Parallel Camera Reboot and Image Encoding for Mobile Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging devices on mobile terminals require sequential processing for photographing, which prolongs the time between consecutive photographing events due to sequential operations such as image acquisition, encoding, and camera re-booting.
Innovation Solution
Implementing a control unit that encodes images and re-boots the camera in parallel, allowing simultaneous encoding and re-booting operations to reduce the time between photographing events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sequential processing is used for image acquisition, encoding, and camera re-booting, then the processing order is simple and easy to control, but the time between consecutive photographing events is prolonged
Solution Approach 1:
The camera re-booting operation is initiated in advance before the image encoding is completed. The control unit starts the re-booting sequence after acquiring the image data, allowing the camera to be ready for the next photographing event without waiting for the encoding to finish, thus overlapping operations and reducing total time.
Solution Approach 2:
The system maintains continuous processing by initiating the camera re-booting operation while the image encoding is still in progress. This ensures that the camera is continuously transitioning between states without idle waiting time, and the next photographing event can be prepared for without interruption to the overall workflow.
2Productivity
If sequential processing is used for image acquisition, encoding, and camera re-booting, then the control logic is simple, but the productivity for consecutive imaging is reduced
Solution Approach 1:
The control unit initiates camera re-booting after image acquisition but before encoding completes. This preliminary action ensures the camera is ready for the next shot without delaying the encoding process, thereby increasing consecutive imaging productivity while maintaining relatively simple control logic through predetermined timing sequences.
3Duration of action of moving object
If the camera is re-booted after image encoding is completed, then the processing sequence is simple, but the total processing time is extended
Solution Approach 1:
The camera re-booting is triggered as a preliminary action after image acquisition, not after encoding completion. The control unit uses a timer or event-driven mechanism to start re-booting in the appropriate time window, allowing the camera to be ready before the next photographing event without extending the total processing duration.
