E-con Systems bases UVC camera on onsemi CMOS image sensor
An 8M pixel USB 3.1 colour high dynamic range (HDR) camera, developed by E-con Systems is based on onsemi’s AR0821 CMOS image sensor, with integral image signal processor (ISP).
The See3CAM_CU81, 8M pixel, fixed focus UVC (USB video class) -compliant USB 3.1 camera can capture images in various lighting conditions. The USB 3.1 interface streams Full HD at 60 frames per second and 4K at 30 frames per second in linear mode and 4K at 30 frames per second in HDR mode, while UVC-compliance means no additional drivers are required for Windows and Linux operating systems.
The 4K camera’s HDR capability uses multiple exposures in a single frame to bring out details in the brightest as well as darkest areas of the same scene in high-contrast lighting conditions.
The See3CAM_CU81 has an inbuilt ISP that performs the auto functions, i.e., auto white balance, auto exposure.
High signal to noise ratio helps the camera to produce videos and images with low noise even in poor lighting conditions, says E-con Systems. The camera also has an M12 (S-mount) lens which allows customers to choose the lens of choice according to application needs.
In addition to HDR and 4K ultra-HD resolution, the See3CAM_CU81 has large pixel size and high signal to noise ratio (SNR), making it suitable for applications that require big data analytics, such as digital signage, biometric and access control, sports broadcasting and analytics, smart surveillance and smart traffic management.
See3CAM_CU81 is a ready-to-manufacture camera board, complete with all the necessary firmware and is compatible with the USB Video Class (UVC) version 1.0 standard. The camera board will work with the standard drivers available in Windows and Linux OS without any additional driver installation, says E-con Systems.
The camera is exposed as DirectShow capture source to Windows PC. E-con Systems provides a sample DirectShow application, called e-CAMView for video streaming and still capturing from the USB camera device with a graphical user interface (GUI). In Linux, See3CAM_CU81 is exposed as a V4L2 camera and E-con Systems provides a sample application called QtCAM for streaming.
Customers can also develop customised applications for See3CAM_CU81 using standard V4L2 APIs. The e-CAMView and QtCAM applications enable controls such as brightness, contrast, sharpness, saturation, gamma, gain, exposure (manual and auto), and white balance (manual and auto).
