    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: This is a film image input system wherein an image of the developed still photo film is made to focus on an image sensing plane of a charge coupled device through a taking lens to be converted into electric signals and the electric signals are input in a video monitor. The film image input system comprises: a zoom driving part for changing the image magnification of the taking lens; a scan mechanism for moving an image taking position on the film by the taking lens; and a control part for controlling the scan mechanism in such a manner that the moving speed of the scan mechanism is decreased with the increase in the image magnification of the taking lens and making the moving speed of a screen on the video monitor constant during scan. Furthermore, the control part can restrict the scan scope of the scan mechanism in accordance with the image magnification, satisfactorily display the scope being picked up at present on a display device, and return the scan position to the center of the film and return the image magnification to a predetermined standard magnification so that the film image in the whole frame can occupy the whole screen of the video monitor, upon receiving the standard reproduction command.

    Abstract: A method and apparatus for determining a predominant angle of orientation of an image with respect to a reference angle. A file of picture elements is generated which depicts the image with respect to the reference angle. The picture elements are projected onto a plurality of contiguous segments of imaginary lines at selected angles across the file. Each imaginary line is perpendicular to its associated direction of projection. The number of picture elements that fall into the segments for each projection are counted. An enhancement function is applied to the segment counts of each projection. The projection that generates the largest value of the enhancement function defines the angle of orientation of the image. The position of a document scanner or the document itself may be rotated to compensate for the detected skew.

    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.
