According to one embodiment, an image processing apparatus includes a chroma calculation unit, a lightness calculation unit, a glossiness calculation unit, and a correction unit. The chroma calculation unit is configured to calculate a chroma of each pixel of an image to be processed. The lightness calculation unit is configured to calculate a lightness of each pixel of the image. The glossiness calculation unit is configured to estimate a glossiness of each pixel of the image, based on the chroma and the lightness. The correction unit is configured to correct each pixel of the image so that a correction amount of a pixel is larger when the glossiness of the pixel is higher.
