Abstract
According to the present invention, an image processing apparatus includes an original image data input unit 11 for receiving the original low resolution image data; a connection detector 13 for detecting a connection of a target pixel in the original image data and neighboring pixels; a rule application unit 17 for employing a relationship between a coordinate position of a pixel in the original image data and a coordinate position of a resultant pixel in the expansion image data to define a plurality of types into which the relationship can be sorted, and for applying a specific rule for the plurality of types; and a results output unit 19 for determining the value of the resultant pixel in accordance with the rule, and for outputting the expansion image data, wherein, when the connection detector 13 ascertains that the target pixel constitutes a one-pixel width line, the rule application unit 17 applies a rule that will maintain the one-pixel width even in the expansion image data.
