WAFER LEVEL CAMERA HAVING MOVABLE COLOR FILTER GROUPING

摘要

An image capture unit includes an image sensor and a lens structure disposed proximate to the image sensor to focus an image onto the image sensor. A movable color filter grouping is disposed over the lens structure. The movable color filter grouping includes a plurality of N color filters arranged therein such that all light that is incident upon the image sensor through the lens structure is directed through only one of the plurality of N color filters of the movable color filter grouping per each exposure of the image sensor. A positioning device is attached to the movable color filter grouping to reposition the movable color filter grouping such that substantially all of the light that is incident upon the image sensor through the lens structure is directed through a different one of the plurality of N color filters for each successive exposure of the image sensor.

1. An image capture unit, comprising:
an image sensor including a pixel array having a plurality of pixel cells arranged therein; a lens structure disposed proximate to the image sensor to focus an image onto the image sensor; a movable color filter grouping disposed over the lens structure, wherein the movable color filter grouping includes a plurality of N color filters arranged therein such that all light that is incident upon the image sensor through the lens structure is directed through only one of the plurality of N color filters of the movable color filter grouping per each exposure of the image sensor; and a positioning device attached to the movable color filter grouping to reposition the movable color filter grouping between each exposure of the image sensor such that substantially all of the light that is incident upon the image sensor through the lens structure is directed through a different one of the plurality of N color filters for each successive exposure of the image sensor.
