Multi-LUT Image Processing for Object-Specific Display Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices process images using a single Look Up Table (LUT), resulting in simple and uniform display effects, failing to meet the diverse shooting requirements of users when multiple objects are captured in a single image.
Innovation Solution
An electronic device recognizes different objects within an image and applies multiple LUTs to process each object separately, then composes the processed images to achieve varied display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single LUT is used to process the entire image, then the processing complexity is low, but the display effect diversity is insufficient
Solution Approach 1:
The image is segmented into multiple regions based on different shot objects (e.g., main subject, background, foreground). Each region is then processed by a separate LUT corresponding to its shooting scene, enabling different display effects for different parts of the image while maintaining manageable processing complexity through regional division.
Solution Approach 2:
Different LUTs are applied to different regions of the image based on the shooting scene of each shot object. This allows each region to have optimized local quality characteristics (e.g., portrait mode for faces, landscape mode for backgrounds) rather than applying a uniform processing approach to the entire image.
2Adaptability or versatility
If multiple LUTs are applied to different shot objects, then the display effect diversity is improved, but the calculation amount increases
Solution Approach 1:
The image is divided into regions corresponding to different shot objects, allowing selective application of multiple LUTs only to relevant regions rather than processing the entire high-resolution image with multiple LUTs, thus reducing overall calculation amount and power consumption.
Solution Approach 2:
Instead of applying multiple LUTs to the entire image, the system applies LUTs partially to specific regions containing shot objects. This partial action approach achieves the desired display effect diversity while significantly reducing the computational burden and energy consumption compared to full-image processing.
3Manufacturing precision
If the entire image is processed with high pixel density, then the image quality is high, but the calculation amount and power consumption increase
Solution Approach 1:
The image processing is segmented by region rather than uniformly applied across the entire high-resolution image. Only regions containing shot objects are processed with high-quality LUT application, while other regions use standard processing, thereby maintaining image quality where needed while reducing overall power consumption.
Solution Approach 2:
High-quality processing with multiple LUTs is applied locally to regions containing shot objects rather than uniformly across the entire image. This ensures high image quality for important elements while reducing the total calculation amount and power consumption by avoiding unnecessary processing in less critical regions.

AI summary
This application relates to the field of image processing, and provides an image processing method and an electronic device, to diversify a display effect of shooting or video recording. The method includes: The electronic device captures a first image. The first image is an image captured by a camera lens of the electronic device. The first image includes a first shot object and a second shot object. The electronic device determines a first scene corresponding to the first shot object and a second scene corresponding to the second shot object. The electronic device determines a first LUT based on the first scene, and determines a second LUT based on the second scene. The electronic device processes the first image based on the first LUT to obtain a second image, and processes the first image based on the second LUT to obtain a third image. A display effect of the second image is corresponding to the first LUT, and a display effect of the third image is corresponding to the second LUT. The electronic device displays a fourth image. The fourth image includes a part of the second image and a part of the third image. A display effect of the part of the second image is corresponding to the first LUT, and a display effect of the part of the third image is corresponding to the second LUT.
