摘要: Imager arrays, array camera modules, and array cameras in accordance with embodiments of the invention utilize pixel apertures to control the amount of aliasing present in captured images of a scene. One embodiment includes a plurality of focal planes, control circuitry configured to control the capture of image information by the pixels within the focal planes, and sampling circuitry configured to convert pixel outputs into digital pixel data. In addition, the pixels in the plurality of focal planes include a pixel stack including a microlens and an active area, where light incident on the surface of the microlens is focused onto the active area by the microlens and the active area samples the incident light to capture image information, and the pixel stack defines a pixel area and includes a pixel aperture, where the size of the pixel apertures is smaller than the pixel area.

摘要: Systems and methods in accordance with embodiments of the invention implement modular array cameras using sub-array modules. In one embodiment, an X×Y sub-array module includes: an X×Y arrangement of focal planes, where X and Y are each greater than or equal to 1; and an X×Y arrangement of lens stacks, the X×Y arrangement of lens stacks being disposed relative to the X×Y arrangement of focal planes so as to form an X×Y arrangement of cameras, where each lens stack has a field of view that is shifted with respect to the field-of-views of each other lens stack so that each shift includes a sub-pixel shifted view of the scene; and image data output circuitry that is configured to output image data from the X×Y sub-array module that can be aggregated with image data from other sub-array modules so that an image of the scene can be constructed.
