in response to the plurality of color signals obtained by said image reading means, color ghost eliminating means for storing a pluraity of color pattern representing serial color code data, said color ghost eliminating means comparing color pattern of the color code data outputted from said color separating means with the stored color pattern and correcting the color code data in accordance with the comparison result, and said color ghost eliminating means further performing to correct the density data in accordnace with the corrected color code data.

Claim 10

A color image processing apparatus comprising image reading means for photoelectrically obtaining a plurality of color signals per one pixel of original color image, color extraction means for storing a plurality of pairs of data comprising color code data and density data, said color extraction means outputting a pair of data comprising color code data and density data in response to the plurality of color signals obtained by said image reading means, color ghost eliminating means for storing a pluraity of color pattern representing serial color code data, said color ghost eliminating means comparing color pattern of the color code data outputted from said color separating means with the stored color pattern and correcting the color code data in accordance with the comparison result, and said color ghost eliminating means further performing to correct the density data in accordnace with the corrected color code data.
