Photographing Device Delay Time Calculation Using Pre-Captured Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographing devices experience delays between the user's intention to capture an image and the actual capture, especially with dynamic objects, leading to missed shots due to the inability to determine a standard delay time applicable to all users and devices.
Innovation Solution
A method and apparatus that calculate an average delay time by repeatedly capturing images and determining the difference between the initiation and imaging moments, allowing the device to automatically adjust and improve the timing for capturing desired photos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the photographing device captures images continuously at a preset imaging cycle, then the timing precision for capturing the desired moment is improved, but the device complexity increases due to the need to store multiple imaged photos and calculate delay times
Solution Approach 1:
The system performs preliminary actions by continuously capturing images at a preset imaging cycle before the actual photographing is initiated. Multiple imaged photos are stored in advance with their corresponding imaging moments recorded, so when photographing is triggered, the system already has a sequence of pre-captured images to choose from, improving timing precision without requiring complex real-time processing
Solution Approach 2:
The system implements feedback by calculating the delay time based on the difference between the initiation moment of photographing and the imaging moments of pre-captured photos. The average delay time is computed from multiple measurements and used to automatically determine the target imaged photo, creating a closed-loop feedback mechanism that improves timing accuracy
2Reliability
If the system calculates and determines a standard delay time through multiple photographing operations, then the photographing quality is improved by capturing images closer to the user's intention, but the time required for setup and calibration increases
Solution Approach 1:
The system performs self-service by automatically determining its own standard delay time through multiple photographing operations. The device autonomously calculates the average delay time from the difference between initiation moments and imaging moments, and uses this calculated value to automatically select the target imaged photo, eliminating the need for manual calibration and reducing setup time
Solution Approach 2:
The system performs preliminary calibration actions by executing multiple photographing operations to establish the standard delay time before normal operation. This preliminary phase captures the user's typical reaction time and device processing characteristics, enabling accurate timing in subsequent photographing operations
3Ease of operation
If the photographing device waits for user input to determine the target image, then the ease of operation is improved, but the loss of time increases due to the delay between user intention and actual capture
Solution Approach 1:
The system uses feedback by calculating the delay time from user input (the difference between when the user initiated photographing and when images were actually captured) and automatically using this information to determine the target imaged photo. This feedback loop eliminates the need for manual delay adjustment while capturing the user's intended moment, reducing photographing delay time while maintaining ease of operation
Solution Approach 2:
The device performs self-service by automatically determining the target imaged photo based on the calculated average delay time, without requiring the user to manually select or adjust timing parameters. The system autonomously processes the user's photographing initiation and selects the appropriate pre-captured image, reducing the time loss between user intention and actual capture

AI summary
A method and an apparatus for determining a photographing delay time and a photographing device are disclosed. The method includes: controlling the photographing device to form, according to a preset imaging cycle, an image of a photographed object, and storing an imaged photo; each time photographing is initiated, displaying the imaged photo and receiving a first operation instruction entered by a user; determining, according to the first operation instruction, a corresponding target imaged photo; calculating a difference between an initiation moment of each time of photographing and an imaging moment of the corresponding target imaged photo, to obtain a delay time corresponding to a single time of photographing; and calculating an average value of delay times corresponding to at least two times of photographing, where the average value may be used as a standard delay time caused by an operation of the user on the photographing device.
