摘要

In each of upscale circuits (12a to 12d) to which each of divided image data is inputted, a difference circuit (31) for calculating the gradation value of a pixel of interest so that edges in an image are extracted by using the differentiation or difference of gradation values in the vicinity of the pixel of interest, an averaging circuit (34) for calculating the gradation value of the pixel of interest so that the gradation values in the vicinity of the pixel of interest are averaged, and a correlation computing circuit (35) for calculating a correlation value indicating the correlation between the difference image data in which difference computing processing is applied to the divided image data and the averaged image data in which the difference computing processing and the averaging processing are applied to the divided image data are provided. Interpolation processing is applied to the divided image data by an interpolation method in accordance with the calculated correlation value. This makes it possible to generate a high resolution image without increasing circuit size and processing time in an image processing device for dividing input image data into a plurality of areas of image data and converting the resolution of each of the divided image data into high resolution.
