Abstract:
An apparatus for expanding original image data, in which a plurality of pixels is arranged in a matrix, so as to obtain expanded-image data partitioned into a plurality of blocks, each of which is composed of a plurality of pixels, said apparatus comprising:a magnifying power setting processor that sets a magnifying power regarding at least one of a first direction along a width and a second direction along a length in said original image data; a pixel arranger that arranges each pixel in said original image data at a position corresponding to a center position of each of said plurality of blocks in accordance with said magnifying power; an expanded-image generating processor that generates said expanded-image data corresponding to said magnifying power by applying a fluency transform to each arranged pixel in said original image data, said plurality of pixels in each block being generated at pixel generating positions; a magnifying power inspector that inspects whether said magnifying power is odd numbered; and a shifting processor that shifts said pixel generating positions relative to each corresponding pixel of said original image data by a shifting-amount corresponding to said magnifying power such that each arranged pixel of said original image data is off-center with respect to said plurality of blocks, when said magnifying power is the odd numbered.
