10-bit Video Editing via Floating-Point Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most intelligent terminals do not support direct image operations on HDR videos, requiring conversion to low-quality SDR videos, which reduces user experience.
Innovation Solution
The electronic device implements a video editing method that allows outputting videos with a bit depth of 10 bits by splitting floating-point numbers into two floating-point numbers, enabling editing and saving of 10-bit videos without reducing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HDR video is converted to SDR video for image operation, then the video can be edited by existing processors, but the video quality is reduced
Solution Approach 1:
The patent segments a 10-bit color value into multiple 8-bit components through floating-point number splitting. Specifically, it converts a single floating-point number representing a 10-bit color value into multiple floating-point numbers that can be processed by existing 8-bit processors, then reconstructs the original 10-bit quality through weighted summation of these components.
2Ease of manufacture
If the image processor outputs 8-bit video frames, then the output function is compatible with existing systems, but the bit depth cannot reach 10 bits
Solution Approach 1:
The patent transforms a single 10-bit color value into multiple 8-bit color values by introducing a temporal dimension (multiple video frames). It splits one floating-point number into multiple floating-point numbers across different time points, processes them through existing 8-bit output functions, and reconstructs the 10-bit precision through temporal composition.
3Ease of operation
If HDR video is edited using existing output functions, then the processing is straightforward, but the edited video loses HDR quality
Solution Approach 1:
The patent introduces floating-point number splitting and temporal composition as intermediary processes between HDR video input and SDR processor output. It uses multiple video frames as intermediaries to carry the split color value components, enabling existing SDR processors to handle HDR content while preserving quality through the intermediary reconstruction process.

AI summary
Embodiments of this application provide a video editing method and an electronic device. When an image processor of the electronic device does not support to output a video with a bit depth of 10 bits by using an existing output function, an electronic device implementing the video editing method may edit the video with the bit depth of 10 bits based on an editing operation selected by a user, and output the video with the bit depth of 10 bits by using an existing function of outputting a video with a bit depth of 8 bits.
