Camera Booting and Image Capture Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras require a significant standby time to boot up, making it difficult to capture fleeting moments, such as moving objects or quick events, when the camera is turned off.
Innovation Solution
A photographing control method and apparatus that simultaneously perform booting and capturing by using a power supply button in combination with a certain key button, allowing the camera to be turned on and ready for image capture without pressing the power supply button, and enabling booting and capturing when the certain key button is pressed for a predetermined time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the camera is turned off and then powered on to capture an image, then the camera can be used after booting is completed, but the standby time increases making it difficult to capture fleeting moments
Solution Approach 1:
The camera performs preliminary actions by pre-loading image data during the booting process itself. When the power button is pressed, the camera immediately starts capturing images using data that is being prepared in advance during system initialization, rather than waiting for complete booting before capturing any images.
Solution Approach 2:
The booting process and image capturing process are made continuous and overlapping rather than sequential. The camera continues the useful action of image capturing throughout the booting process, eliminating the idle waiting period between power-on and first capture.
2Speed
If the camera boots up completely before capturing an image, then the system is fully initialized, but the capture speed is too slow for fast-moving subjects
Solution Approach 1:
Image data is prepared and loaded into the buffer memory during the booting process itself, before the capturing command is fully executed. This preliminary preparation of image data during system initialization enables immediate high-speed capture when the power button is pressed.
Solution Approach 2:
The system dynamically adjusts the capturing process to occur during the booting sequence. The camera transitions from a static state of waiting for boot completion to a dynamic state where capturing occurs concurrently with system initialization, optimizing both speed and timing.
3Reliability
If the camera waits for booting completion before capturing, then all system functions are available, but the moment to be captured may be missed
Solution Approach 1:
The camera performs preliminary image data acquisition and buffering during the booting process. By the time the capturing command is fully executed, the image data is already prepared in the buffer, enabling immediate capture without waiting for complete system initialization.
Solution Approach 2:
The useful action of image capturing continues uninterrupted throughout the booting process. Instead of pausing for system initialization, the camera maintains continuous capturing operation, ensuring no moment is lost while the system becomes fully operational.

AI summary
Provided are a photographing control method and apparatus for capturing image data at a moment in time when booting. According to the photographing control method, booting and photographing are simultaneously performed by combining use of a power supply button and a certain key button or by pressing a certain key button for a predetermined time without pressing a power supply button.
