Abstract: An image tuning system and method using a stored image signal, in which the image tuning system includes an image processing device and an external device. The image processing device outputs a third image signal by processing a first or second image signal according to a tuning parameter. The external device calculates the tuning parameter based on the third image signal. The image processing device receives the second image from the external device in a tuning mode and processes the second image. The image tuning system and the image tuning method using the stored raw image signal can prevent wasting time and extra efforts are not required for setting the tuning parameter adaptive to various weather conditions by repeatedly setting the tuning parameter with respect to a picture image.

Abstract: A method and an apparatus for calculating source image coordinates. In an embodiment, a variation rate of the source image coordinate with respect to a converted image coordinate is calculated by a recursive computation, and variation rates are accumulated to obtain the source image coordinate. Because the converted image coordinate sequentially increases one-by-one, the variation rate may be obtained by using adding operations of previously obtained source image coordinate, rather than multiplying operations with the all of the converted image coordinates. Therefore, the source image coordinates may simply and effectively be calculated.

Abstract: The present invention is an interpolation device and method. According to the present invention, a plurality of pixels close to a pixel to be interpolated are sequentially set to a central pixel. When a pixel difference closest to a threshold value among pixel differences between the central pixel and a plurality of pixels around the central pixel belongs to a quasi-edge decision range, an edge interpolation and a bilinear interpolation are mixed to interpolate the pixel to be interpolated. As a result, it is possible to prevent reduction in image quality due to an edge verdict caused by unstable input image signal and perform a stable interpolation operation.
