Image Pickup Apparatus Subject Angle Tracking During Panning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pick-up apparatuses struggle to maintain a desired subject angle during panning photography, especially when the subject is moving at high speeds, leading to potential failure in minimizing subject shake and achieving the desired dynamic effect.
Innovation Solution
An image pick-up apparatus equipped with a first detection unit for panning state, a second detection unit for motion vectors, an acquisition unit for photographing distance, and a calculator to determine the angle between the apparatus and the subject, allowing for automatic photography when the calculated angle matches a predetermined setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If shutter speed is set slower to accomplish dynamic feeling, then dynamic effect is improved, but hand shake and subject shake are easily exhibited
Solution Approach 1:
The system uses angular velocity detection to provide feedback about camera motion, and motion vector detection to provide feedback about subject motion. This feedback enables real-time calculation of the subject angle and automatic adjustment of photographing timing to maintain the desired subject angle despite camera shake, allowing slower shutter speeds to be used without compromising image quality.
Solution Approach 2:
The patent replaces manual timing judgment and mechanical panning control with electronic detection systems (angular velocity sensor, motion vector detection) and automated control algorithms. This substitution enables precise measurement of camera and subject motion, allowing the system to automatically determine optimal photographing timing based on calculated subject angles.
2Measurement precision
If automatic photographing is implemented to capture desired subject angle, then photographing accuracy is improved, but device complexity increases
Solution Approach 1:
The camera system integrates multiple detection and processing functions into a unified control architecture. The angular velocity detection unit, motion vector detection unit, and subject angle calculation unit work together as an integrated system, with the photographing control unit coordinating all functions to achieve automatic timing based on subject angle, reducing overall system complexity through functional integration.
3Speed
If panning is performed to track moving subject, then subject tracking is improved, but maintaining desired subject angle becomes difficult when subject speed is high
Solution Approach 1:
The system dynamically adjusts the photographing timing based on real-time calculation of the subject angle, which changes as the subject moves. Rather than using fixed timing or manual adjustment, the system continuously updates the optimal photographing moment based on current camera angular velocity and subject motion vectors, enabling accurate angle maintenance even during high-speed panning.

AI summary
An image pick-up apparatus acquires a photographing distance and calculates angle information on the basis of a detection result of a motion vector in a panning state and a photographing distance. The image pick-up apparatus performs automatic photographing when the calculated angle information is a predetermined angle.
