Dynamic Image Resolution Processing for Video Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accidental activation of image acquisition devices during video connections can lead to privacy violations, as users may inadvertently share inappropriate or embarrassing environments with others.
Innovation Solution
A data processing method and device that acquire and process original images by adjusting their resolution parameters, such as sharpness and image area, to create processed images with distinct differences, which are then sent instead of the original images, thereby protecting user privacy by gradually changing the image clarity or area from blurred to clear, avoiding immediate exposure of the original environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the original image is transmitted immediately during video connection, then the image transmission speed is fast and the communication efficiency is high, but the user's privacy may be violated and inappropriate content may be exposed
Solution Approach 1:
The patent applies preliminary action by performing image processing (blurring, scaling, or cropping) on the original image before transmission. The processing circuit receives the original image from the image acquisition device and generates a processed image through operations such as blur processing, scaling processing, or cropping processing. This pre-processing ensures that even if transmitted immediately, the image content remains protected from privacy violations while maintaining efficient communication.
Solution Approach 2:
The patent introduces an intermediary processing circuit between the image acquisition device and the communication interface. This processing circuit acts as a mediator that transforms the original image into a processed image with altered resolution parameters (such as blur degree, scaling ratio, or cropping region) before transmission. The intermediary ensures that the transmitted image maintains communication functionality while preventing direct exposure of private or inappropriate content.
2Object-affected harmful factors
If image processing is performed on every frame to protect privacy, then privacy protection is improved, but the processing time increases and communication efficiency decreases
Solution Approach 1:
The patent applies partial action by selectively applying different processing degrees to different frames or regions of images. The processing circuit may apply stronger processing (higher blur degree, greater scaling, or more extensive cropping) to certain frames while applying lighter processing to others, based on the content importance or privacy sensitivity. This approach maintains adequate privacy protection while reducing overall processing time and computational load.
3Object-affected harmful factors
If the resolution parameter difference between processed and original images is large, then privacy protection is stronger, but the image quality degradation is more significant
Solution Approach 1:
The patent applies dynamics by making the resolution parameter difference dynamic rather than fixed. The processing circuit adjusts the processing degree (blur strength, scaling ratio, or cropping extent) based on real-time conditions such as the type of content being captured, the importance of the scene, or user preferences. This dynamic adjustment allows the system to maintain strong privacy protection when necessary while preserving image quality when appropriate, resolving the contradiction between protection level and quality.

AI summary
The present disclosure provides a data processing method. The data processing method includes acquiring a first original image and performing a first processing on the first original image to obtain a first processed image, a resolution parameter of the first processed image and the resolution parameter of the first original image having a first difference; and acquiring a second original image and performing a second processing on the second original image to obtain a second processed image. The resolution parameter of the second processed image and the resolution parameter of the second original image have a second difference. The second difference is different from the first difference. The first original image and the second original image are two frames in a plurality of consecutively acquired original images.
