Camera Rear Command Dial Adaptive Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera configurations suffer from poor operability due to the separation of the image picture of the operation dial from the display section, leading to increased eye movement and confusion in operation, as well as a weak connection between the operation dial and display section.
Innovation Solution
A camera design incorporating a rotary operation dial near the display section, a detection unit for finger contact or approach, and a display control unit that displays setting contents on the display section, with the image picture of the operation dial appearing in different sizes based on user interaction, such as touch, continuous contact, or operation, and using a lock unit to manage display formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the image picture of the operation dial is displayed on a separate display section, then the setting contents can be displayed, but the line of sight movement increases and operability deteriorates
Solution Approach 1:
The patent merges the display section with the operation dial by integrating the display function directly into the operation dial structure. The display section is positioned such that the image picture of the operation dial and the setting contents are shown in close proximity or overlapping arrangement, allowing users to view both the dial position and setting information without significant eye movement, thereby improving operability while maintaining information display capability.
2Loss of information
If the image picture of the operation dial is displayed on a separate display section, then the setting contents can be displayed, but the connection between the operation dial and display section becomes weak and operation becomes confusing
Solution Approach 1:
The display section is integrated with the operation dial structure, creating a unified visual element where the image picture of the operation dial and the setting contents are displayed together. This merging strengthens the connection between the physical operation dial and its visual representation, making the operational relationship clear and intuitive without adding complex separate display mechanisms.
Solution Approach 2:
The patent uses an image picture (visual copy) of the operation dial displayed on the display section that accurately represents the physical dial's position and state. This visual copy maintains a strong correspondence with the actual operation dial, allowing users to understand the setting state clearly without confusion, while the display section remains integrated rather than completely separate.
3Area of stationary object
If the image picture of the operation dial is displayed in a small size, then the display section space is utilized, but the visibility and user awareness of the operation state is reduced
Solution Approach 1:
The patent employs dynamic display characteristics where the image picture of the operation dial can change its display characteristics (such as size, brightness, or emphasis) based on operational state. When the operation dial is being operated or when contact is detected, the display can enhance the visibility of the image picture, making it appear larger or more prominent temporarily, while maintaining space efficiency during normal states.
Solution Approach 2:
The patent utilizes visual property changes (such as brightness, color intensity, or contrast adjustments) of the displayed image picture to enhance visibility without increasing physical display area. By making the image picture of the operation dial visually distinctive through color or brightness changes, especially during operation, the system maintains high visibility within the constrained display space.

AI summary
Provided are a camera with good operability and a display control method of the camera. Contact of a finger with a rear command dial D1 is detected. In a case where the contact of the finger with the rear command dial D1 is not detected, only setting contents of the camera are displayed on a sub-display 16 provided near the rear command dial D1. In a case where the contact of the finger with the rear command dial D1 is detected, an image picture of the rear command dial D1 is displayed in a first size on the sub-display 16. In a case where the contact of the finger with the rear command dial D1 is continuously detected for a certain period of time or more, or in a case where the rear command dial D1 is operated, the image picture of the rear command dial D1 is enlarged and displayed in a second size.
