    摘要: An apparatus and method for auto white balance adjusting using an effective area. The auto white balance adjusting apparatus may extract a grey area from an input image, and select an effective area from the grey area according to color temperature and luminance, thereby performing white balance using the effective area. The auto white balance adjusting apparatus may perform white balance of the input image using image information of the effective area which is a more precise grey area, thereby improving the white balance.

    摘要: Disclosed are an auto exposure system and a method thereof. The auto exposure system may check whether an exposure target value is correct using brightness information of an input image. When the exposure target value is not proper, the auto exposure system may readjust the exposure target value through analyzing the brightness information of the input image. Also, the auto exposure system may correct exposure of the input image based on an exposure correction value according to the adjusted exposure target value, thereby adjusting the exposure of the input image to be proper. Also, exposure information of the input image may be easily obtained from a final exposure target value.

    摘要: An image data encoding/decoding apparatus and method using sampling is provided. The image data encoding apparatus may compress image data, pre-processed for each block, after sampling or without sampling, and select a more efficient compression mode from results of the compressing. The image data decoding apparatus may determine a decompression mode corresponding to the selected compression mode, and up-sample the image data after decompressing the image data based on a decompression mode, or decompress the image data without sampling, to provide high definition regardless of a type of image data.
