![]() Two 3.3V-to-1.2~3.1V adjustable regulators convert 3.3V power for the sensor’s IO and analog power. The RTS5822 integrates five regulators to save BOM cost and PCB area. The internal scaling filter can scale down higher resolutions for size reduction purposes, and also scale up a VGA image to 800圆00, 960x720, 1024x7x960 resolution. These functions help compensate for intrinsic inaccuracy in lens and image sensors to provide better image quality. In addition, this engine also has offers functions such as Lens Shading Correction, dead pixel cancellation, G1G2 filter, Color Correction Matrix, histogram statistic Auto White Balance, scaling function and so on. This helps speed software updating.Ī new generation ISP (Image Signal Processing) engine supports most UVC defined image adjustments. With the external Serial-Flash interface, the internal program ROM can be fully replaced and the control firmware can be easily accessed via the USB link. The RTS5822 supports an internal MCU program ROM, external NOR-Flash interface, and external Serial-Flash interface. The RTS5822 is designed to support various types of access interface to achieve the best compatibility with major SOC CMOS image sensors. It supports most available CMOS sensors from VGA (640x480) to QXGA (2048x1536) resolution. The RTS5822 integrates a USB 2.0 transceiver that is optimized for high performance data transfer rate, high speed MCU (Micro Processor Unit), DC-to-DC regulators, sensor controller, image signal processing engine, MJPEG compression, and Analog-to-Digital converter for analog microphone into a single chip. It is fully compatible with the USB Video Class, and operates with native drivers provided in Windows XP, Windows Vista, Windows 7, and Windows 8 operating systems. The built-in extremely low-power transceiver provides superior compatibility with USB hosts and high quality for image applications. The RTS5822 is a USB 2.0 compatible camera controller designed for notebook and desktop PCs.
