Object Detection Unit Power Switching for Faster Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information processing methods in electronic devices require time to wake up image acquisition apparatuses, extending processing time and reducing device start efficiency.
Innovation Solution
An information processing method involving an object detection unit that sends a status switch instruction to a control unit, causing the electronic device to switch from a low power status to a high power status for rapid object recognition, thereby shortening processing time and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the image acquisition apparatus is kept in a low power status to save energy, then power consumption is reduced, but the device start efficiency deteriorates due to the time needed for waking the apparatus
Solution Approach 1:
The object detection unit is activated in advance and performs detection operations before the main image acquisition apparatus needs to be fully operational. This preliminary detection allows the system to prepare and reduce the time required for the apparatus to transition from low power status to full operation, thereby resolving the contradiction between energy saving and start efficiency.
2Loss of time
If the object detection unit switches to high power status immediately upon detection to improve recognition speed, then processing time is reduced, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the power status of the object detection unit based on detection needs. The unit switches between first status (lower power) and second status (higher power) only when necessary for detection operations, rather than maintaining a fixed high power state. This dynamic adjustment reduces overall power consumption while maintaining fast processing capability when needed.
3Speed
If the electronic device maintains all components in high power status to ensure rapid response, then response speed is improved, but overall power consumption increases
Solution Approach 1:
The system segments the detection functionality into a separate object detection unit that can operate independently in different power statuses. This allows the main image acquisition apparatus to remain in low power status while the detection unit handles preliminary detection tasks, achieving fast response for detection events without requiring the entire system to consume high power continuously.

AI summary
An information processing method, applied to an electronic device including an object detection unit and a control unit, comprising determining that a target object is detected. The object detection unit sends a status switch instruction to the control unit and controls the object detection unit to switch from a first status to a second status, and the status switch instruction is used to cause the electronic device to switch from a third status to a fourth status. The method further includes determining that the object detection unit enters the second status. In response to a control instruction sent by the control unit, the object detection unit obtains an object feature of the target object to cause the electronic device to perform recognition on the target object based on the object feature.
