    摘要: Disclosed herein is an apparatus and method for balancing the color of a flashed image using depth estimation. The apparatus includes a depth value measurement unit, a region identification unit, a color impression estimation unit, and a color balancing unit. The depth value measurement unit measures the depth values of the respective regions of an image to be captured using a camera preview image. The region identification unit identifies the regions of the preview image as a region influenced by camera flash or a region not influenced by camera flash using the depth values measured by the depth value measurement unit. The color impression estimation unit estimates the color impression of actual illumination in the region not influenced by camera flash. The color balancing unit corrects the color of the region influenced by camera flash.

    摘要: Disclosed herein is an apparatus for enhancing images in consideration of region characteristics. An inverse gamma correction unit releases gamma correction and linearizes each of Red (R), Green (G), and Blue (B) colors. A threshold calculation unit calculates m-1 thresholds in order to divide the brightness of pixels into m regions, and labels each of the pixels as one of the m brightness regions. A block segmentation unit divides an input image into M×N blocks. A block statistics calculation unit determines one of the m brightness regions to which each of the blocks pertains, and labels the block as the corresponding brightness region. A block-based Look-Up Table (LUT) generation unit generates enhancement LUTs for the respective blocks. An image enhancement unit corrects the image using the LUTs for the respective blocks. A gamma correction unit performs gamma correction.
