Abstract:
1. An image processing device, comprising: an obtaining unit that obtains a depth value for each pixel of an input image; a separating unit that separates a gradient of pixel value for each pixel of the input image into a first gradient and a second gradient and that generates a first component image and a second component image, the first gradient including a gradient of a pixel having the gradient whose magnitude is equal to or smaller than a threshold, the second gradient including the gradient of a pixel having a gradient whose magnitude is larger than the threshold, the first component image having the first gradient as a gradient of pixel value for a pixel corresponding to the first gradient, the second component image having the second gradient as a gradient of pixel value for a pixel corresponding to the second gradient a processing unit that enhances each pixel the first component image in accordance with the depth value to generate a processed component image; and a combining unit that combines the processed component image and the second component image to generate a combined component image, wherein, the processing unit increases an enhancement degree of the first component image as a difference between a preset reference value and the depth value decreases.
