Patent ID: 11893668
Assignee: LEICA CAMERA AG
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 11:
12. An imaging system, comprising:
a plurality of electronic profiles of combinations of full-frame cameras and lenses stored in an electronic memory; and
a mobile electronic device configured to obtain image information via an electronic sensor of the mobile electronic device;
wherein the mobile electronic device is configured to generate, via an electronic control unit of the mobile electronic device, a final digital image via applying a profile of the plurality of electronic profiles to the image information;
wherein the image information includes color information and depth information;
the depth information includes a depth map,
wherein generating the final digital image includes:
identifying a focus area in the depth map;
converting the depth map to a blur radius map;
applying guided upscaling to the blur radius map;
quantizing the upscaled blur radius map to the closest indices in PSF information of the profile;
preprocessing the PSF information;
looking up front and back neighbor PSFs in the PSF information for the quantized upscaled blur radius map;
calculating residual interpolation factors;
modifying the neighbor PSFs;
converting the image information to a linear tone curve;
applying a per-pixel render procedure based, at least in part, on the converted image information and the modified PSFs, to provide an intermediate image;
restoring the tone curve for the intermediate image; and
blending back sharp pixels in the foreground of the intermediate image to generate the final digital image.
