Abstract: A scan assisting fixing device and a scanner using the same are provided. The fixing device is for fixing an object to be scanned, which includes a scanning portion and a holding portion. The fixing device includes an accommodation region, a scan window and a protrusion portion. When the holding portion is loaded in the accommodation region, the scanning portion correspondingly disposed in the scan window is retained and fixed by the protrusion portion, and the position of the holding portion in the fixing device is constant, so that the scanning portion is always within the range of the field depth of the scanner regardless of the specification of the positive film holder, and the clarity of the scanned image is assured.

Abstract: The invention is directed to a scanning device including an image sensing module, a first carrier, a second carrier and a holder. The image sensing module includes an image sensor for reading the image of an original document. The first carrier is for carrying the original document in a dynamic scanning mode. The second carrier is for carrying the original document in a static scanning mode. The holder, used for fixing the first carrier and the second carrier, includes a transitional portion disposed between the first carrier and the second carrier. There are a first distance between the image sensor and the bottom surface of the first carrier and a second distance between the image sensor and the bottom surface of the second carrier, wherein the first distance is greater than the second distance. The dual-mode design facilitates the assembly of carriers and avoids the dust entering the scanning device.

Abstract: The invention relates to a lighting structure and a scanning device. The lighting structure comprises a light source and a light guide. The light source comprises a plurality of light emitters spaced within a first plane along a first direction. The light guide comprises a plurality of light guiding bodies arranged in parallel. The light guiding bodies form a one-to-one correspondence with the light emitters and have a light entering surface and a light leaving surface which are both a curved surface. The curve of the intersection between each light leaving surface and a first cross-section has a first curvature radius, and the curve of the intersection between each light entering surface and a second cross-section has a second curvature radius, wherein the first cross-section is perpendicular to the second cross-section, and the first cross-section and the second cross-section are both perpendicular to the first plane.

Abstract: A power saving method for a digital frame is provided, wherein the digital frame includes a sensor for object detection within a specific area near the digital frame. When no entity is detected by the sensor within the specific area for a predetermined time period, the digital frame automatically switches to a power down mode for saving power consumption.

Abstract: Printed circuit boards are provided. A printed circuit board includes a main body and an anti-EMI coating. The main body includes a substrate and a conductor connected to an electronic component on the substrate. The anti-EMI coating is formed on the substrate or the conductor by printing, plating or deposition, to prevent EMI.

Abstract: An image capturing method and an image-capturing device thereof are provided. Firstly, a dividing rule for dividing a first part and a second part is set, such that the positions and sizes of the first and the second parts are obtained accordingly. Next, a first resolution corresponding to the first part and a second resolution corresponding to the second part are set respectively. Then, the positions and sizes of the first and the second parts, the first resolution and the second resolution are recorded in a reference table. Next, an image of an object is captured to obtain a multi-resolution analog signal. Then, the multi-resolution analog signal is transformed to a multi-resolution digital signal. After that, a first part image corresponding to the first part and a second part image corresponding to the second part are respectively obtained with reference to the multi-resolution digital signal.

Abstract: A method for capturing a pattern, which is printed on a print medium and contains a holographic image, includes providing an image-capturing device comprising a light source for emitting light onto the print medium and a light-sensing component for receiving light reflected from the print medium, adjusting a disposition of the print medium, the light source, and the light-sensing component and equivalently locating the light-sensing component in a blind zone where the light-sensing component will not receive light reflected from the holographic image of the pattern, and capturing the pattern with the light source and the light-sensing component.

Abstract: A method for calibrating an image-scanning module scanning a reference sheet to produce an image is presented. The image-scanning module has a first midpoint, and the reference sheet has a target label. A first label corresponds to a first end of the reference sheet, and a second label corresponds to a second end of the reference sheet. The calibration works out by comparing the actual positions of the first midpoint, the target label, the first label, and the second label with their corresponding coordinate values on the image obtained from scanning the reference sheet.
