Smartphone Camera Profile Simulation for Full-Frame Bokeh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphone cameras struggle to simulate the optical effects of full-frame cameras and lenses, such as bokeh, due to their smaller image sensors resulting in an almost infinite depth-of-field and lack of variation in blurring, which fails to replicate the aesthetic effects of full-frame camera systems.
Innovation Solution
A mobile electronic device is configured to generate a final digital image by applying profiles of full-frame camera and lens combinations to image information, using depth maps and point spread functions to simulate bokeh effects, including accurate depth information and chromatic aberrations, allowing for unique simulation profiles for each combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a full-frame camera and lens are incorporated into a smartphone, then the bokeh effect and optical characteristics are improved, but the device size and complexity increase making it infeasible for smartphone integration
Solution Approach 1:
The patent creates digital copies of full-frame camera and lens profiles, storing their optical characteristics (depth of field, bokeh, chromatic aberration) as data profiles. These profiles are applied to smartphone captured images through image processing algorithms, replicating the optical effects without physical full-frame hardware.
Solution Approach 2:
The patent replaces the mechanical/optical system of a physical full-frame camera with a computational system. Image processing algorithms substitute for optical physics, using software-based depth map analysis and profile application to simulate bokeh and other optical effects that would otherwise require specific physical camera hardware.
2Volume of moving object
If a smaller image sensor is used in a smartphone camera, then the device size is reduced, but the depth-of-field becomes almost infinite and bokeh effects are lost
Solution Approach 1:
The patent changes the parameters of the captured image through profile application. By applying stored full-frame camera profiles that contain depth-of-field and bokeh characteristics, the system transforms the optical parameters of the image post-capture, effectively overriding the physical constraints of the small sensor's infinite depth-of-field.
Solution Approach 2:
The patent performs preliminary action by pre-capturing depth information alongside the image data. This depth map is generated before the final image processing step, allowing the system to selectively apply blur and bokeh effects based on distance from the focal plane, thereby controlling depth-of-field effects in advance of the final image output.

AI summary
A method of generating an image may include 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/or generating, via an electronic control unit of the mobile electronic device, a final digital image via applying a profile of the one or more profiles to the image information.
