Abstract
Official abstract text for this publication.
With a pixel included in image data as a reference pixel, a pixel that shares the same pixel value as the reference pixel or a pixel similar to the reference pixel is judged as a shared pixel, and for the pixel judged as the shared pixel, color of the reference pixel is regarded as a color judgment result of the shared pixel, thus making it possible to reduce color calculation processing for the shared pixel. This makes it possible to provide a color judging apparatus operating at higher speed and the like. Thereby, it is possible to provide the color judging apparatus operable at high speed and the like by reducing the number of times of the color calculation processing executed for an input image.
First claim
Opening claim text (preview).
The invention claimed is: 1. A color judging apparatus comprising: a color judging portion that calculates a color judgment result of a pixel included in image data by using a pixel value of the pixel for judgment, and a shared pixel judging portion that judges a certain pixel as a reference pixel, and another pixel sharing at least one or more pixel values with the reference pixel as a shared pixel, among pixels included in the image data, wherein the color judging portion, w…
