Image Capture Zoom Feedback via Estimated Value Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to intuitively grasp the degree of zoom-out processing in area zoom functions, especially when the zoom state is near the wide-angle end, as the operation's effect is not clearly communicated, making it hard to understand how the zoom function operates.
Innovation Solution
The implementation of an image capturing control apparatus that displays an estimated zoom value icon and a zoom value display region on a slider, allowing users to visually understand the zoom change by showing the current and estimated zoom values, and altering the frame's display form when zoom limits are reached, such as changing its color or style to indicate impossibility of further zooming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If area zoom function is implemented without visual feedback, then the system remains simple, but users cannot intuitively grasp the degree of zoom-out processing
Solution Approach 1:
The patent implements visual feedback by displaying a frame indicating the designated area and icons showing current and estimated zoom values. This feedback mechanism allows users to intuitively grasp the degree of zoom-out processing and understand how the zoom function operates, resolving the information loss problem without excessive complexity
Solution Approach 2:
The patent uses color changes in the displayed frame and icons to communicate zoom state information. By altering the visual appearance based on zoom parameters, the system provides intuitive feedback about the zoom degree and operational status
2Loss of information
If zoom-out processing is performed near wide-angle end, then the camera reaches its zoom limit, but users cannot understand that further zoom-out is impossible
Solution Approach 1:
The patent provides continuous visual feedback through the displayed frame and zoom value icons that show the relationship between current and estimated zoom values. When the zoom limit is reached, this feedback mechanism communicates the impossibility of further zoom-out processing, improving user understanding
Solution Approach 2:
Instead of showing only the current zoom state, the patent displays both current and estimated zoom values, allowing users to understand the zoom limit by comparing what is currently achievable versus what was requested. This inverted approach of showing both states provides clarity about limitations
3Loss of information
If no visual indication of zoom values is provided, then the display system remains simple, but users cannot grasp the zoom action and its limits
Solution Approach 1:
The patent implements feedback by displaying icons that show both current zoom values and estimated zoom values. This visual feedback system provides comprehensive zoom state information including limits, while maintaining a relatively simple display interface through the use of intuitive icons and frames
Solution Approach 2:
The patent adds a visual dimension to zoom control by displaying graphical representations of zoom values and designated areas. This transforms the abstract zoom parameter into a visual format that users can intuitively grasp, adding information without requiring complex interface elements

AI summary
An image capturing control apparatus controls, in accordance with an end of an operation by a user on an image captured by an image capture apparatus, a parameter value according to the operation to be set in the image capture apparatus, and causes a display unit to display a display image which indicates the parameter value according to the operation and is different from the captured image. At a first time point in the middle of the operation by the user and before the parameter value according to the operation is set in the image capture apparatus, the display unit is caused to display the display image corresponding to the parameter value according to the operation at the first time point.
