发明名称 Image processing apparatus and method for reducing gradation level of image
摘要 An image processing apparatus includes a first generation portion that generates a first low-gradation image by performing a first process on an input image to reduce the number of gradations of the input image, a second generation portion that generates a second low-gradation image by performing a second process on the input image to reduce the number of gradations of the input image, a density detector that detects a density of the input image, a determination portion that determines, based on the density, a ratio at which the first low-gradation image and the second low-gradation image are blended together, and a mixing portion that blends the first low-gradation image and the second low-gradation image in accordance with the ratio.
