Abstract:
A contact image sensor module for scanning a document includes a light source, a photosensing array and a lens assembly. The light source emits a light beam to the document, thereby generating an optical signal. The photosensing array is used for converting the optical signal into an electronic signal. The lens assembly is used for focusing the optical signal reflected from the document and imaging the optical signal onto the photosensing array. The photosensing array includes a first photosensing element with a first width and a second photosensing element with a second width. The first width is greater than the second width.

Abstract:
A focus adjusting device (50) for an image sensor (1) is provided for ensuring precise focusing of the image sensor. The focus adjusting device includes a contact element (51) in direct contact with the bottom of a scanner cover plate, a focus varying element (53) engaging with the contact element, and a focus fine adjusting element (55) movably mounted on a housing of the image sensor. The focus varying element and the contact element are driven to correspondingly move vertically together with the vertical movement of the focus fine adjusting element, whereby the distance between an upper surface of the housing and the bottom of the cover plate is thus changed for precise focusing.
Abstract:
This invention has as its object to provide an image sensor which can effectively attain higher read resolution, and an image processing apparatus and information processing system using the same. To achieve this object, function members including a light source (6) for irradiating an object to be read (PP) with light, a sensor (3) for receiving light reflected by the object to be read (PP), and an imaging element (7) for forming an image of the reflected light on a light-receiving portion of the sensor (3) are attached to and supported by a support member (1) to have a predetermined positional relationship. In order to assure high attachment positional precision and rigidity for the function members, the support member (1) is formed to have a hollow shape. The support member (1) is formed to have the hollow shape along its longitudinal direction. Two side portions of the support member (1) are formed to have a hollow shape, and are coupled at end portions in the longitudinal direction.
Abstract:
A multichannel video receiver having an analog-to-digital converter, fast-Fourier transform circuit and inverse-Fourier transform circuit. The analog-to-digital converter circuit generates a digitized representation of a frequency band used to convey a plurality of video signals, and the fast-Fourier transform circuit generates a frequency-domain representation of the digitized representation of the frequency band. The inverse-Fourier transform circuit recovers, from the frequency-domain representation, a plurality of digitized time-domain signals that correspond to the plurality of video signals.

The light source module structure includes a housing having a first circuit board therein; a light-sensing element disposed on the first circuit board and electrically connected to the first circuit board; a lens disposed in the housing and being parallel to the light-sensing element; and at least one organic electro luminescent element integration disposed in the housing to provide a light source.
Abstract:
An optical scanner system wherein the central region of the light source is selectively covered up by a mechanically actuated shutter during a transparency scanning mode. By occluding the central portion of the light source, problems with flare and degraded image quality are eliminated. The shutter is actuated to its two positions (normal reflective mode position, transparency mode position) by pins, protrusions, or the scanner walls in the scan module path. When the scan module is driven to the extremes of its travel the shutter is either driven open or closed. A bracket structure is provided to hold the transparent media and a covering light reflective tent, and can include the pin or pins that can protrude into the scanner module path and thus actuate the shutter only when the structure is mounted on to the scanner by the user. The bracket structure can include a lower member that rests directly on the platen glass to align filmstrips, slides, and other transparent media. The tent structure is hinged relative to the lower structure which allows it to be opened and closed to enable insertion of transparent media. When the tent structure is closed it acts as the reflective light path to allow light from the primary light source to be reflected up, over, and down through the transparent media, and into the optical light path leading to the optical sensor.

Abstract:
A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1′, A2′), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1′, A2′). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).
