By Targeted News Service

ALEXANDRIA, Va., Aug. 10 -- CSR Technology, San Jose, Calif., has been assigned a patent (8,237,813) developed by Haim Garten, Haifa, Israel, for a "multiple exposure high dynamic range image capture."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for creating a High Dynamic Range (HDR) image within a consumer grade digital camera from a series of images of a scene captured at different exposure levels, and displaying the HDR image on the camera's built-in display, are provided. The approach employs mixing images of the series to incorporate both scene shadow and highlight details, and the removing of "ghost" image artifacts appearing in the mixed HDR image resulting from movement in the scene over the time the series images are captured. The low computational resource utilization of the present invention's image mixing and ghost removal processing operations, along with the present invention's ability to commence image mixing and ghost removal prior to the acquisition of all series images, can significantly reduce the time required to generate and display a tone mapped HDR image."

The patent application was filed on April 20, 2010 (12/763,693). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,237,813&OS=8,237,813&RS=8,237,813
