Camera Rotary Dial Feedback for Low-Light Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera designs with rotary dials face challenges in operability in low-light conditions, often complicating the internal structure and increasing costs, and can degrade intuitive operation due to display-based solutions that are not environment-specific.
Innovation Solution
A camera system with a rotary dial that includes a brightness detection unit, a display unit, and a display control unit to adaptively display settings or dial state images based on environmental brightness, ensuring operability in various lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the illumination lamp is built in the dial, then the dial can be illuminated in dark environments, but the internal structure of the dial becomes complicated and costs increase
Solution Approach 1:
The patent displays an image representing the dial state on the monitor instead of physically illuminating the dial itself. This virtual copy allows users to see dial information in dark environments without modifying the dial's internal structure or adding illumination lamps to the dial.
Solution Approach 2:
The monitor serves as an intermediary between the dial and the user's vision. Instead of directly illuminating the dial, the system uses the monitor to display dial information, mediating the information transfer and avoiding direct modification of the dial structure.
2Loss of information
If the image picture of the dial is displayed on the monitor in conjunction with dial lock release operation, then the dial state is visible, but the image picture is displayed even in environments where the dial plate can be visually recognized, deteriorating operability
Solution Approach 1:
The system dynamically adjusts the display behavior based on environmental conditions. The display control unit determines whether to show the dial image on the monitor based on whether the dial plate is visually recognizable, making the system adaptive to different lighting conditions rather than using a fixed display mode.
Solution Approach 2:
The system changes the display parameter (showing or not showing the dial image on monitor) based on the environmental brightness condition. When the dial plate is visually recognizable, the display parameter is set to not show the image; when not recognizable, the image is displayed.
3Loss of information
If the image picture of the dial is displayed on the monitor in conjunction with illumination button operation, then the dial state is visible, but the intuitive operational feeling is damaged
Solution Approach 1:
The system provides visual feedback on the monitor only when the dial plate is not visually recognizable. This conditional feedback mechanism ensures that users receive information when needed (in dark environments) while maintaining intuitive operation in bright environments where the dial is already visible.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operability by providing intuitive dial operation in both bright and dark environments without compromising usability, maintaining clear visibility and reducing structural complexity.

Data Source
AI summary
There is provided a camera of which operability is good regardless of the brightness of the surrounding environment. The brightness of the surrounding environment is detected by a brightness detection unit provided in a camera. The contents of settings of the camera are displayed on a sub-display 18 in a situation in which the surrounding environment is bright. The contents of settings of the camera and an image representing the set state of a shutter speed dial 33 are displayed on the sub-display 18 in a case in which the surrounding environment is dark.
