20090074328 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus calculates estimated pixel values of respective pixels of a provisional high-resolution image by interpolation on basis of pixel values in a reference frame, segmentalizes interior of the reference frame into an edge region, a texture region or a flat region and other on basis of pixel values of respective pixels, sets the respective pixels in the reference frame as target pixels one by one in sequence, calculates corresponding positions on the provisional high-resolution image, of the respective target pixels in fractional pixel accuracy on basis of information on the segmented regions including the target values, modifies the estimated pixel values so that difference from the pixel values of the target pixels to provisionally estimated pixel values obtained from the estimated pixel values of the provisional high-resolution image for pixels around the corresponding positions of the target pixels, becomes smaller, and obtains modified pixel values. | 03-19-2009 |
20120163720 | IMAGE PROCESSING APPARATUS AND METHOD THEREOF - A specifying unit specifies a pixel value at a pixel position of a reference image to a pixel of a sample enlarged image at a position relative to a pixel position of the reference image as an initial pixel value. A selecting unit selects a target pixel from pixels other than pixels having the pixel values specified therefor including the pixels having the initial pixel values are set in the sample enlarged image. An allocating unit configured to allocate the pixel value of the pixel at a similar region position of the reference image to the pixel value of the target value in the sample enlarged image when a searching unit searches the similar region position similar to a pixel value pattern including a set of already specified pixels in a spatial neighborhood of the target pixel from the reference image is provided. | 06-28-2012 |
