TONE MAPPING IN HIGH-RESOLUTION IMAGING SYSTEMS
This abstract first appeared for US patent application 20240257325 titled 'TONE MAPPING IN HIGH-RESOLUTION IMAGING SYSTEMS
Original Abstract Submitted
a method includes obtaining multiple image frames captured using at least one imaging sensor. the method also includes generating a local tone map, a global tone map look-up table (lut), and one or more contrast enhancement luts based on at least one of the image frames and one or more parameters of the at least one imaging sensor. the method further includes generating a blended and demosaiced image based on the image frames and generating a local tone mapped image based on the blended and demosaiced image and the local tone map. the method also includes adjusting color saturation based on the local tone mapped image to generate a corrected image. in addition, the method includes generating an output image based on the corrected image, the global tone map lut, and the one or more contrast enhancement luts.
