Video Buffer Storage for Combined Drawing and Camera Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional approaches to generating and editing media content on computing devices are uninteresting, boring, and not sufficiently interactive, as they require separate storage and processing of videos and drawings, leading to inefficiencies when trying to render them together.
Innovation Solution
A system and method that initiates a video capture mode, detects touch gestures to render drawings overlaying the camera view, combines video image frames with drawings before buffer storage, and stores these combined frames in a video buffer to generate interactive video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If videos and drawings are stored separately in conventional approaches, then storage and processing can be done independently, but additional processing is required to render them together, reducing efficiency
Solution Approach 1:
The patent combines video frames and drawings into a single composite frame before buffer storage. The video rendering module renders video frames, the drawing rendering module renders drawings, and the frame combining module merges them into unified frames that are then stored in the video buffer. This eliminates the need for separate processing and rendering of video and drawing layers, improving rendering efficiency and reducing processing complexity.
Solution Approach 2:
The system performs preliminary combining of video and drawing frames before they are stored in the buffer. By pre-combining the frames during the recording phase rather than during playback or post-processing, the system avoids the need for complex real-time composition operations later, thereby improving overall productivity.
2Adaptability or versatility
If drawings are rendered to overlay camera view in real-time, then interactive media content is created, but additional rendering processing is required
Solution Approach 1:
The patent merges the video rendering function and drawing rendering function into a unified frame composition process. The frame combining module integrates rendered video frames with drawn drawings into single composite frames, allowing interactive content creation without requiring separate complex rendering pipelines for video and drawing overlays.
3Productivity
If video frames and drawings are combined before buffer storage, then rendering efficiency is improved, but frame composition processing is added
Solution Approach 1:
The frame composition operation is performed in advance during video recording, not during playback. The frame combining module combines video and drawing frames before they are stored in the video buffer, so that when the video is played back, the composition work is already complete. This preliminary action eliminates time loss during playback while maintaining rendering efficiency.

AI summary
Systems, methods, and non-transitory computer-readable media can initiate a video capture mode that provides a camera view. A touch gesture can be detected via a touch display. A drawing can be rendered based on the touch gesture. The drawing can be rendered to appear to overlay the camera view. A first video image frame can be acquired based on the camera view. At least a portion of the first video image frame and the drawing can be combined to produce a first combined frame. The drawing can appear to overlay the first video image frame. The first combined frame can be stored in a video buffer.
