Title:
COLOR DETERMINATION DEVICE, COLOR DETERMINATION METHOD, IMAGE PROCESSING CIRCUIT, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/145728
Kind Code:
A1
Abstract:
Disclosed is a color determination device provided with: a storage unit which stores the pixel value and the color determination result corresponding to said pixel value; a similarity determination unit which determines that a current pixel, the color of which is to be determined and which is included in an image data, is a similar pixel if the pixel value of the current pixel and the pixel value stored in the storage unit are within a predetermined range when the color of the current pixel is being determined; and a color determination unit which sets the color determination result stored in the storage unit as the color determination result of the current pixel if it is determined that the current pixel is a similar pixel by means of the similarity determination unit. As a consequence, the frequency of determining whether or not the pixel of an inputted image is within a predetermined range is reduced, thereby being able to provide a color determination device which can operate at high speed.
