Remote Controller Image Display Periodic Action for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling camera operations using a remote controller face challenges in reducing power consumption while maintaining user-friendly operations.
Innovation Solution
The system incorporates a communication unit, operation unit, display unit, and controller unit in the remote controller, which controls the reception and display of captured images based on the operation state of the remote controller during image capturing. It also interrupts communication paths when there is no user operation, switching between Wi-Fi and Bluetooth communication to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote controller continuously receives and displays captured images during image capturing, then the user can monitor the capturing process in real-time, but the power consumption increases significantly
Solution Approach 1:
The remote controller displays captured images periodically rather than continuously. The display unit shows images at predetermined intervals during image capturing, and the communication unit receives images at these periodic intervals. This periodic operation allows users to monitor the capturing process while significantly reducing power consumption compared to continuous display and reception.
2Speed
If the remote controller maintains continuous communication with the camera during image capturing, then real-time image transfer is enabled, but power consumption increases
Solution Approach 1:
The communication unit establishes a communication connection periodically during image capturing rather than maintaining continuous communication. Images are transferred at these periodic intervals when the display unit is updated. This approach enables real-time monitoring capability while reducing power consumption by keeping the communication unit inactive between periodic intervals.
3Loss of information
If the remote controller displays operation status information continuously, then the user has constant feedback about capturing state, but power consumption increases
Solution Approach 1:
The display unit displays operation status information periodically rather than continuously. The controller unit transmits operation status information to the remote controller at predetermined intervals, and the display unit updates the displayed status accordingly. This periodic information transmission and display provides users with feedback about the capturing state while significantly reducing power consumption compared to continuous information transmission and display.

AI summary
Reduction in power consumption of a video camera and a remote controller that displays a captured image of the video camera and improvement of operability are achieved. In a system including the video camera and the remote controller that displays a captured image of the video camera, when a period in which there is no operation on the operation unit of the remote controller reaches a first prescribed time, transmission of the captured image from the video camera to the remote controller via Wi-Fi communication and displaying processing on a display unit of the remote controller are stopped. Further, when a period in which there is no operation on the operation unit of the remote controller reaches a second prescribed time, the Wi-Fi communication is interrupted. Valid operation unit information in each mode is displayed on the display unit of the remote controller.
