Solution Overview
Problem
Existing panning shot techniques struggle to ensure high accuracy in shake correction and improve shooting speed, as they rely on periodic acquisition and communication of panning shot information, which prolongs the time to shooting permission.
Innovation Solution
An imaging apparatus with a processor, acquisition unit for object motion vectors, detection unit for angular velocity, and calculation unit to determine panning shot assistance based on the reliability of angular velocity, allowing for accurate and efficient panning shot assistance by driving the shift lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If periodic acquisition and communication of panning shot information is performed, then shake correction accuracy is improved, but shooting speed deteriorates
Solution Approach 1:
The system performs preliminary acquisition of panning shot information (motion vectors, gyro data, vector detection) and calculates object angular velocity and acceleration in advance. This preliminary action allows the system to have correction information ready before shooting is triggered, enabling both high shake correction accuracy and fast shooting speed without requiring continuous periodic communication during the shooting moment.
2Reliability
If multiple acquisitions and communications of correction information are performed, then panning shot assistance accuracy is improved, but time to shooting permission increases
Solution Approach 1:
The system performs multiple acquisitions of panning shot information and calculates correction data in advance before shooting permission is needed. By completing these multiple acquisitions and calculations preliminarily, the system ensures high panning shot assistance accuracy while minimizing the time delay before shooting permission is granted.
3Measurement precision
If continuous monitoring of panning shot information is performed, then object angular velocity calculation accuracy is improved, but processing time increases
Solution Approach 1:
The system performs periodic acquisition of panning shot information (motion vectors, gyro information, vector detection information) at specific intervals rather than continuous monitoring. This periodic action allows sufficient time to calculate accurate object angular velocity and acceleration while controlling the total processing time within acceptable limits.
Data Source
AI summary
An imaging apparatus includes a CPU and an angular velocity sensor that detects an angular velocity of the imaging apparatus. The CPU acquires a motion vector of an object and calculates an angular velocity of the object based on the motion vector on the image plane of the object and the angular velocity of the imaging apparatus. Additionally, the CPU determines whether or not a panning shot is to be assisted depending on the reliability of the angular velocity of the imaging apparatus and the angular velocity of the object.
