| 20080266611 | Image Processing Device and Image Processing Method - An image processing device scans a document and judges a background color of the scanned document based on a stored threshold. The threshold necessary for background color judgment is reset when the judgment result is not determinable, and the background color is re-judged based on the reset threshold. Image processing is performed according to the judgment result. | 10-30-2008 |
| 20080266612 | Image Processing Device and Image Processing Method - An image processing device detects a candidate area of a background color in a chromaticity plane with respect to an original scanned document. A background color area is determined based on the candidate area of the detected background color. Boundary lines extending from the determined background color area to an achromatic-color area are generated. The background color area and an area surrounded by the background color area and the boundary lines are set as a mask, and the background color of the original document is deleted. | 10-30-2008 |
| 20080266613 | Image Processing Device and Image Processing Method - An original document is scanned, an arbitrary color area in a chromaticity plane is extracted with respect to the scanned original document, coordinate conversion is performed on the extracted color area in the chromaticity plane, and a mask area is determined to be masked, in accordance with the converted color area on which the coordinate conversion has been performed. | 10-30-2008 |
| 20090091801 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - An image forming apparatus and a control method thereof include an adaptive threshold, which can be adapted for every block dividing an entire scanned region of a document, is set. A brightness value of original brightness data of the document is disregarded, and is substituted by a brightness value of background color data corresponding to the block, by use of a brightness threshold and a color difference threshold set as the adaptive threshold based on difference between brightness of the blocks and difference between color differences of the blocks. Accordingly, there is no problem of back surface noise such that an undesired object of a back surface of the duplex-printed document appears on a scan image in scanning a front surface of the document. | 04-09-2009 |
