Touch Screen Rotating Wheel for Camera Settings Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras lack intuitive controls for settings like ISO, focal length, and exposure, especially for users transitioning from film cameras, and often require physical knobs or complex menus, which can be daunting for both professionals and novices.
Innovation Solution
A touch screen interface that simulates a rotating wheel for selecting camera settings, displaying current and selectable values, with a preview image showing the effects of changes, allowing users to swipe or press arrows for adjustments, providing an intuitive and visual control method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical knobs or mechanical controls are used for camera settings, then ease of operation is improved for professional photographers, but device complexity increases and the interface becomes less intuitive for digital camera users
Solution Approach 1:
The patent replaces physical mechanical knobs with a virtual rotating wheel displayed on a touch screen. This substitution maintains the intuitive rotational interaction familiar to professional photographers while eliminating the need for additional physical components, thereby improving ease of operation without increasing device complexity.
Solution Approach 2:
The patent creates a visual copy of the traditional rotating wheel interface on the digital display. This virtual representation replicates the familiar mechanical control experience, allowing users to interact with camera settings through a simulated physical interface that is already well-understood by professional photographers.
2Adaptability or versatility
If multiple camera settings are made available, then adaptability is improved for professional photographers, but device complexity increases making the interface daunting for novice users
Solution Approach 1:
The patent segments the camera settings interface into distinct, independently controllable parameters (ISO, focal length, exposure time) that can be adjusted separately using the rotating wheel. This segmentation allows professional photographers to access and modify specific settings without being overwhelmed by the entire configuration space, reducing perceived complexity while maintaining adaptability.
Solution Approach 2:
The patent implements dynamic adjustment of camera settings through the rotating wheel interface, allowing users to smoothly transition between different parameter values. The interface dynamically updates the display to show the current setting and available options, making the complex range of camera parameters more manageable and intuitive for users of all skill levels.
3Ease of operation
If camera settings are displayed with visual feedback showing the effect of changes, then ease of operation is improved for novice users, but use of energy increases due to additional display processing
Solution Approach 1:
The patent implements partial visual feedback by displaying only the currently selected parameter and its immediate options in the rotating wheel interface, rather than showing all possible camera settings simultaneously. This selective display approach provides sufficient visual feedback for intuitive operation while minimizing the processing and display energy required.
Solution Approach 2:
The patent changes the display parameters to show only essential information (current setting value and available options) rather than comprehensive camera configuration data. This parameter optimization maintains ease of operation through clear visual feedback while reducing the energy consumption associated with displaying and processing extensive setting information.

AI summary
Various features for allowing a user to control a camera in an intuitive manner are described. Various features allow a user to control one or more camera settings via a touch screen. In some embodiments a rotating wheel is simulated on the display screen to show user selectable camera setting values with the values being displayed as if on the surface of the wheel with a currently selected value being closest to the user, e.g., in the center, and values above and below the currently selected value being shown using a smaller size as if further away from the user. A current setting for the feature being controlled is displayed near the center of the screen in some embodiments. A currently selected value is sometimes shown larger than other user selectable settings. The camera settings include an ISO setting, a focal length, e.g., zoom setting, and/or an exposure control setting.
