The SN9C2895Q is a FHD RGB-IR/RGB+IR Webcam controller with better image quality because of
improved image quality and also the integrated temporal and new spatial noise-reduction circuits. It not only
brings noise-free image for human eye but also makes the analysis work in machine-vision easier and more
rOBUst.
SN9C2895Q also supports two different IR sources, one is from RGB-IR and the other is from IR sensor.
RGB-IR sensor is usually used with 850nm IR pass while 940nm IR pass is used with a standalone IR
sensor. So SN9C2895Q can well support Microsoft windows 10 Hello certification. With IR path output, the
host OS can use the RGB image together with IR image to do face recognition. This is the latest secure
biometrics mechanism used by Microsoft.
The major functions of SN9C2895Q include of controlling one or two CMOS sensors, receiving the image
data, converting it to video stream, and then sending data to the host via USB. It’s compliant with USB 2.0
High-Speed (HS) and USB Video Class (UVC) 1.1. Compliance with the public standards makes
SN9C2895Q easy to be integrated into various fields of applications that need high quality video like NB
built-in camera, camcorder, surveillance, video conference and machine vision.
SN9C2895Q only supports maximum two MIPI-CSI2 CMOS sensor interfaces and the resolution of ISP
output is up to 1920x1088@30fps in RGB path and up to 1280x720 @30fps in IR path. Besides the
excellent noise-reduction, this generation of ISP supports wide dynamic range (WDR) to bring better visual
experience. The high performance Motion-JPEG engine and bit rate controller provides various compression
ratios to meet bandwidth requirement. This sys-tem is controlled by the embedded micro-controller and
built-in statistics of AE / AWB / AF / AB. The flexible architecture includes the mask ROM, internal RAM
and external serial-flash which can store the customized codes and parameters.
There are 3 built-in regulators and no needs of external oscillator, these features make it able to further save
BOM and PCB area. SN9C2895Q is the best choice for the compact modern electronic product design.
