A camera array, an imaging device and/or a method for capturing image that employ a plurality of imagers fabricated on a substrate is provided. Each imager includes a plurality of pixels. The plurality of imagers include a first imager having a first imaging characteristics and a second imager having a second imaging characteristics. The images generated by the plurality of imagers are processed to obtain an enhanced image compared to images captured by the imagers. Each imager may be associated with an optical element fabricated using a wafer level optics (WLO) technology.

An image reading device includes a plurality of light-receiving pixels configured to receive reflected light; a first light-shielding member including a plurality of first openings and disposed between the plurality of light-receiving pixels and a reference surface; a second light-shielding member including a plurality of second openings and disposed between the plurality of first openings and the reference surface; and a plurality of condenser lenses disposed at a distance from the plurality of second openings. The plurality of condenser lenses, the second light-shielding member, the first light-shielding member, and the plurality of light-receiving pixels are disposed at positions at which reflected light sequentially passes through one of the condenser lenses corresponding to each light-receiving pixel, one of the second openings corresponding to the each light-receiving pixel, and one of the first openings corresponding to the each light-receiving pixel and enters the each light-receiving pixel.

There is disclosed an apparatus and method of aligning content put through a duplex scanner. By performing operations on data extracted from physical documents, digital documents that would otherwise appear skewed can be un-skewed. The process compares two images, e.g. a front and a back page for a document, and determines how they are offset from one another. The process uses a projection profile error minimization technique to calculate a translation for one or both pages to digitally align the margins for a digital document such that the margins match.

A digital microform imaging apparatus includes a bracket movably coupled to a chassis. A microform media support is coupled to the bracket and includes a frame and a window supported by the frame. An illumination source is provided to direct light through the window of the microform media support along an optical axis. An optical sensor is positioned along the optical axis. A motor is operatively engaged with the microform media support to move the bracket and frame relative to the chassis along an axis perpendicular to the optical axis.

An optical device includes: a lens body having multiple lenses arranged such that optical axes thereof are parallel to one another; a light-shielding wall that is disposed for the lens body and blocks, in an optical axis direction, portion of light directed to the multiple lenses; and a sheet member that covers a surface of the light-shielding wall, the surface being perpendicular to the optical axes, and allows light to pass therethrough.

A sensor array assembly including a first sensor array, a second sensor array and a mounting substrate. The first sensor array includes a first process direction width and a first photosite, while the second sensor array includes a second process direction width and a second photosite. The first and second sensor arrays are separately secured on the mounting substrate. The first photosite is in precision alignment with the second photosite.
