A novel image processing system includes a pixel position indicator and a pixel inserting unit. The pixel position indicator is configured to indicate insertion positions in the image data. The pixel inserting unit is configured to enlarge a size of the image data by inserting an additional pixel at each of the insertion positions and accordingly shifting the original pixels in a given direction. The additional pixel has a value lower than a given threshold. Each insertion position is at an approximate center of an area formed of pixels having values higher than the given threshold. A novel image forming apparatus incorporates such an image processing system and an electrophotographic system. The electrophotographic system is configured to form an image by irradiating a photoconductive surface with a laser beam according to the processed image data.

The present patent application claims priority under 35 U.S.C. §119 from Japanese Patent Application No. 2007-154631 filed on Jun. 12, 2007, the entire contents of which are hereby incorporated by reference herein in their entirety.
1. Field of the Invention
The present invention relates to an image processing system and an image forming apparatus incorporating same, and more particularly, to an image processing system that enlarges image size by inserting additional pixels in an original image, and an image forming apparatus incorporating such an image processing system.
A more complete appreciation of the disclosure and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
FIG. 1 is a schematic illustration of an example of a conventional scaling operation where image size is enlarged by adding new pixels;
FIG. 2 is a schematic illustration of an image forming apparatus according to one embodiment of this patent specification;
In describing exemplary embodiments illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the disclosure of this patent specification is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner and achieve a similar result.
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, exemplary embodiments of the present patent application are described.
FIG. 2 is a schematic diagram illustrating an image forming apparatus 100 according to one embodiment of this patent specification.
