A method and apparatus for applying a tile size adaptively based on a size of a coding unit. An image processing apparatus may detect a size of a largest coding unit (LCU) used in encoding of a video from a header of a bitstream, may determine a tile size adaptively based on the detected size of the LCU, and may decode the bitstream in units of the LCU based on the determined tile size.

Image processing apparatus and method

An image data encoding apparatus and method and an image data decoding apparatus and method are provided. The image data encoding apparatus may perform at least one image prediction with respect to image data, and select a prediction mode for encoding. The image data encoding apparatus may simultaneously perform both intra prediction and color prediction, and thereby may efficiently perform encoding.

Apparatus and method of encoding and decoding image data using color correlation

An apparatus and a method for dividing image data into partition slices and encoding and decoding the image data based on a correlation between macroblocks are provided. The macroblocks may be decoded in parallel and thus, it is possible to improve an overall image quality and processing speed.

Apparatus for dividing image data and encoding and decoding image data in parallel, and operating method of the same

Provided is an apparatus and method of dynamically distributing load occurring in multiple cores that may determine a corresponding core to perform functions constituting an application program, thereby enhancing the entire processing rate.

Apparatus and method of dynamically distributing load in multiple cores

An image encoding system and method for performing random access may be provided. The image encoding system may perform intra prediction based on a processing unit, and code a pixel using a result of the intra prediction. Also, the image encoding system may generate a bitstream with respect to an input image using a Fixed Length Code (FLC). Coding may be performed based on the processing unit, and thus random access may be performed based on the processing unit.

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.

Apparatus and method for adjusting auto white balance using effective area

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.

System and method for automatic exposure

A pixel data compression/decompression system, medium, and method, including determining the similarity between a first pixel data and a second pixel data adjacent to the first pixel data, selecting one of a first compression mode, where a difference between a compression ratio of the first pixel data and a compression ratio of the second pixel data is high, and a second compression mode, where a difference between a compression ratio of the first pixel data and a compression ratio of the second pixel data is low, based on the similarity, and compressing the first pixel data and the second pixel data based on the selected compression mode.
