Scenario-Based Camera Wake-Up for Faster Module Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems require lengthy activation times due to the activation of multiple functional modules, leading to increased user waiting times, especially in scenarios where rapid response is needed.
Innovation Solution
A method and apparatus for a camera that acquires wake-up signals, processes them to identify indicative features, determines wake-up scenarios, and activates functional modules based on predefined activation schemes prioritizing those relevant to the scenario, thereby optimizing the camera's wake-up process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all functional modules are activated to support multiple camera functions, then the camera's functionality and versatility are improved, but the total activation time increases leading to longer user waiting time
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple activation schemes that correspond to different wake-up scenarios. When a wake-up signal is received, the system quickly identifies the scenario type and retrieves the corresponding pre-configured activation scheme, avoiding the need to determine module priorities in real-time. This pre-preparation significantly reduces the activation time while maintaining the ability to support multiple camera functions through scenario-specific optimized module configurations.
2Use of energy by moving object
If the camera remains in a dormant state to save power, then energy consumption is reduced, but the response time when waking up increases
Solution Approach 1:
The patent applies segmentation by dividing the camera system into different functional modules that can be independently activated based on the wake-up scenario. Instead of activating all modules simultaneously or keeping the entire system fully powered, the system selectively activates only the necessary modules for the current scenario. This granular control allows the camera to remain in a low-power dormant state while enabling fast wake-up by activating only essential modules based on pre-defined schemes.
3Adaptability or versatility
If multiple functional modules are activated simultaneously, then all camera functions are available, but the activation complexity and coordination overhead increase
Solution Approach 1:
The patent resolves activation complexity by pre-defining multiple activation schemes that map to different wake-up scenarios. Each scheme contains pre-determined module priority configurations optimized for specific scenarios. When a wake-up signal is received, the system simply identifies the scenario type and applies the corresponding pre-configured scheme, eliminating the need for complex real-time decision-making and module coordination logic.

AI summary
The present disclosure provides a method for waking up a camera and apparatus thereof. The method includes: acquiring at least one wake-up signal for waking up the camera; performing pre-determined signal processing on the acquired wake-up signal to extract indicative features; determining wake-up scenario information corresponding to the acquired wake-up signal based on the indicative features; determining, based on the determined wake-up scenario information, an activation scheme corresponding to the wake-up scenario information, wherein the activation scheme defines activation priority at least one functional module in the camera in the wake-up scenario; and activating at least one functional module based on activation priority defined in the determined activation scheme.
