Adaptive Resolution Inclination Indicator for Camera Posture Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in accurately adjusting the posture of the camera to a horizontal state due to constant movement of inclination indicators, which can be visually annoying and degrade image quality, and require manual adjustments that are time-consuming and often unsatisfactory.
Innovation Solution
An imaging apparatus with an inclination detector, a display unit, and a selector unit that operates a first and second inclination indicator, allowing for adjustable resolution and notification methods based on the camera's state (held or fixed) to facilitate easier posture adjustment, using visual and auditory cues to indicate inclination levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a constant resolution inclination indicator is displayed to notify the user of the degree of inclination, then the user can see the inclination information, but the indicator constantly moves when the apparatus is hand-held making it difficult to know when horizontal and visually annoying
Solution Approach 1:
The patent applies dynamics by making the indicator resolution adaptive rather than fixed. The control unit dynamically adjusts the resolution of the inclination indicator based on the detected posture stability of the apparatus. When the apparatus is hand-held and unstable, the resolution is reduced to prevent constant movement and visual annoyance. When the apparatus is mounted on a tripod and stable, the resolution is increased to provide precise inclination information for accurate horizontal adjustment.
Solution Approach 2:
The patent changes the parameter of indicator resolution based on the operational state of the apparatus. The control unit monitors posture stability and adjusts the resolution parameter accordingly - using lower resolution for hand-held mode and higher resolution for tripod-mounted mode. This parameter adaptation resolves the contradiction between providing precise measurement and ensuring ease of operation.
2Measurement precision
If the inclination indicator is displayed with high resolution to show precise inclination information, then accurate adjustment can be achieved, but the indicator becomes visually annoying and degrades image quality when the apparatus is hand-held
Solution Approach 1:
The patent applies local quality by providing different indicator resolutions for different operational contexts. Instead of a uniform high-resolution indicator that causes visual annoyance during hand-held operation, the system provides locally adapted quality - lower resolution when hand-held and higher resolution when mounted. This resolves the contradiction between measurement precision and visual quality by making the indicator quality appropriate for each local operational condition.
Solution Approach 2:
The system dynamically adjusts the indicator resolution based on the detected operational state. The control unit monitors whether the apparatus is hand-held or mounted on a tripod and automatically adjusts the resolution parameter. This dynamic adaptation eliminates the harmful effect of constant indicator movement during hand-held operation while maintaining high precision when mounted, thus resolving the contradiction between accuracy and visual quality.
3Loss of information
If manual posture adjustment is required based on inclination notification, then the user can adjust the camera, but the process is time-consuming and often unsatisfactory due to resolution mismatch between indicator and manual adjustment capability
Solution Approach 1:
The patent changes the resolution parameter of the inclination indicator to match the operational context and user capability. When the apparatus is hand-held, the resolution is reduced to a level that matches manual adjustment capability, preventing information overload. When mounted on a tripod, the resolution is increased for precise adjustment. This parameter adaptation reduces adjustment time by providing appropriately scaled information for each operational mode.
Solution Approach 2:
The system provides feedback by monitoring the operational state (hand-held or mounted) and adjusting the indicator resolution accordingly. This feedback loop ensures that the inclination information displayed is always appropriate for the current operational context, helping users make efficient adjustments without wasting time on overly precise information that cannot be acted upon manually.
4Loss of information
If the assist line is displayed to indicate current posture, then the user can see the inclination direction, but the line constantly moves making it difficult to know when horizontal and can be a visual annoyance
Solution Approach 1:
The patent applies dynamics by making the assist line resolution adaptive. The control unit dynamically adjusts whether to display the assist line and at what resolution based on the detected posture stability. When the apparatus is hand-held, the assist line is either not displayed or displayed at lower resolution to prevent constant movement and visual annoyance. When mounted on a tripod, the assist line is displayed at high resolution to provide clear horizontal detection guidance.
Solution Approach 2:
The system changes the display parameter of the assist line based on operational state. The control unit monitors whether the apparatus is stable (mounted) or unstable (hand-held) and adjusts the assist line visibility and resolution accordingly. This parameter adaptation resolves the contradiction between providing clear posture information and enabling easy horizontal detection by matching the information display to the operational context.
