Abstract:
A film video player (10) has film gates (14, 15) for mounting photographic film (F, F'). An imager has a lens (L) for projecting at least a portion of a film frame image from the film onto a sensor (S). The sensor converts an image to a video signal for video display. A zoom carriage (25) changes the magnification of the image with respect to the film frame image. A scan carriage (65) translates the sensor with respect to the film frame image in one axis, and a gear assembly (90) translates the sensor along a perpendicular axis as well as rotating it.
Abstract:
A system and method for processing an image of a document is disclosed. The method includes receiving at least one predetermined document parameter of the document. An image of the document is previewed on a display using a camera. The display provides a visual indication of a defect in the image based on the preview. A processor proposes a procedure to minimize the defect in the image. A user adjusts the camera in response to the proposal. The processor processes the image of the document.
Abstract:
Disclosed are embodiments of methods, systems, and apparatus for providing multiple image fields or regions on an imaging array. In certain preferred embodiments, a high density imaging array may be partitioned into two or more regions, each of which may be used to render a separate view of the scan volume. This arrangement may provide an increase in the effective scan volume beyond the volume available with a single imager having a single point of view and may allow for reading of encoded symbols at a variety of orientations that would otherwise preclude accurate imaging with a single imager.
Abstract:
A document platen. A support member supports an end portion of the document platen from below in a sub scanning direction. A sensor module has a first protruding portion protruding in the sub scanning direction. The sensor module includes a first sensor, and a second sensor being shorter than the first sensor in length and being housed into the first protruding portion. A transport unit transports the sensor module in the sub scanning direction. When the sensor module is transported to an end part in the sub scanning direction, the support member is housed into a space disposed at a side of the first protruding portion in a main scanning direction.
Abstract:
Bei dem Verfahren nach der Erfindung wird zunächst anhand von Informationen, die im auszuwertenden Objekt enthalten sind die Richtung der nachfolgenden Abtastung festgelegt. Anschließend wird das zur Datenaufnahme dienende Detektorarray so gedreht, daß seine Detektorzeilen senkrecht zu dieser Abtastrichtung stehen. Diese Wahl der Abtastrichtung kann automatisch oder interaktiv erfolgen. Zur eigentlichen Datenaufnahme wird das Objekt in der festgelegten Abtastrichtung streifenförmig über das feststehende Detektorarray bewegt. Die dabei vom Detektorarray erzeugten Signale werden in einem nachgeschalteten Rechner ausgewertet.
