Solution Overview

Problem

Existing electronic devices lack the ability to present a visual grain effect on images captured during video recording, limiting the richness and interest of the visual experience.

Innovation Solution

The electronic device processes images in real-time using selected film materials to apply corresponding film display effects, such as grain, scratch, and light leak effects, by distinguishing between skin and non-skin areas in portraits and applying different film materials to each, and using LUTs to adjust RGB values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If deep learning-based image processing is used to improve skin effect, then image quality is improved, but processing time increases and real-time processing becomes difficult

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent segments the image processing task into multiple processing stages (e.g., edge detection, skin tone adjustment, detail enhancement) that can be executed sequentially or in parallel. This allows the system to apply complex deep learning operations only to specific regions or aspects of the image rather than processing the entire image with full deep learning complexity, thereby reducing overall processing time while maintaining image quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs preliminary actions by pre-processing images to extract key features (such as skin regions, edges, and important structures) before applying deep learning-based enhancement. This pre-extraction of relevant information reduces the computational burden during the actual enhancement phase, enabling faster processing while preserving the ability to achieve high-quality results.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If complex image processing operations are applied to all images, then image quality is improved, but power consumption increases

Engineering Contradiction:
Improveimage qualityVSAvoidpower consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by differentiating processing strategies based on image characteristics. Complex deep learning-based operations are applied selectively to specific regions (such as skin areas or regions with important details) rather than uniformly to the entire image. This localized approach maintains high quality where needed while significantly reducing overall power consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements partial action by applying full deep learning processing only to a subset of images or specific regions within images, rather than applying exhaustive processing to all images. This selective application of processing power reduces energy consumption while maintaining acceptable quality levels across the overall output.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If real-time processing is prioritized with simpler algorithms, then processing speed is improved, but image quality deteriorates

Engineering Contradiction:
Improveprocessing speedVSAvoidimage quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent employs dynamics by making the processing algorithm adaptive and flexible. The system can dynamically adjust the level of processing complexity based on real-time conditions such as available computational resources, time constraints, and image characteristics. This allows the system to switch between simpler fast-processing modes and more complex high-quality modes, optimizing the balance between speed and quality for each specific situation.

Inventive Principle:
Principle #15Dynamics

AI summary

This application discloses an image processing method and an electronic device, and relates to the field of terminals. The method includes: An electronic device may obtain one or more film materials, where the one or more film materials include a first film material. When the electronic device receives and responds to a camera activated operation, the electronic device 100 may capture an image in real time through a camera. When the electronic device 100 receives and responds to a selection operation for the first film material, the electronic device 100 may process the image captured in real time based on the first film material, so that a first film display effect is presented on an image processed by the first film material. The first film display effect may include a grain effect, and/or a scratch effect, and/or a light leak effect.
