Solution Overview

Problem

Existing sports cameras face issues with poor image display due to device shaking and limited structural design, and there is a need for real-time image feedback and improved image processing during motion.

Innovation Solution

A control method and device that acquires real-time video frames, duplicates them for stability augmentation processing, and outputs one frame for display while saving the processed frame for storage, thereby reducing display delay and achieving high-quality image storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If stability augmentation processing is performed on real-time video frames, then image quality is improved, but processing time is increased

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent divides the single video frame processing into two separate frames: one dedicated to real-time display (unprocessed) and another to stability augmentation (processed). This segmentation allows simultaneous real-time feedback and high-quality stabilization without sequential processing delays.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a duplicate copy of the real-time video frame. One copy is used for immediate display without processing, while the other copy undergoes stability augmentation processing. This copying approach enables parallel processing paths that resolve the time-quality contradiction.

Inventive Principle:

Principle #26Copying

2Stability of the object's composition

If real-time video frames are processed for stabilization, then image stability is improved, but display delay is increased

Engineering Contradiction:

Improveimage stabilityVSAvoiddisplay delay

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system segments video frame handling into two distinct streams: one for real-time display and another for stabilization processing. This segmentation ensures that display delay is minimized for real-time feedback while stabilization processing occurs on a separate copy without affecting display timing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

By duplicating the video frame, the system can process one copy for stabilization while displaying the other in real-time. This copying mechanism allows image stability improvement without introducing display delay, as the processed and unprocessed frames are handled independently.

Inventive Principle:

Principle #26Copying

3Power

If computational processing is performed on video frames, then processing capability is improved, but energy consumption is increased

Engineering Contradiction:

Improveprocessing capabilityVSAvoidenergy consumption

Core Design Contradiction:

PowerVSUse of energy by moving object

Solution Approach 1:

The patent applies processing capability improvement partially - only to one of the two video frame copies. The other copy remains unprocessed and is used for real-time display. This partial action approach provides enhanced processing capability where needed while avoiding the full energy cost of processing all frames.

Inventive Principle:

Principle #16Partial or excessive action
