A dual sensor camera is a type of imaging device designed to capture multiple video streams simultaneously by utilizing more than one sensor. Based on the provided reference, a specific implementation of a dual sensor camera has a beam splitter and two CCD sensors.
Core Components
At the heart of this specific dual sensor camera design are two key elements:
- Beam Splitter: This optical component divides incoming light rays into two separate paths.
- Two CCD Sensors: Charged Coupled Device (CCD) sensors are light-sensitive chips that convert light into electronic signals, forming an image. This camera uses two of them.
How it Works
The beam splitter plays a crucial role by dividing an incident ray into the two CCDs. This means that light entering the camera is split, and each resulting path is directed towards one of the two independent CCD sensors.
Simultaneous Video Capture
One of the primary capabilities of this configuration is its ability to capture two video sequences simultaneously. Since the light is split and sent to two separate sensors, each sensor can operate independently to record video data.
Output Capabilities
The dual sensor camera described can utilize its two CCDs to capture video sequences with different characteristics concurrently:
- High Resolution Video: One sensor can be configured to capture video with high image detail but typically at a low frame rate.
- Low Resolution Video: The other sensor can be configured to capture video with less detail but at a high frame rate.
| Video Output | Resolution | Frame Rate |
|---|---|---|
| Sequence 1 (via CCD) | High | Low |
| Sequence 2 (via CCD) | Low | High |
Practical Insights
This dual capability allows the camera to serve applications where both detailed inspection and rapid movement tracking are necessary at the same time. For instance, one video stream provides the fine detail (high resolution, low frame rate), while the other captures fast action (low resolution, high frame rate). This combined information can be processed together for comprehensive analysis.
