摘要： An interpolation computation unit (3B) treats, as positions of interest, positions where pixels within a high-resolution image (D30) occupy when the high-resolution image (D30) is superimposed on a low-resolution image (D01), and for each position of interest, obtains a pixel value for a pixel assumed to exist at the position of interest by performing an interpolation computation using pixel values of a plurality of pixels within the low-resolution image (D01). An interpolation coefficient calculation unit (3A) obtains interpolation coefficients (D3A) having values that increase with increasing strength of correlation of the pixels in the plurality of pixels in the low-resolution image with the pixel of interest, and outputs the interpolation coefficients to the interpolation computation unit (3B). Angles of edges and shapes of edges are not classified into any predetermined patterns; therefore, it is possible to perform suitable interpolation computations regardless of edge shape.

摘要： To obtain a high resolution image from two or more low resolution images, positional offsets among the low resolution images are determined and the low resolution images are mapped onto a common plane according to the positional offsets. Pixel values in the high resolution image are calculated by weighted interpolation from the pixel values of the low resolution images, using interpolation coefficients that increases with increasing correlation with the pixel of interest. Correlation is determined by taking horizontal and vertical first and second derivatives of the pixel values in one low resolution image to find a direction of strong correlation. Appropriate interpolation is thereby obtained even near edges and other abrupt changes in the image.

摘要： An image processing apparatus has an image analyzer including a feature detector, a feature combiner, and a resolution discrimination signal generator. For each pixel in a prescribed area of an input image, the feature detector outputs a representative difference value obtained from the pixel values of pixels positioned, with reference to that pixel, at prescribed intervals. The feature combiner outputs a combined feature value obtained from the representative difference values obtained for each pixel in the described area. The resolution discrimination signal generator outputs a resolution discrimination signal obtained from the combined feature value. The resolution discrimination signal has a monotonic non-decreasing relationship to the combined feature value. The resolution discrimination signal indicates an extent to which the input image includes signal components with frequencies equal to or greater than a particular frequency determined by the prescribed intervals.
