ZA20S10 - Full HD 1080P CMOS Sensor + ISP

ZeeAnn, headquartered in Gyeonggi-do Korea, the company is a pioneer CMOS image sensor developer and manufacturer. Although ZeeAnn is not as famous as its competitors such as Aptina, OmniVision, Panasonic, Sony, the company gained reputation by launching the innovative HD CMOS image sensors integrate image signal processor design. Since the establishment in 2009, the company successfully released ZN220, ZA10S30, ZA20S10, ZA10S20, ZA10S10 models.

CMOS Sensor + ISP Concept

It's the same with CMOS image sensors, an image signal processor is essential component to achieve video capturing. Different from the conventional CMOS image sensors, ZeeAnn products, embedded ISP(Image Signal Processor) in a sensor chip, which can greatly reduce the complexity of cameras development, also reduce the hardware cost and maintain high image quality.

Today, you can find many Full HD 1080p cameras utilize ZeeAnn CMOS image sensors, such as ZA20S10 + Eyenix EN672 hardware design for IP cameras, ZA20S10 + Eyenix EN331 for HD-SDI cameras, ZA20S10 + Techpoint TP2801 for HD-TVI cameras.
