摘要： An image interpolating method for interpolating a pixel at an intermediate position between a first original pixel and a second original pixel adjacent to the first original pixel, comprising a first step of calculating an edge component for judging whether or not an interpolated pixel is positioned in the vicinity of an edge position of original image data, a second step of determining a range where pixel data on the interpolated pixel is settable on the basis of the calculated edge component and pixel data on the first and second original pixels, and a third step of selecting a plurality of sets of opposed pixels between which the interpolated pixel is sandwiched diagonally, and determining, for each of the sets, the pixel data on the interpolated pixel in a case where a correlation value represented by the sum of the absolute values of the differences between the pixel data on the interpolated pixel and pixel data on the opposed pixels is the minimum in the range where the pixel data on the interpolated pixel is settable and the minimum correlation value.

摘要： Provided are an apparatus, a method, and a program for processing an image which reduces crosstalk and achieves high image quality. The method includes obtaining a differential signal by subtracting one input image signal of an object to be processed from another input image signal; applying a predetermined correction coefficient to the differential signal; determining, for each pixel, whether the differential signal is a negative value; selectively outputting, for each pixel, the differential signal, to which the predetermined correction coefficient is applied, as a correction signal based on a result of the determining; and correcting, for each pixel, the one input image signal based on the one input image signal and the correction signal that is selectively output if the differential signal is the negative value.

摘要： Disclosed is an interpolation pixel value determining method for dividing a unit region including the contour of an object into reference unit sections for each line along a predetermined direction, to find, using a region interposed between the two reference unit sections as an interpolation unit section, an interpolation pixel value in the interpolation unit section, in which a luminance total and a center of gravity are calculated in each of the two reference unit sections with the interpolation unit section interposed therebetween, the estimated values of a luminance total and a center of gravity in the interpolation unit section are found from the luminance totals and the centers of gravity in the two reference unit sections, and each of interpolation pixel values in the interpolation unit section is determined such that the luminance total and the center of gravity in the interpolation unit section are respectively values close to the estimated values.
