GENERALIZED ASSORTED PIXEL CAMERA SYSTEMS AND METHODS

摘要

Generalized assorted pixel camera systems and methods are provided. In accordance with some embodiments, the generalized assorted pixel camera systems include a color filter array, where the color filter array includes a plurality of primary filters and a plurality of secondary filters. Each filter has a particular spectral response and each filter is formed on a corresponding pixel of a plurality of pixels. Each of the plurality of primary filters and the plurality of secondary filters enhances an attribute of image quality and the information obtained using the plurality of primary filters and the plurality of secondary filters is used to balance spectral resolution, dynamic range, and spatial resolution for generating an image of a plurality of image types.

主权项

1. A color filter array, comprising:
a plurality of first color filters each having a first spectral response; a plurality of second color filters each having a second spectral response that is different from the first spectral response; a plurality of third color filters each having a third spectral response that is different from the first spectral response and different from the second spectral response; and a plurality of fourth color filters each having a spectral response that is highly correlated with at least a portion of the first spectral response, the second spectral response or the third spectral response, wherein the plurality of fourth filters includes at least four filters that each have a different spectral response; wherein each of the plurality of first color filters are arranged such that the first color filter is adjacent to a second color filter and a third color filter, each of the plurality of second color filters are arranged such that the second color filter is adjacent to two first color filters and a fourth color filter, each of the plurality of third color filters are arranged such that the third color filter is adjacent to two first color filters and a fourth color filter, and each of the plurality of fourth color filters is arranged such that the fourth color filter is adjacent to two second color filters and two third color filters, and spaced apart from another fourth color filter having the same spectral response by at least three color filters along two orthogonal directions of the color filter array.
