Abstract
An image processing apparatus and method using a depth image are provided. The image processing apparatus may include a region determination unit to determine a foreground region and a background region in a color image using a depth image, and a color compensation unit to compensate a color with respect to the foreground region and the background region.
Claims19
An image processing apparatus comprising:
- a region determination unit to determine a foreground region and a background region in a color image using a depth image;
- and
- a color compensation unit to compensate a color with respect to the foreground region and the background region,
- wherein, in a compensating for a distorted color of the background region, the color compensation unit does not apply histogram equalization to the foreground region but applies histogram equalization to the background region, extracts white balance from the foreground region to which histogram equalization is not applied, and applies histogram equalization using the extracted white balance to compensate for the distorted color of the background region.
