Imaging device with a plurality of depths of field
Abstract:
An imaging device includes an image sensor that includes a first group of pixels and a second group of pixels disposed on a semiconductor die. The first group of pixels are arranged to capture a first image and the second group of pixels are arranged to capture a second image. The imaging device also includes a first lens configured to focus image light from a first focus distance onto the first group of pixels. The imaging device further includes a second lens configured to focus the image light from a second focus distance onto the second group of pixels and not the first group of pixels. 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 is different than the second focus distance.
