| 20110063695 | SHEETFED FILM SCANNING CORRECTION METHOD - A sheetfed film scanning correction method includes: using a film holding member as a film feeding carrier, wherein after the film holding member is inserted into a work position in a scanner, a scanning module of the scanner collects a first correction information under a filmless scanning state and corrects a subsequent scan result according to the first correction information; and setting sheet-feeding rollers of the scanner in idle running as if under a real film scanning state during or prior to collection of the first correction information. By film scanning simulation, the backlight distribution information under the filmless state is real-time collected and used as a correction information, hence implementing the collection of most accurate scan correction information as if under a real scanning environment, particularly applicable to the portable sheetfed film scanner, and eliminating impacts on the correction information caused by temperature change or physical vibration. | 03-17-2011 |
| 20110063600 | FILM HOLDER - A film holder is provided. During scanning of a to-be-scanned object, the film holder is inserted into a scanning device. The film holder includes an input portion, a guiding portion and an information window. The input portion has an entrance, a channel and an exit, the channel disposed between the entrance and the exit. During scanning of the to-be-scanned object, the to-be-scanned object passes through the channel. The guiding portion connects to the input portion for guiding the to-be-scanned object. The information window is formed at and through the guiding portion. During scanning of the to-be-scanned object, the side regions of the to-be-scanned object pass through the information window. Functions of the scanning device are effectively augmented; the film is kept from being scratched; the quality of image scanning is kept from being deteriorated; and it is convenient to use the scanning device. | 03-17-2011 |
| 20110063599 | FILM HOLDER - A film holder is provided. During scanning of a to-be-scanned object, the film holder is inserted into a scanning device. The film holder includes an input portion, a guiding portion and a leveling portion. The input portion has an entrance, a channel and an exit, the channel disposed between the entrance and the exit. During scanning of the to-be-scanned object, the to-be-scanned object passes through the channel. The guiding portion connects to the input portion for guiding the to-be-scanned object. The leveling portion is disposed on one side of the channel. During scanning of the to-be-scanned object, the leveling portion leans against the to-be-scanned object. The sensing unit stably senses the to-be-scanned object. The to-be-scanned object inside the film holder is kept from being scratched and the to-be-scanned object is in smooth move during scanning. | 03-17-2011 |
| 20110032580 | SCANNING DEVICE AND SCANNING METHOD THEREOF - A scanning device and a scanning method thereof are provided. The scanning device includes a scanning group, a paper-feed roller and a calibration portion. The scanning group includes a line light source generating module and a scanning module. The line light source generating module includes a point light source, a light-guiding plate and a casing. The light emitted by the point light source along a first direction is converted into a line light source through a light-guiding plate disposed in the casing. The light emitted by the line light source along a second direction is emitted from an opening of the casing. The scanning module, along the first direction, includes a scan document region and a calibration region. The light reflected through the to-be-scanned document is received in the scan document region. The calibration portion disposed on the casing or the paper-feed roller corresponds to the calibration region. | 02-10-2011 |
| 20100296741 | FILM SCANNING METHOD - A film scanning method including the following steps is provided. Firstly, a film including an identification code and an image information area is provided, wherein the identification code is disposed on one side of the image information area along a first direction and has a first identification end and a second identification end along a second direction. Next, a location information of the identification code and a sequence information of the first identification end and the second identification end are checked and recorded. Lastly, the scanned image is adjusted along the first direction and the second direction respectively according to the location information and the sequence information. The invention provides the user with convenience in using a film scanning device without using additional elements. | 11-25-2010 |
| 20100253984 | SHEET-FED IMAGE SCANNING METHOD AND SCANNING DEVICE THEREOF - A sheet-fed image scanning method and a scanning device thereof are provided. Firstly, a contact image sensor (CIS) scanning element is equipped with at least two sheet-feeding rollers respectively and passively connected with a driven roller, so that the to-be-scanned sheet is fed into/out between the sheet-feeding rollers and the driven rollers. Then, the to-be-scanned sheet is scanned by the CIS scanning element when the to-be-scanned sheet is fed in, and the driven roller is elastically ascended or descended according to the thickness of the to-be-scanned sheet. The invention enables non-contact or low-friction contact scanning between the scan glass window of the scanning device and the to-be-scanned sheet to avoid the to-be-scanned sheet being scratched or damaged and assure the constant-distance scanning to obtain high-quality scanned image. The position of the scanning element can be adjusted to the optimum scanning focal distance according to the thickness of the to-be-scanned sheet. | 10-07-2010 |
| 20100039683 | SCANNING METHOD AND AUXILIARY APPARATUS OF AUTO-EXECUTING APPENDING SCANNING FUNCTION - A scanning method and an auxiliary apparatus of auto-executing appended scanning function are disclosed. A specific image, which can be identified by a scanning module of a scanning device, is first loaded on a scanned document or a scanned document carrier, and an appended function denoted by the specific image is predetermined in a processing module of the scanning device. Then, as the scanning device scans the scanned document or the scanned document carrier with the specific image, the scanning device automatically executes the predetermined appended scanning function or processing function according to the scan data of the specific image. The invention can be applied to all kinds of portable scanning device, and especially can be applied to small-sized portable scanning devices for scanning photos, name cards, and so on to realize the direct display and connection with a display device or a storage device. | 02-18-2010 |
