IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/133100
Kind Code:
A1
Abstract:
Provided is an image processing apparatus having: an image acquisition unit that acquires data of a sample image obtained by imaging a sample; a sample information acquisition unit that acquires sample information to specify a plurality of target colors to be identified in the sample image; a reference white determination unit that determines a reference white based on the sample information; and a color change unit that performs processing of changing a reference white of the sample image to the reference white determined by the reference white determination unit, on the data of the sample image, so as to generate data on a post color change sample image. A reference white which is used for the color change of the sample image is determined, so that an absolute value of the difference of the hue of the plurality of target colors in a predetermined color space for observation becomes greater in the post color change sample image than in the sample image before the color change.
