Abstract:
1. An imaging device comprising: an image sensor including: a first lens that includes a first array of microlenses having a first focal length, wherein the first array of microlenses is configured to focus image light from a first focus distance onto the first group of pixels; and a second lens that includes a second array of microlenses having a second focal length different from the first focal length, wherein the second array of microlenses is configured to focus the image light from a second focus distance onto the second group of pixels and not the first group of pixels, and wherein the first lens is positioned to focus the image light from the first focus distance onto the first group of pixels and not the second group of pixels, the first focus distance being different than the second focus distance, and further wherein first microlenses of the first array of microlenses are intermixed with second microlenses of the second array of microlenses in a repeating pattern and the first group of pixels is intermixed with the second group of pixels to correspond with the first and second microlenses intermixed in the repeating pattern.
