Camera Activation via Sensor-Powered Pre-Initialization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capturing devices face challenges in rapidly activating from a standby state without excessive power consumption, leading to missed shutter opportunities due to long initialization times and conflicting demands for quick activation and power efficiency.
Innovation Solution
The implementation of an image capturing device configuration that uses electrostatic or angular velocity sensors to detect the image capturing mode and initiate power supply and system initialization as background processing, allowing for instant activation when the mode is set, while minimizing power consumption in standby states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the system continuously supplies power to reduce activation time, then the activation time is reduced, but power consumption increases significantly
Solution Approach 1:
The system performs preliminary actions by detecting when the user picks up the camera and pre-initializing the system before the power switch is pressed. This includes pre-loading necessary data and preparing the image capturing components, so that when power is supplied, the activation is already nearly complete, significantly reducing the perceived activation time without requiring continuous power supply.
Solution Approach 2:
The system dynamically adjusts its power consumption state based on user behavior. It transitions from a low-power standby state to a high-performance active state only when needed, using sensor detection to trigger intermediate preparation states that optimize the balance between activation speed and power consumption.
2Reliability
If the system performs complete initialization after power supply, then system reliability is ensured, but activation time increases
Solution Approach 1:
The system performs preliminary initialization actions before the power switch is pressed by detecting user pickup. Necessary data is pre-loaded into memory, and system components are pre-configured, so that when power is supplied, the initialization process is already partially complete, ensuring reliability while reducing activation time.
Solution Approach 2:
The system performs partial initialization in advance based on predicted user needs. Not all system components are fully initialized before power supply, but only those necessary for immediate operation, allowing the system to achieve sufficient reliability for the current context without the full overhead of complete initialization.
3Use of energy by moving object
If the device remains in suspend state to save power, then power consumption is reduced, but activation time increases
Solution Approach 1:
When the user picks up the camera, the system detects this action and performs preliminary actions to exit suspend state and begin initialization processes before the power switch is pressed. This intermediate preparation reduces the activation time from suspend state without requiring the device to remain in a high-power state continuously.
4Reliability
If the chattering preventing process is performed sequentially before system initialization, then false operations are prevented, but activation time increases
Solution Approach 1:
The chattering preventing process is performed as a preliminary action immediately when the power switch is pressed, before system initialization begins. This ensures that false operations are prevented and the switch state is reliably determined, allowing system initialization to start without delay once the switch state is confirmed.

AI summary
An image capturing device includes a first controller for performing image capturing control, an operation section including a switch, a detecting section for detecting a change to an image capturing mode and sending a signal representing the change, a second controller for monitoring and processing the sent signal, the second controller having power consumption less than that of the first controller, and a power supply for supplying power to the first controller, the second controller, and a functional section included in the device. When the second controller receives the signal sent from the detecting section in a power saving state in which power is supplied from the power supply to the second controller, the power saving state is changed to a power supplying state capable of image capturing by supplying power from the power supply to portions of the device including the first controller.
