FOV-UI for Remote Image Capture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems for image capture apparatuses struggle to intuitively display and adjust the field of view, making it difficult for users to perceive the relationship between pan, tilt, and zoom settings, and to determine the limits of adjustable ranges.
Innovation Solution
An electronic device with a field-of-view user interface (FOV-UI) that displays the current and maximum field of view of an image capture apparatus, allowing users to visually distinguish between the two and indicating limits through visual cues, enabling easier adjustment and prevention of exceeding adjustable ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate scroll bars and sliders are used to display pan, tilt, and zoom information, then the interface provides detailed control options, but the relationship between these parameters becomes hard to perceive
Solution Approach 1:
The patent combines separate scroll bars and sliders into a unified field-of-view indicator that displays pan, tilt, and zoom information together. This merging allows users to perceive the relationship between these parameters visually, as the indicator shows how changes in one parameter affect the overall field of view configuration.
Solution Approach 2:
The patent transforms one-dimensional scroll bar representations into a two-dimensional visual indicator that simultaneously represents multiple parameters. The field-of-view indicator uses spatial positioning and visual scaling to convey pan, tilt, and zoom relationships in a single graphical element, adding dimensional information that was previously distributed across separate controls.
2Device complexity
If only zoom magnification is displayed, then the interface remains simple, but the size of the field of view cannot be perceived
Solution Approach 1:
The patent uses visual scaling and graphical representation to convey field of view size. The field-of-view indicator dynamically adjusts its visual properties to reflect the current field of view dimensions, allowing users to intuitively grasp the size without adding complex interface elements.
3Device complexity
If traditional scroll bars are used, then the interface is simple to implement, but it is hard to perceive the limits of adjustable ranges
Solution Approach 1:
The field-of-view indicator provides continuous visual feedback about the current position relative to adjustable range limits. As users adjust parameters, the indicator updates to show proximity to maximum or minimum values, enabling users to understand the boundaries of the adjustable range without separate limit indicators.

AI summary
An electronic device displays an operation screen for remotely adjusting a field of view (FOV) of an external image capture apparatus. The operation screen comprises a field-of-view user interface (FOV-UI) that includes an indication of a current field of view of the image capture apparatus and an indication of a maximum field of view at a current orientation of the image capture apparatus. The electronic device updates the FOV-UI based on information acquired from the image capture apparatus.
