Abstract
Abstract An image processing apparatus in which a color identifier identifies the color of an input image based on an input color-image signal. A luminance detector detects luminance information in the input color-image signal. An image generator generates a predetermined pattern which is indicative of the color identified by the color identifier. A measurement device measures the luminance distribution of the detected luminance signal which is outside an area in which color is identified by the color identifier. The output density of the input color-image signal is set in accordance with the measured luminance distribution, and an output monochromatic image is produced in which colors of the input image are identified by the predetermined patterns.

Claim 69
Dependent Claim
78 words
An image processing method comprising the steps of: identifying a color of an input color image based on an input color image signal; applying predetermined image processing to the input color image signal; measuring a distribution of signal level of the color image signal except for an area of the input color image in which color is identified; and determining a signal level of the input color image signal to be output in conformity with the distribution measured.
Claim 70
Dependent Claim
78 words
An image processing method comprising the steps of: identifying a color of an input color image based on an input color image signal; applying predetermined image processing to the input color image signal; measuring a distribution of signal level of the color image signal except for an area of the input color image in which color is identified; and determining a signal level of the input color image signal to be output in conformity with the distribution measured.
Claim 71
Dependent Claim
173 words
An image processing apparatus for inputting a color image signal representing an image containing color, and outputting a pattern which corresponds to a color of the color image signal, comprising: correcting means having a first correction coefficient for a case where luminance information is not output with regard to the color image signal, and a second correction coefficient for a case where luminance information is output with regard to the color image signal, for applying a shading correction to the color image signal using the first and second correction coefficients; measuring means for measuring a luminance distribution of the color image signal corrected by said correcting means; color identifying means for identifying a color of the color image signal based upon the color image signal corrected by said correcting means; luminance information generating means for generating predetermined luminance information based upon the color identified by said color identifying means; and setting means for setting an output density of the color image signal in conformity with the luminance distribution measured by said measuring means.
