Patent number: 8704910Abstract: An image classification apparatus and method for Automatic White Balance (AWB) are provided. An input image is divided into blocks including pluralities of pixels. A hue value and a chroma value are calculated for each of the blocks. A color-changed block is detected by calculating, for each one of the blocks, differences between the hue and chroma values calculated for all blocks adjacent to the one of the blocks and the hue and chroma values calculated for the one of the blocks. A hue variance and a chroma variance are calculated for the entire input image if a number of the detected color-changed blocks is greater than or equal to a first threshold. The input image is determined as a non-monochromatic image, if the hue variance is greater than or equal to a second threshold or the chroma variance is greater than or equal to a third threshold.Type: GrantFiled: February 11, 2010Date of Patent: April 22, 2014Assignees: Samsung Electronics Co., Ltd, Inha-Industry Partnership InstituteInventors: Ji-Hye Kim, Sung-Dae Cho, Min-Kyu Park, Hee-Chan Park, Jin-Ho Kim, Yun-Je Oh, Kyoung-Tae Kim, Choon-Woo Kim, Seul-Ki Jang

Patent number: 8199363Abstract: An image processing method and an image processing apparatus converts a binary image into a grayscale image by increasing the size and information quantity of the binary image. The image processing method includes generating a plurality of lookup tables having multiple gray level values assigned to a predetermined pattern of the binary image such that the gray level is retrieved from the plurality of lookup tables depending on the context of the block being processed. The binary image may be converted into the grayscale image by applying the gray value of one of the plurality of lookup tables that corresponds to the context, such as the frequency components of the binary image. With this configuration, since the size and information quantity of an image can be reduced for transmission, it is possible to prevent deterioration of image quality when the image is restored, while also printing at a higher speed.Type: GrantFiled: July 24, 2007Date of Patent: June 12, 2012Assignee: SAMSUNG Electronics Co., Ltd.Inventors: Woo-jun Chung, Sang-youn Shin, Choon-woo Kim, Byong-tae Ryu, Jong-ok Lee
