Document Type and Number:
WIPO Patent Application WO/2013/164938
Kind Code:
A1
Abstract:
[Problem] To provide an image processing device for obtaining a high-quality image.
[Solution] The image processing device comprises: a pixel value acquiring means (121) for acquiring the pixel value of a new pixel by using the pixel values of a plurality of original pixels of a first image around a position where the new pixel is disposed, the new pixel being obtained by increasing the resolution of the first image; a representative value acquiring means (122) for acquiring a representative value of the pixel values of a plurality of new pixels disposed in each region where each original pixel is disposed; a correction value acquiring means (123) for acquiring a correction value from the pixel value of each original pixel and the representative value obtained in the region where each original pixel is disposed; and a pixel value correction means (124) for correcting the pixel value of each original pixel by using the correction value. The above correction processing for correcting the original pixels is repeated one time or two or more times, and the pixel values of the original pixels corrected by repetition are used to acquire a second image that is constituted by the new pixels having the pixel values acquired by the pixel value acquiring means (121).
