ABSTRACT:
In order to achieve to adjust saturation of an image without leading to a deterioration in image quality, there is provided an image processing device and method in which a conversion data has a conversion characteristic which suppresses a change in saturation in a visible image for pixels belonging to a predetermined color region, and in order to achieve that changes in image quality which accompany conversion of gradation of an image data can be accurately corrected, there is provided an image processing device and method in which one of reconverting the image data which is converted or controlling a conversion characteristic is performed, such that changes in a ratio of a difference, of each of color components, with respect to gray of each pixel of the image data, which changes accompany conversion of the gradation of the image data, are corrected.
