摘要： A dual-slope light guide includes a first surface, a second surface and a curved surface. The first surface has first reflecting structures. The second surface, connected to the first surface, has second reflecting structures. An included angle between the first surface and the second surface is unequal to 180 degrees. The curved surface connects the first surface to the second surface. The first surface, the second surface and the curved surface extend from a first end of the light guide to a second end of the light guide. A light beam incident to the first end of the light guide is reflected and converted by the first reflecting structure and the second reflecting structure into linear light emitted from the curved surface. A light source module and an optical assembly for a scanner are also disclosed.

摘要： A backlight controlled closeup photographing system is proposed, which is designed for use with a multimedia-capable information platform, such as an MMV (MultiMedia Viewer) device, to allow the user to photograph a small object, such as a business card, at close range with intensified illumination on the object for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. The proposed backlight controlled closeup photographing system is characterized by the use of backlight control to increase the intensity of the backlight illumination on the object being photographed for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. Since the intensity of illumination on the object can be increased without using flash unit, the invention is apparently more cost-effective and advantageous to use than prior art.

摘要： A transparency adaptor is described that includes a flat panel illuminator within the scanner lid of the scanner. The flat panel illuminator provides backlighting for scanning transparencies, such that light passes through the transparency only once and into the scanner optics within the scanner base. When the flat panel illuminator is lit during a scanning process, the light source within the scanner is not lit. In a second embodiment, the flat panel illuminator is removeably attached to the scanner lid. Another alternative is for the flat panel illuminator adapter to be a separate from the scanner, such that it is placed over a transparent document when needed, either plugging into the scanner or a separate power source during the scanning process.

摘要： An optical scanner consists of a plurality of linear scanning light sources, a plurality of scattering lens boards, a plurality of linear image capturing units and a plurality of converging lens boards. The linear scanning light sources and image capturing units are laid in a staggered fashion on a circuit board to form a plane about the size of the scanning object. The scattering lens boards scatter light for the light sources to project evenly on the scanning object. The converging lens boards converge image reflecting from the scanning object to facilitate the linear image capturing units to capture the object image.

摘要： A line-focus system with a curved fluorescent bulb for directing light from the curved fluorescent bulb toward the scan line in the line-focus system. The curved fluorescent bulb is shaped in such a manner that the light intensity across the photosensor line array in the line-focus system is relatively uniform and the length of the light bulb is shorter than straight light bulbs with end sockets at both ends of the light bulb. The curved fluorescent bulb may be C-shaped, U-shaped or towel bar-shaped.

摘要： An array of pixels of a solid-state imaging sensor having a rolling shutter is sequentially exposed to capture images from an illuminated target over successive frames for image capture by an imaging reader. The target is illuminated at a peak output power level for a fractional time period of a frame, and is not illuminated for at least a portion of a remaining time period of the frame for increased energy efficiency. Only a sub-array of the pixels is exposed during the fractional time period in which the target is being illuminated at the first output power level.
