Frame Data HDR Transition Using Multi-Frame Display Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from Standard Dynamic Range (SDR) to High-Dynamic Range (HDR) display in video or image content results in visual effects that are not smooth, often causing jumps or flickers, affecting the user experience.
Innovation Solution
A method that involves obtaining HDR frame data from SDR frame data through dynamic range expansion, calculating differences in picture parameters, and performing multi-frame switching to gradually adjust these parameters, ensuring a smooth transition without flicker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If one-frame switching is used to transition from SDR to HDR display, then switching speed is improved, but visual smoothness deteriorates causing jumps or flickers
Solution Approach 1:
The patent segments the single-frame switching process into multiple sub-frames, where each sub-frame adjusts a portion of the picture parameters (such as brightness, contrast, or saturation) incrementally. This segmentation allows the transition to be divided into manageable steps, preventing abrupt visual changes while maintaining relatively fast switching speed.
2Stability of the object's composition
If multi-frame switching is used to transition from SDR to HDR display, then visual smoothness is improved, but switching speed deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of picture parameters across multiple frames, where the rate and magnitude of parameter changes are adaptively controlled based on the current frame's state and the target HDR state. This dynamic approach allows the system to prioritize visual smoothness during the transition while optimizing the overall switching duration.

AI summary
This application provides a frame data display method, an electronic device, and a storage medium. The method includes: obtaining HDR frame data of SDR frame data in response to an operation instruction generated by switching of a frame data display scenario; obtaining picture parameters of the SDR frame data and the HDR frame data; calculating a difference between the picture parameter of the SDR frame data and the picture parameter of the HDR frame data; determining a switching amplitude of an HDR display effect, a quantity of switching times, and a quantity of frames for each time of switching of the HDR display effect based on the difference; and performing multi-frame switching to display the SDR frame data as the HDR frame data through transition based on the switching amplitude of the HDR display effect, the quantity of switching times, and the quantity of frames for each time of switching of the HDR display effect. In this application, in a process of switching the frame data from SDR display to HDR display, the HDR display effect is divided into a plurality of frames for switching based on a variable of the picture parameter, so that the HDR display effect is smoothly transitioned, thereby avoiding jump or flicker in display of the HDR frame data, and improving user experience.
