Abstract
Abstract An image processing apparatus comprises: an input device for supplying color image information; a discrimination unit to discriminate whether the color image information includes a predetermined image or not in accordance with a color distribution of the color image information supplied by the input device; and a processing circuit to process the color image information in accordance with the result of the discrimination of the discriminating means. The color image information is constructed by a plurality of color component signals. The color distribution is a distribution of the color image information in a color space.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
168 words
An image processing apparatus, comprising: a) input means for inputting color image information of pixels representing an original image; b) memory means for storing reference color information which represents a plurality of colors included in a predetermined color image, the predetermined color image including a predetermined color figure; c) judging means for judging whether a color represented by the color image information input by said input means is one of the plurality of colors represented by said reference color information; d) counting means for counting the number of different colors which are included in both the color image information input by said input means and the reference color information stored in said memory means; e) discriminating means for discriminating whether the input image represented by the color image information includes the predetermined color image including the predetermined color figure or not in accordance with the number of different colors counted by said counting means; and f) output means for outputting a discrimination result obtained by said discriminating means.
Claim 2
Dependent Claim
168 words
An image processing apparatus, comprising: a) input means for inputting color image information of pixels representing an original image; b) memory means for storing reference color information which represents a plurality of colors included in a predetermined color image, the predetermined color image including a predetermined color figure; c) judging means for judging whether a color represented by the color image information input by said input means is one of the plurality of colors represented by said reference color information; d) counting means for counting the number of different colors which are included in both the color image information input by said input means and the reference color information stored in said memory means; e) discriminating means for discriminating whether the input image represented by the color image information includes the predetermined color image including the predetermined color figure or not in accordance with the number of different colors counted by said counting means; and f) output means for outputting a discrimination result obtained by said discriminating means.
