Person Detection Based Standby Control for Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face issues with interrupting processing or failing to transition to a standby state when a user leaves, leading to unintended processing interruptions or incomplete video playback due to the inability to prioritize transitions based on ongoing tasks.
Innovation Solution
An electronic apparatus with a system processing unit, person detection unit, operation control unit, and prohibition control unit that detects the presence or absence of a person to manage the operating state, limiting processing when a person is not present and allowing transitions back to normal operation upon their return, while ensuring video playback is properly resumed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the transition to standby state is forcibly made when the person leaves, then power consumption is reduced, but processing may be interrupted against the user's intention
Solution Approach 1:
The system dynamically adjusts the transition to standby state based on the execution state of processing. When processing is in a specific state (e.g., video playback), the transition is prohibited or delayed, allowing the system to adapt its power management behavior to current operational conditions rather than following a fixed rule
Solution Approach 2:
The system monitors the execution state of processing and uses this feedback to control whether transition to standby state is permitted. The prohibition control unit receives information about processing state and adjusts the standby transition accordingly, creating a closed-loop control system that prevents unintended interruptions
2Reliability
If the transition to standby state is prohibited when specific processing is executed, then processing continuity is maintained, but power consumption increases
Solution Approach 1:
The system dynamically determines whether to prohibit standby transition based on the specific processing state. Rather than always prohibiting standby when processing is active, the system selectively applies prohibition only when necessary (e.g., during video playback), allowing standby transition in other scenarios to conserve power
Solution Approach 2:
The prohibition on standby transition is applied selectively to specific types of processing rather than all processing uniformly. The system identifies particular processing states (e.g., video playback) that require continuous execution and applies prohibition only to those, while allowing other less critical processing to transition to standby
3Ease of operation
If the system transitions to standby state based on person detection, then ease of operation is improved, but processing state may cause incomplete video playback
Solution Approach 1:
The system uses feedback from the processing state (video playback status) to modify the automatic standby control behavior. When video playback is detected, the feedback mechanism prevents standby transition, ensuring complete playback while maintaining automatic control based on person detection
Solution Approach 2:
The prohibition control unit acts as an intermediary between the person detection unit and the standby control. It receives detection results and processing state information, then mediates whether standby transition should occur, balancing automatic control with video playback requirements

AI summary
An electronic apparatus includes: a system processing unit configured to execute system processing based on a system; a person detection unit configured to detect a change from a first detection state in which a person is present within a predetermined detection range to a second detection state in which no person is present; an operation control unit configured to instruct the system processing unit to cause the operating state of the system to make a transition to a first operating state when the change from the first detection state to the second detection state is detected by the person detection unit; and a prohibition control unit configured to instruct the operation control unit to prohibit the transition to the first operating state when the change from the first detection state to the second detection state is detected by the person detection unit.
