Title:
IMAGE PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2013121154
Kind Code:
A
Abstract:
To solve a problem that, in the case that a code amount exceeds an allowable range in encoding of attribute information related to each pixel, because a part of information is converted and encoded independently of characteristics of each attribute flag to improve a compression rate, reversibility is lost even in data that can maintain reversibility, and an effect of image processing based on the attribute information cannot be obtained.
By arranging for each attribute flag, encoding, and changing an encoding method of each attribute flag on the basis of a code amount of each attribute flag group, encoding with the minimum loss in reversibility can be executed.
