Motion Blur Simulation via Frame Alignment and Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capturing panning images with motion blur requires precise control over camera movement and exposure time, making it difficult for photographers to achieve the desired effect without steady hands or specialized equipment.
Innovation Solution
A device and method that receive multiple frames, identify and track an object of interest, align the frames to simulate motion blur, and generate a final frame by blending the aligned frames, allowing for user-selectable motion blur simulation without the need for manual panning or long exposure times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a photographer uses manual panning technique to capture motion blur, then the object can be sharp while background is blurry, but it requires precise camera control and steady hands which increases operation difficulty
Solution Approach 1:
The patent replaces manual mechanical camera panning with an automated computational system. The processor automatically aligns multiple frames by detecting object position across frames and applying digital transformations, eliminating the need for manual camera tracking while achieving the same sharp object with blurred background effect
Solution Approach 2:
The patent creates multiple copies of the scene at different time points (multiple frames) and processes them computationally. By capturing several frames and digitally aligning them, the system reproduces the motion blur effect without requiring the photographer to manually track the moving object through panning
2Manufacturing precision
If a photographer reduces shutter speed to capture motion blur, then motion blur effect is achieved, but exposure time becomes difficult to determine and control
Solution Approach 1:
The patent performs preliminary actions by capturing multiple frames at standard shutter speeds before processing. Instead of attempting to determine the correct long exposure time, the system pre-captures several shorter exposure frames and combines them computationally to achieve the equivalent motion blur effect of a long exposure
3Manufacturing precision
If frame interpolation is used to generate additional frames, then the quality of motion blur simulation is improved, but the processing time and computational complexity increase
Solution Approach 1:
The patent applies partial action by offering users a choice of processing modes. Frame interpolation can be selectively applied to generate additional frames for higher quality motion blur, or users can process only the originally captured frames for faster results. This allows balancing quality requirements against time constraints
