Abstract:
A method for driving an image forming apparatus to form an image at a first two-dimensional resolution based on image data provided at a second two-dimensional resolution that is lower than the first two-dimensional resolution, the first and second two-dimensional resolutions each including a resolution in each of a fast-scan direction and a resolution in a slow-scan direction, the fast-scan direction resolution of the first two-dimensional resolution being higher than the fast-scan direction resolution of the second two-dimensional resolution and the slow-scan direction resolution of the first two-dimensional resolution being higher than the slow-scan direction resolution of the second two-dimensional resolution, the method comprising:receiving image data at the second two-dimensional resolution corresponding to an edge within an image;generating edge position information at the first two-dimensional resolution from the second two-dimensional resolution image data corresponding to an edge; andconverting the edge position information to drive values at the first two-dimensional resolution for driving at least one image forming element of the image forming apparatus.
