摘要： An image display apparatus and a color distortion compensation method are provided. The image display apparatus includes a detecting part which detects whether there is a color distortion in a block, using decoding information acquired from an incoming image and a pixel value of the incoming image, and a compensation part which compensates for the color distortion of the block when it is determined that the color distortion exists. Accordingly, it is possible to detect a color distortion in the block using the decoding information and pixel value acquired from the incoming image, and compensate for the color distortion of the block by performing pixel value adjustment and low pass filtering (LPF) when it is determined that the color distortion exists.

The image quantization method includes determining a possibility of color distortion in the block using discrete cosine transform (DCT) coefficients and pixel values of the block of predetermined size of an image and performing initial quantization on the block using a predetermined color distortion quantization matrix to remove color distortion if the block has a high possibility of color distortion.

摘要： Provided is an apparatus and method for detecting an image enhanced from a low resolution image to a high resolution image. An apparatus detects an image converted from a first resolution to a higher second resolution. A frequency converter converts a received second resolution image signal to a frequency domain. An image determiner calculates energy per frequency from the received second resolution image signal. If an amount of energy in over a pre-set frequency is less than a threshold, the received second resolution image signal corresponds to a second resolution image converted from a first resolution image, and if the amount of energy in over the pre-set frequency is greater than the threshold, determining that the received second resolution image signal corresponds to a real second resolution image.
