Abstract:
An optical system for an internal drum readout apparatus is disclosed. The optical system includes a hollow cylindrical segment defining a central axis, a support structure configured and adapted to translate along the central axis, a mirror mounted on the support structure for translational movement therewith and for rotational spinning around the central axis, a light source mounted to the support structure for providing a beam capable of being directed along the central axis which in turn is directed against the medium thereby producing a stimulated light, a detector coaxially aligned with the central axis, the detector being configured and adapted to absorb stimulated light direct toward and reflected off of the angled mirror, and a shroud (200) mounted on the support structure for blocking stimulated light not directed toward the angled mirror, wherein the stimulated light not directed toward the angled mirror would otherwise degrade the medium prematurely.
Abstract:
Die Erfindung betrifft ein Verfahren zur Signalauswertung eines elektronischen Bildsensors der eine Oberfläche mit einer Vielzahl von lichtempfindlichen Pixel aufweist, wobei jeder Pixel in Abhängigkeit des an der entsprechenden Pixelposition empfangenen Lichteingangssignals ein elektrisches Ausgangssignal abgibt, dessen Stärke mit dem Lichteingangssignal korreliert und in einer Auswerteeinheit als Bildinformation auswertbar ist.
Abstract:
PURPOSE: An image reading apparatus is provided to suppress a change of return resistance of a manuscript in a manuscript reading area, thereby restricting return speed of the manuscript. CONSTITUTION: A through hole(263) of a protrusion unit of a depth side of a manuscript return unit(250) is inserted into a pin of a depth-sided end part of a reinforcing member(230). A depressed part(273) of a protrusion unit of the front side of the manuscript return unit is inserted into a pin of a front-sided end part of the reinforcing member. Therefore, the manuscript return unit is horizontally positioned for the reinforcing member. The manuscript return unit can move upward/downward in the range of the interval between the protrusion unit and the head of a screw.
Abstract:
CIS(밀착형 이미지 센서)를 스프링에 의해 가압해서 접촉부재(2)를 원고지지 유리(즉, 원고대)의 하부면에 접촉시킨 화상판독장치에 있어서, 상기 접촉부재가 CIS의 주주사 판독범위내에, 구체적으로는, 주주사 판독범위의 양단부에 대한 원고지지 유리의 굴곡량이 최대 굴곡량의 약 1/2이 되는 위치에 배치되어 있다. 따라서, 원고지지 유리가 휘었을 때, CIS는, 원고대의 굴곡이 없는 경우의 위치로부터, 원고지지 유리의 주주사 판독범위에 있어서의 최대 굴곡량의 약 1/2만큼 스프링 힘에 대항해서 눌러 내릴 수 있어, CIS의 최적 초점 위치가 아래쪽으로 어긋나게 되어, 결과적으로, 원고면을 구성하는 원고지지 유리의 상부면은, 주주사 판독 범위의 전역에 있어서 CIS의 유효초점범위(초점심도)안에 유지됨으로써, 고품위의 화상 판독을 행하는 것이 가능해진다.

Abstract:
A method includes invoking an image capture interface via a mobile device; and analyzing video data captured via the capture interface. The analysis includes determining whether an object exhibiting one or more defining characteristics is depicted within the viewfinder; and if so, whether that object satisfies one or more predetermined quality control criteria. The method further includes displaying an indication of success or failure to satisfy the predetermined control criteria on the mobile device display. Where the object depicted within the viewfinder satisfies the one or more predetermined quality control criteria, the method also includes: displaying an indication that the object depicted in the viewfinder exhibits the one or more defining characteristics; automatically capturing an image of the object; and/or automatically storing to memory one or more of the frames in which the object is depicted in the viewfinder. Systems and computer program products are also disclosed.
Abstract:
A camera assembly for generating high resolution photograph includes a sensor assembly that has two regions of different effective resolution. Image data from multiple images that are captured with the sensor assembly are combined to generate output image data in the form of a high resolution picture. A first region of the sensor is used to capture image data for the images that are combined. A second region, that is of higher effective resolution than the first region, is used to capture image data for use in aligning the image data from the plural images prior to combination.
Abstract:
An image capture device (2) includes a sensor (4) having an active area comprising a plurality of pixels (6) and a shutter array (8) for controlling the exposure of individual pixels. The pixels are grouped in a plurality of pixel subsets and are arranged to capture a plurality of time-separated lo-res images, which can be viewed sequentially as a movie or combined to form a hi-res still image.
Abstract:
An image reading apparatus including: a supply device for supplying sheets to a reading position, a platen glass plate in the reading position, a platen roller opposed to the platen glass plate, a reading device for exposing a sheet on the platen glass plate to read an image on the sheet, and a white guide member upstream of the platen roller in the transporting direction, wherein a portion of the guide member closest to the platen roller is on the platen roller side with respect to a plane which includes the point in the outer periphery of the platen roller closest to the platen glass plate and which is parallel to the platen glass plate, and wherein the longitudinal length of the guide member is the same as or larger than the width of the range of the reading device.
Abstract:
A contact image sensor (CIS) (201) is incorporated into a drive belt (203) attached to the length of the CIS, resulting in a more compact scanning mechanism and in lighter and smaller scanning devices. The CIS (201) is forced to traverse the document by a drive mechanism (235) that pulls the entire belt and CIS across the document while maintaining the tension necessary to keep the document in the narrow depth of focus. This mechanism provides a uniform force on the CIS, reducing the possibility of yawing motion, and keeps the document in focus through the tension on the drive belt. The combined CIS and transport mechanism power requirements can be supplied by standard computer interfaces. The mechanism also hides the internal workings of the scanner behind a drive belt (203) that is the size of the platen window (301). The drive belt can either be printed with instructions or markings to indicate document placement, or left blank.
