A method of adjusting value includes calculating a value of saturation from an input image signal, and adjusting a value of value of the input image signal according to a calculated saturation value. In the method, the value of value of the input image signal is adjusted by using a value adjustment algorithm for determining a value adjustment rate that decreases the value according to the saturation value.

Provided are frame interpolation apparatus and methods in which motion estimation is performed by separation into a static object and a moving object. The frame interpolation apparatus interpolates multiple frames including an nframe and an (n&#x2212;1)frame located adjacent the nframe in order to generate an interpolation frame. Some embodiments of the apparatus include a static object separation unit, a motion vector (MV) estimation unit, and an interpolation frame generation unit. The static object separation unit may compare a macroblock (MB) of the nframe with an MB of the (n&#x2212;1)frame, which may correspond to the MB of the nframe, in order to separate each MB of the nframe into a static object and a moving object. The MV estimation unit may search in the (n&#x2212;1)frame for an MB that matches with each of MBs of the nframe, which may be determined to be the moving object, to estimate an MV. The interpolation frame generation unit may generate the interpolation frame using the estimated MV, the nframe, and the (n&#x2212;1)frame.

A contrast control apparatus includes a memory for storing input image signals within one frame and an image reducing unit for selecting at least one image signal of the input image signals. An accumulation value calculating unit calculates accumulation values for predetermined sampling gray values with respect to the selected image signal. An image characteristic decision unit determines at least one characteristic of the selected image based on the accumulation values. A contrast control function calculating unit calculates a contrast control function based on the characteristic of the selected image. A contrast controller controls contrast of the image signals stored in the memory according to the contrast control function.

A method of changing a pixel color includes determining whether a chrominance of a pixel is in a preference chrominance area, where the preference chrominance area is defined as a conic section in a two-dimensional chrominance plane and an eccentricity of the conic section is not greater than 1, and changing the chrominance of the pixel to a preference chrominance to generate a preference pixel when the chrominance of the pixel is in the preference chrominance area. Therefore, the method may set a preference chrominance area in a simple manner, and hardware for setting the preference chrominance area may be easily implemented.
