Abstract
A camera includes an image sensor and a lens assembly. The image sensor includes a pixel array. The pixel array includes imaging pixels arranged in rows and columns. The lens assembly is configured to focus imaging light from a wide field of view onto the image sensor. The lens assembly includes a plurality of lens elements. The lens elements are arranged from widest to narrowest.
Claims18
A camera comprising:
- an image sensor having a pixel array, wherein the pixel array includes imaging pixels arranged in rows and columns;
- and
- a lens assembly configured to focus imaging light from a wide field of view (FOV) onto the image sensor, the lens assembly substantially consisting of a plurality of lens elements including five or less lens elements, wherein the lens elements are arranged from widest to narrowest, a rear lens element in the plurality of lens elements being the widest of the lens elements and positioned closest to the image sensor, and a front lens element in the plurality of lens elements being the narrowest lens element positioned farthest from the image sensor, wherein the rear lens element and a lens element that is next to the rear lens element each have a lensing surface that is concave aspherical on an object-side along a central optical axis of the lens assembly and wherein the wide FOV of the lens assembly is greater than 130 degrees.
A Head Mounted Display (HMD) comprising:
- a display configured to provide display light to an eye of a user of the HMD;
- and
- a camera including:
- an image sensor having a pixel array, wherein the pixel array includes imaging pixels arranged in rows and columns;
- and
- a lens assembly configured to focus imaging light from a wide field of view (FOV) onto the image sensor, the lens assembly substantially consisting of a plurality of lens elements including five or less lens elements, wherein the lens elements are arranged from widest to narrowest, a rear lens element in the plurality of lens elements being the widest of the lens elements and positioned closest to the image sensor, and a front lens element in the plurality of lens elements being the narrowest lens element positioned farthest from the image sensor and wherein the rear lens element and a lens element next to the rear lens element each have a lensing surface on an object-side that is concave aspherical along a central optical axis of the lens assembly and wherein the wide FOV of the lens assembly is greater than 130 degrees.
