IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND COMPUTER READABLE MEDIUM

The invention provides an image processing apparatus, an image processing method and a computer readable medium. The image processing apparatus includes: an input device to which images before color conversion and images after color conversion are input; and a processor. The processor is configured to execute a program to perform color conversion on a sample image using color conversion characteristics prepared by inputting sets of the images before color conversion and the images after color conversion to the input device, specify a portion at which a tone jump is caused from the sample image after color conversion, and acquire a set of an image before color conversion and an image after color conversion corresponding to the portion at which the tone jump is caused from the sets, to prepare the color conversion characteristics again using the acquired set of images. 提供图像处理装置、图像处理方法及计算机可读介质。一种图像处理装置，其具有：输入装置，其输入颜色变换前的图像和颜色变换后的图像；以及处理器，所述处理器通过执行程序，从而根据将所述颜色变换前的图像和所述颜色变换后的图像的组输入到所述输入装置而生成的颜色变换特性，对样本图像进行颜色变换，确定颜
