Unified Slider Control for Image Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capture devices provide complex and unintuitive control over exposure variables, requiring significant user knowledge and experience to achieve correct exposure and optimal image settings, with limited intuitive feedback on the effects of these variables on the captured image.
Innovation Solution
A method that determines and represents values of image variables such as aperture size, shutter speed, sensitivity, and scene luminance on a display using proportional display components, allowing users to adjust these values intuitively and maintain a pre-defined constant for optimal image luminance, enabling simplified control and feedback.

Engineering Contradiction Analysis
1Ease of operation
If conventional independent control of exposure variables (aperture, shutter speed, sensitivity) is provided, then full control over image capture parameters is achieved, but device complexity and difficulty of operation increase significantly
Solution Approach 1:
The patent combines multiple independent exposure controls (aperture, shutter speed, sensitivity) into a single unified slider control. This single control simultaneously adjusts all three parameters while maintaining their interrelationships, thereby simplifying the user interface and reducing operational complexity without sacrificing control capabilities.
Solution Approach 2:
The unified slider control serves multiple functions: it controls aperture size, shutter speed, and sensitivity simultaneously, and also provides visual feedback about the combined effect on image luminance. This multi-functional control element replaces what would traditionally require separate controls and feedback mechanisms for each parameter.
2Loss of information
If conventional independent display of variable values is provided, then complete information about each parameter is available, but intuitive understanding of combined effect on image luminance is lost
Solution Approach 1:
The patent implements a feedback mechanism where the unified slider control visually indicates the combined effect of aperture, shutter speed, and sensitivity settings on image luminance. As users adjust the slider, the system provides real-time visual feedback showing whether the combination will produce underexposed, correctly exposed, or overexposed images, making the complex interrelationships intuitive to understand.
Solution Approach 2:
The patent adds a new visual dimension to the control interface by displaying a graphical representation that shows the combined effect of all exposure parameters. This visual dimension complements the numerical values by providing an intuitive indicator of the overall exposure outcome, transforming abstract parameter relationships into perceptible visual information.
3Ease of operation
If semi-automated mode with automatic consequential changes is provided, then operation is simplified, but user understanding and control of individual variable effects are reduced
Solution Approach 1:
The unified slider control system automatically calculates and adjusts the appropriate combinations of aperture, shutter speed, and sensitivity based on user input, performing the complex computational work itself. The system serves the user by handling the mathematical relationships between parameters while still allowing the user to understand and control the overall effect through the visual feedback mechanism.

AI summary
There is provided a feedback and control method of operating a device. The method seeks to minimise cognitive load on a user, including novice users, and seeks to enable efficient, competent control of a device, and informed selection of and between optimum configurations. The method comprises determining values that are representative of each of a plurality of variables, representing each of the variables on a display using a display component, wherein a dimension of each display component is proportional to the value that is representative of the corresponding variable, and wherein the display components representing each of the variables are arranged substantially contiguously such that when the sum of the values is equal to a pre-defined constant (X) the substantially contiguously arranged display components extend between an origin point on the display and a target end point on the display, receiving an input that changes one of the values and consequentially adjusting the corresponding display component.
