Abstract

Claims (42)

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; and

generating, via an electronic control unit of the mobile electronic device, a final digital image by applying the selected full-frame profile to the image information so as to simulate the imaging characteristics of the full-frame camera and lens on the mobile device sensor data;

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;

wherein the full-frame camera includes a color sensor that has a larger area than an area of the electronic sensor of the mobile electronic device.

2 . The method of claim 1 , wherein the profile includes a point spread function.

3 . The method of claim 1 , wherein obtaining the profile includes operating the full-frame camera and the lens to generate a point spread function.

4 . The method of claim 3 , wherein operating the full-frame camera and the lens to generate the point spread function includes capturing one or more profile images of an electronic display.

5 . The method of claim 4 , wherein the electronic display displays a plurality of white circles on a black background; and the electronic display incudes an OLED display.

6 . The method of claim 1 , wherein the profile is obtained from an electronic library of profiles of respective combinations of full-frame cameras and lenses.

7 . The method of claim 6 , wherein the electronic library is stored on a memory of the mobile electronic device.

8 . The method of claim 6 , wherein the electronic library is stored on a remote server; and

obtaining the profile includes the mobile electronic device wirelessly communicating via a global computer network to access the profile from the electronic library.

9 . The method of claim 1 , wherein the mobile electronic device includes a cellular transceiver.

10 . The method of claim 1 , including deleting or ignoring default profile information of the mobile electronic device.

11 . The method of claim 1 wherein obtaining the profile of a combination of a full-frame camera and lens includes operating a full-frame camera and the lens to generate one or more point spread functions.

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 by retrieving a selected full-frame camera and lens profile from the plurality of electronic profiles and applying it to the image information to render the image with simulated optical characteristics of the full-frame camera;

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; and

quantizing the upscaled blur radius map to the closest indices in PSF information of the profile;

wherein the full-frame camera includes a color sensor that has a larger area than an area of the electronic sensor of the mobile electronic device.

13 . The system of claim 12 , wherein the mobile electronic device includes the electronic memory.

14 . The system of claim 12 , including a remote computer server including the electronic memory;

wherein the mobile electronic device is configured to communicate with the remote server wirelessly to access the plurality of electronic profiles.

15 . The system of claim 12 , wherein the profile includes point spread function information stored in the electronic memory as a one-dimensional array; and

applying the profile includes applying the point spread function information as a function of radial distance.

16 . The system of claim 12 , wherein the plurality of electronic profiles include a plurality of PSFs for a plurality of depths and focal distances for each combination of full-frame camera and lens.

17 . The system of claim 12 wherein each of the plurality of electronic profiles of combinations of full-frame cameras and lenses stored in an electronic memory is obtained by operating a full-frame camera and the lens to generate one or more point spread functions.
