Camera Shutter Queue for Rapid Sequential Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle with slow shot-to-shot speed and difficulty in capturing images at desired timings due to ignoring subsequent user inputs during ongoing capturing operations.
Innovation Solution
Implementing a shutter queue mechanism in the electronic device to store subsequent user inputs and perform capturing operations only when the previous operation is completed and the time difference is within a threshold, ensuring immediate follow-up captures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the electronic device ignores subsequent user inputs during ongoing capturing operations, then the system stability is maintained, but the shot-to-shot speed decreases and images cannot be captured at desired timings
Solution Approach 1:
The system performs preliminary actions by storing subsequent user inputs in a queue during ongoing capturing operations. When a new user input is received, instead of ignoring it or causing system instability, the input is preliminarily queued and processed after the current operation completes, enabling rapid sequential captures without missing desired timing points
Solution Approach 2:
A queue mechanism is introduced as an intermediary between user input reception and capturing operation execution. This intermediary structure allows the system to buffer multiple user inputs and process them sequentially after ongoing operations complete, resolving the conflict between responsiveness and system stability
2Loss of time
If the electronic device waits for previous capturing operation to complete before processing new user input, then system stability is maintained, but time is lost and desired scenes may be missed
Solution Approach 1:
User inputs are preliminarily stored in the queue during ongoing operations rather than being processed immediately or ignored. This preliminary storage eliminates perceived delays while ensuring captures occur at the correct timing points when previous operations complete, preventing missed scenes
Solution Approach 2:
The queue mechanism enables continuous processing of user inputs without interruption. While one capturing operation is executing, subsequent user inputs continue to be received and queued, maintaining continuous readiness to capture without idle waiting time between operations

AI summary
An electronic device includes: a camera; memory comprising a storage space; and at least one processor operatively connected to the camera and the memory, wherein the at least one processor is configured to: based on receiving a first user input for capturing a first image, perform, using the camera, a first capturing operation; based on receiving a second user input for capturing a second image while the first capturing operation corresponding to the first user input is performed using the camera, store information regarding the second user input in the storage space; based on identifying a completion of the first capturing operation, identify whether a time difference between the second user input and the completion of the first capturing operation is less than or equal to a threshold; and based on identifying the time difference is less than or equal to the threshold, perform, using the camera, a second capturing operation corresponding to the second user input.
