Abstract
An apparatus includes an image-processing-unit that generates tag information indicating whether each of pixels of a first-resolution image data is a pixel of a character or a line, a resolution-converting-unit that converts the first-resolution image data to image data with a second resolution higher than the first resolution, and a light-source-driving-unit that drives light-source according to the second-resolution image data. The resolution-converting-unit includes an image-matrix-acquiring-unit that acquires an image matrix being image data and tag information with the first resolution in an area containing a target-pixel and pixels around the target-pixel, a pattern-matching-unit that determines whether the target-pixel is a pixel of an edge of a character or a line based on the image matrix, and a first-converting-unit that, when the pixel is the edge pixel, converts the image data to image data with the second resolution of a pattern determined in accordance with a layout of the target-pixel.
