Touchscreen Camera Control via Tap-to-Center and Dynamic Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing systems with a scroll bar for remote camera control narrow the viewable image range by occupying display space, limiting user visibility.
Innovation Solution
An electronic device with a touchscreen that receives camera image data via wireless communication, allowing users to tap and center the image on the screen, while displaying operation sliders to control the camera's direction, thereby preventing the narrowing of the display range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a scroll bar is displayed on the touchscreen to enable remote camera control, then the camera's remote controllability is improved, but the display range of the camera image becomes narrow due to the scroll bar overlapping the image
Solution Approach 1:
The patent applies the dynamics principle by making the operation interface appear only when needed (when the touchscreen is tapped) and disappear automatically after a predetermined time or when the camera reaches the target position. This dynamic display approach allows the full image area to be utilized during normal viewing while providing accessible control functionality when required, thus resolving the contradiction between ease of operation and display range.
2Ease of operation
If operation interfaces are continuously displayed on the touchscreen, then the ease of operating the camera is improved, but the visible area of the camera image is reduced
Solution Approach 1:
The patent implements periodic action by displaying the operation interface (sliders) only during specific periods - when the touchscreen is tapped - and hiding it during other periods. The interface reappears only after a predetermined time elapses or when camera movement is required, creating a periodic display pattern that maximizes image visibility while maintaining operational accessibility.

AI summary
An electronic device includes a receiver that receives image data of an image taken with a camera by wireless communication, a touchscreen that displays a camera image of the camera, and a controller that, when the touchscreen is tapped, gives the camera instructions on a capturing direction so that a tapped position of the image displayed on the touchscreen moves to the center of the touchscreen, and displays on the camera image an operation image for receiving an operation to instruct the capturing direction of the camera.
