An expanded-image generating apparatus is provided for 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 When the magnifying power regarding at least one of a direction along width and a direction along length in the original image data is set, a pixel arranging processor arranges each pixel in the original image data at a position corresponding to a center position of each of the plurality of blocks in accordance with the magnifying power. The expanded-image data corresponding to the magnifying power is generated at pixel generating positions corresponding to the each block by applying a fluency transform to each pixel in the original image data at the position. When the magnifying power is odd numbered, a shifting processor 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.
