Motorized Camera Ejection for TV Power-On Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to use a TV camera, as they need to manually eject it, turn on the TV, and find the camera application, especially when the TV is powered off.
Innovation Solution
A display apparatus with a camera that can be moved up/down, featuring a detector to automatically turn on the TV and display a preview image when ejected, along with a controller that executes preset programs and lists camera-related applications, improving user convenience and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is made movable and ejectable from the display apparatus, then privacy protection is improved and camera functionality is enhanced, but device complexity and ease of operation deteriorate due to manual ejection requirements
Solution Approach 1:
The camera module automatically ejects and retracts without user intervention. The ejection is triggered automatically when the camera is needed (e.g., when a photo application is launched), and retraction occurs automatically after use, eliminating the need for manual operation while maintaining privacy protection through automatic repositioning.
Solution Approach 2:
The camera module is pre-configured to eject automatically before the user needs to use it. The system detects when a camera application is about to be used and initiates the ejection process in advance, so the camera is already in position when the user wants to take a photo, eliminating the need for manual ejection operations.
2Adaptability or versatility
If the camera is ejected from the display apparatus, then camera functionality is improved, but ease of operation worsens when the display apparatus is powered off
Solution Approach 1:
The camera module performs self-service by automatically ejecting when needed, even when the display apparatus is powered off. The system monitors for camera usage requests and autonomously handles the ejection and application launching process without requiring the device to be in a powered-on state, thereby maintaining ease of operation across all power states.
Solution Approach 2:
The system prepares the camera for use by automatically ejecting it and launching the appropriate application in advance, before the user actually needs to take a photo. This preliminary action sequence ensures that when the user wants to use the camera, everything is already ready, regardless of the device's power state.
3Ease of operation
If automatic ejection and power-on control are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller integrates multiple functions into a single control unit: it manages camera ejection, power supply control, and application launching. By making the controller universal and multi-functional, the patent reduces the need for separate dedicated components for each function, thereby managing device complexity while maintaining automatic operation capabilities.
Solution Approach 2:
The patent combines the control functions for camera ejection, power management, and application execution into a unified control process. The controller merges these previously separate operations into a single coordinated sequence, reducing system complexity by eliminating the need for independent control mechanisms for each function.

AI summary
Disclosed are a display apparatus and a control method thereof, the display apparatus including: a camera configured to include an image sensor for sensing an image passed through a lens, be mounted to movable up/down on a top of the display apparatus, and be moved up and ejected outward from the display apparatus while being used; an image processor configured to process an image signal corresponding to an image sensed by the image sensor; a display configured to display an image based on the processed image signal; a detector configured to detect whether the camera moves up or down; a power supply configured to supply power to elements of the display apparatus; and a controller configured to control the power supply to turn on the display apparatus if the detector detects that the camera is ejected while the display apparatus is being powered off, and control the image processor to display a preview image corresponding to an image taken by the camera on the display. Thus, the display apparatus can be easily turned on/off by pushing the camera, and be improved in utilization, thereby increasing accessibility to the utilization of the camera and improving convenience of a user.
