Type 1/2 Full HD CMOS Image Sensor for Security Cameras and Industrial Applications Achieves High Sensitivity

Sony developed optical size type 1/2 full HD CMOS image sensor for industrial applications, "IMX185LQJ". The sensor uses the technology from the EXview HAD CCD*1, and significantly improved the sensitivity in the near infrared light region. Newly developed 3.75 µm unit pixel was adopted to have high sensitivity and high signal-to-noise ratio. Also the near infrared sensitivity improved approximately 1.8 times compared to the existing products, "IMX104LQJ", using 3.75 µm unit pixel. The data output with the versatile connection interface gives options to customers to suit their operating conditions.

  • High sensitivity characteristics: (sensitivity 1120 mV)
  • Improved near infrared sensitivity: (1.8 times compared to the existing product)
  • Supporting optical size type 1/2 full HD
  • High frame rate: (10 bit 120 frame/s, 12 bit 60 frame/s)
  • Versatile output interface: (low-voltage LVDS parallel, serial, and CSI-2 serial)

Improved Sensitivity in the Visible Light and the Near Infrared Light

High picture quality at the low illumination is requested for security camera industry. In recent years, sensitivity in the near infrared light is also recognized of increasing weight. Responding to this demand, Sony developed 3.75 µm unit pixel and improved the sensitivity both in the visible light and the near infrared light.
Process technology specialized for industrial applications and newly developed pixel technology decreased characteristics degradation to significantly improve the sensitivity in the visible light and the near infrared light. This enables to identify objects clear enough even in the starlight or moonlight shooting. Even in the case of near infrared light LED used as auxiliary light, high picture quality imaging is possible.

Supporting Type 1/2 Full HD Format

The IMX185LQJ is a CMOS image sensor for industrial applications supporting optical size type 1/2 full HD for the first time.
Combination of the type 1/2 optical system and newly developed pixels, characteristics at the low illumination showed a big improvement compared with the existing product, optical size type 1/2.9 full HD "IMX136LQJ".

Frame Rate

Movie recording performance of the IMX185LQJ achieves up to 120 frame/s in 10 bit A/D conversion mode, and up to 60 frame/s in 12 bit A/D conversion mode. Optimization of the pixel and peripheral circuit at high-speed processing reduces fixed patterned noise and minimizes imaging degradation with increasing temperature.

Output Interface

The IMX185LQJ supports CSI-2 (2 lane/4 lane, RAW10, and RAW12) addition to the existing low-voltage LVDS parallel and low-voltage LVDS serial (selectable from 2 ch or 4 ch). The versatile output interface provides customers with options to suit their operating conditions.
Furthermore, it is pin compatible with the optical size type 1/2 5M-Effective pixel CMOS image sensor, "IMX178LQJ"*2, which simplifies making additions to the lineup in the type 1/2 optical system series.
