| 20120075680 | SCANNING SPEED CONTROL DEVICE AND METHOD - A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device. | 03-29-2012 |
| 20120044545 | METHOD FOR AUTOMATICALLY IDENTIFYING SCAN AREA - In accordance with the present invention, a method for automatically identifying a scan area by a scanner is disclosed. The method comprises steps of scanning an original comprising an object, identifying the original to establish a location and a profile of the object in the original, displaying a preview window corresponding to the original, wherein a location and a profile of a confined area is exactly the location and the profile of the object, receiving a framed area selected from the preview window by user, wherein a portion of the framed area beyond the confined area is automatically removed to generate a scan area, and scanning the scan area. The present invention can also extend to a method for selecting a scan area by a user and a scanner with a feature of automatically identifying a scan area. | 02-23-2012 |
| 20110090539 | IMAGE CORRECTION METHOD, APPARATUS, ARTICLE AND IMAGE - An image correction method able to avoid error image. According to opposite properties of black and white, only the last few bits of the scanned digital signal are extracted for black correction, while only the first few bits of the scanned digital signal are extracted for white correction. Further, the most significant bit of the digital signal is 1 for white correction. Therefore, the unwanted LBB effect on the scanned image caused by dust or spots on the correction document is avoided. In addition, as only a few bits of the scanned digital signal are extracted, the requirement in memory capacity is reduced. | 04-21-2011 |

| 20100134856 | METHOD FOR SELECTING AND ADJUSTING SCANNER ILLUMINANT - A scanner includes a first illuminant device having a first power associated therewith, and a second illuminant device having a second power associated therewith. The first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document. The scanner is configured to select one of the first illuminant device and the second illuminant device based, at least in part on, a level of power supplied to the scanner via a power source, and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device. | 06-03-2010 |
