Abstract:
1. A non-transitory computer readable storage medium storing an interpolation method determination program for making a computer execute a process for determining an interpolation method for interpolating respective pixel values of plural pixels which do not exist in an input image and which are positioned on a straight line, the process comprising: a target pixel selection by selecting, sequentially in accordance with a designated selection sequence direction, one pixel from among the plural pixels as a target pixel for which the interpolation method needs to be determined; calculating a local correlation value for each one of designated plural correlation calculation directions using a cumulative correlation value calculation obtaining a plurality of cumulative correlation values, a direction selection by selecting one of the plural correlation calculation directions according to the cumulative correlation values corresponding to the respective plural correlation calculation directions; and an interpolation-use pixel determination by determining plural pixels used for interpolating the target pixel according to at least either
