Abstract
The invention is relates to systems and methods for high dynamic range (HDR) image capture and video processing in mobile devices. Aspects of the invention include a mobile device, such as a smartphone or digital mobile camera, including at least two image sensors fixed in a co-planar arrangement to a substrate and an optical splitting system configured to reflect at least about 90% of incident light received through an aperture of the mobile device onto the co-planar image sensors, to thereby capture a HDR image. In some embodiments, greater than about 95% of the incident light received through the aperture of the device is reflected onto the image sensors.
Claims17
A device for high dynamic range (HDR) image capture, the device comprising:
- at least first and second co-planar image sensors fixed to a substrate;
- an optical splitting system comprising a beamsplitter configured to
- (i) transmit at least about 90% of incoming light received through an aperture of said device along a first path that gets reflected onto the first image sensor, and
- (ii) reflect a remainder of the incoming light along a second path that gets reflected back through the beamsplitter and onto the second image sensor,
- wherein the first and second paths have substantially the same length whereby the first and second image sensors simultaneously capture images that are identical but at different light levels;
- and
- an HDR processing system configured to process said two images to form a high dynamic range image.
A high dynamic range (HDR) camera comprising:
- at least first and second co-planar image sensors;
- and
- a beamsplitter configured to
- (i) transmit at least about 96% of incoming light received through an aperture of said device along a first path that gets reflected onto the first image sensor, and
- (ii) reflect a remainder of the incoming light along a second path that gets reflected back through the beamsplitter and onto the second image sensor,
- wherein the first and second paths have substantially the same length whereby the first and second image sensors simultaneously capture images that are identical but at different light levels.
