Imaging Device Processor Buffering for Parameter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices struggle to easily capture moving images under desired user-imposed imaging conditions, particularly when switching parameters like white balance or exposure.
Innovation Solution
An imaging device with a processor that sets and manages two different imaging parameters (first and second parameters) for moving image data, allowing for seamless switching and reflection of changes only in the live view image, ensuring accurate capture of desired imaging conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging parameters are changed during moving image capture, then the imaging conditions can be adjusted to match user desires, but the already-captured images with inappropriate parameters are wasted
Solution Approach 1:
The system performs preliminary buffering of captured moving image data in memory before final recording. When parameter changes are made, the buffered data can be reprocessed with new parameters before being recorded, preventing waste of imaging data while enabling flexible parameter adjustment.
2Reliability
If parameter changes are immediately reflected in recorded moving image data, then the recorded data matches current imaging conditions, but changes made during capture cannot correct previously captured data
Solution Approach 1:
The system buffers incoming moving image data in memory before recording, allowing parameter changes to be applied to the buffered data. This ensures that recorded data always reflects the most recent imaging conditions while maintaining the ability to adjust parameters during capture.
Solution Approach 2:
The buffer memory acts as an intermediary between the imaging unit and the recording destination. It temporarily holds moving image data, allowing parameter changes to be processed on the buffered data before recording, thus mediating between immediate recording and parameter adjustment flexibility.
3Productivity
If parameter changes are applied to already-saved moving image data in memory, then data efficiency is improved, but the system complexity increases
Solution Approach 1:
The buffer serves as an intermediary storage layer that enables efficient data utilization. By holding data temporarily in memory, the system can reprocess buffered frames with new parameters without requiring complex real-time processing or additional hardware components.

AI summary
Provided are an imaging device, an imaging method, and an imaging program capable of easily capturing a moving image under an imaging condition desired by a user. In one aspect of the present invention, an imaging device includes an imaging unit and a processor. The processor sets a first imaging parameter applied to moving image data captured by the imaging unit, records first moving image data captured based on the first imaging parameter on a recording device before a first operation by a user of the imaging device is received, sets a second imaging parameter applied to the moving image data in a case where the first operation is received, and records the second moving image data captured based on the second imaging parameter on the recording device in a case where a second operation by the user is received after the reception of the first operation.
