摘要
The image processing apparatus according to the present invention includes: a segmentation process section for performing a segmentation process with respect to image data corresponding to an image to be processed; first and second input tone correction sections each of which performs a density correction process with respect to the image data by referring to a conversion curve which indicates a relation between density before correction and density after correction; and a processing mode control section for switching between (i) a first processing mode in which the segmentation process is performed with respect to the image data having been subjected to the density correction process and (ii) a second processing mode in which the segmentation process is performed with respect to image data having not been subjected to the density correction process. Therefore, the image processing apparatus can perform the segmentation process with high accuracy.
