Fast VCR software from Fastvideo¶
XIMEA offers the most compact and high speed cameras with various resolutions, frame rates, bandwidths, USB3 and PCIe interfaces, spectral sensitivities and image sensors.
These cameras, together with high quality, do provide high performance (especially with PCI-Express interface) which significantly increases the overall bandwidth and demands on the computer.
In combination with the XIMEA API/SDK software package that can be downloaded from XIMEA webpage for free, comes also an application called - CamTool.
This viewer like software allows to see the picture coming from the camera (or multiple cameras), control the supported features, develop plug in functionality and save data in different formats as images or videos.
To extend the portfolio of processing tasks that can be applied to the data coming from the camera, Fastvideo company has developed a GPU-based software to work with XIMEA cameras.
This software enables maximum performance at the highest image speed and quality, all at 8 / 10 / 12 bit (monochrome or bayer) and in real time.
Benefits of Fast VCR¶
Recently released CMOS sensors from Sony Pregius S 4th generation family offer slower and high speed models.
The high speed models like IMX542, IMX541 or IMX540 come with resolutions up to 24 Mpix and speeds above 100 Fps.
This kind of speed requires high bandwidth of PCIe interface to take full advantage of the sensor's potential.
The PCIe Gen3 with 4 or 8 lanes can sustain such data throughput from the hardware point of view.
Maintaining high resolution at high Fps can be complicated also from the software side, especially in real-time and without dropped frames.
That is where the Fast VCR software, running on NVIDIA GPU, comes handy.
Below is a description of the pipeline including high quality demosaicing with other image processing modules.
This color aspect would be helpful for streaming and broadcasting applications, digital cinema, 3D, AR and VR.
Camera control part¶
- Camera initialization (camera model, resolution, fps, etc.)
- Input bit depth and pixel format
- Image resolution and ROI (region of interest)
