Camera-Based Pointing Device Drift Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using an image capturing apparatus as a pointing device, sensor drift leads to a discrepancy between the position of the position display component and the attitude of the sender apparatus, compromising operability, especially when trying to interact with menu buttons on large display screens without a touch panel.
Innovation Solution
An image capturing apparatus with a storage unit, generating unit, output unit, attitude information acquiring unit, position display component managing unit, and operation accepting unit is implemented to generate and display an operation screen, convert attitude information into position information, and accept initialization operations to align the position display component with the sender apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image capturing apparatus is used as a pointing device to operate on a large display screen, then the ease of operation is improved, but the measurement precision deteriorates due to sensor drift causing discrepancy between position display component and apparatus attitude
Solution Approach 1:
The system continuously monitors the position of the position display component and the attitude of the image capturing apparatus, detects discrepancies caused by sensor drift, and provides feedback to correct the position display component's position to maintain alignment with the apparatus attitude
Solution Approach 2:
The patent replaces reliance on purely mechanical sensor-based position tracking with a software-based correction system that uses calculation and processing to determine and adjust the position display component's position, substituting physical sensor precision with computational accuracy
2Device complexity
If a separate pointing device is not provided and the image capturing apparatus is used as the pointing device, then the device complexity is reduced, but the reliability deteriorates due to operability compromise from position discrepancy
Solution Approach 1:
The image capturing apparatus is designed to serve multiple functions: capturing images and simultaneously functioning as a pointing device for operating the large display screen, eliminating the need for separate pointing devices while maintaining operational reliability through the position correction mechanism

AI summary
An image capturing apparatus is provided that is configured to generate an operation screen relating to an image stored in a storage unit, output the generated operation screen to a display apparatus, acquire attitude information relating to an attitude of the image capturing apparatus, converting the acquired attitude information into position information relating to a position of a position display component on the operation screen and display the position display component on the operation screen based on the converted position information, accept an initialization operation of initializing the position of the position display component, and display the position display component at an initial position of the operation screen in response to accepting the initialization operation.
