Display Sub-Frame Ordering to Reduce Camera Capture Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artifacts appear in captured images due to asynchronous exposure times of image capture devices and display times, causing flickering as the artifacts do not align consistently.
Innovation Solution
A light emission control method that divides light emitting elements into display sets and generates multiple sub-frames, determining a unique display order for each set to align sub-frames with display time intervals, ensuring consistent light emission across different display sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the display continuously shows the same image frame, then the display stability is improved, but artifacts appear in captured images due to asynchronous exposure times
Solution Approach 1:
The patent divides the display time period into multiple display time intervals and divides the image frame into multiple sub-frames. Each display set displays different sub-frames in different display time intervals, segmenting the display content to avoid consistent patterns that cause artifacts during capture exposure.
Solution Approach 2:
The patent implements periodic switching of display orders for different display sets. Each display set cycles through different sub-frame sequences in a periodic manner, creating time-varying display patterns that reduce artifact visibility in captured images.
2Device complexity
If different display sets use the same display order, then the device complexity is reduced, but flickering occurs in captured images
Solution Approach 1:
The patent assigns different display orders to different display sets, where each display set has its own unique mapping between sub-frames and display time intervals. This local differentiation in display control eliminates flickering artifacts while maintaining manageable system complexity through structured organization.

AI summary
A light emission control method includes: (A) generating multiple sub-frames based on an image frame that corresponds to a display time period including multiple display time intervals; (B) determining a display order of the sub-frames in the display time intervals, where the display order indicates, with respect to each of multiple display sets of a display, a one-to-one corresponding relationship between the sub-frames and the display time intervals, the one-to-one corresponding relationships with respect to the display sets are different from each other, and in the one-to-one corresponding relationships with respect to at least two of the display sets, a first one of the sub-frames corresponds to different ones of the display time intervals; and (C) in each of the display time intervals, controlling each of the display sets to display one of the sub-frames that corresponds to the display time interval based on the display order.
