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

Claim 0:
1. A method of generating a digital image, the method comprising:
obtaining a profile of a combination of a full-frame camera and a lens;
obtaining image information from an electronic sensor of a mobile electronic device;
generating, via an electronic control unit of the mobile electronic device, a final digital image via applying the profile to the image information;
wherein the image information includes color information and depth information;
wherein 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 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.
