CMOS Image Sensor for Industrial Applications that Realizes High Sensitivity Approximately Twice That of the Existing Product

Sony Semiconductor Solutions Corporation has developed the CMOS image sensor "IMX385LQR" for industrial applications. This new image sensor realizes high sensitivity approximately twice that of the existing product (IMX185LQJ)*1.
The IMX385LQR pursues picture quality at low illuminance most needed by cameras for industrial applications and mounts pixels with a sensitivity of 2350 mV, which is the highest sensitivity among Sony image sensors for industrial applications*2. In addition, SNR1s of 0.13 lx*3, which is the highest performance among Sony Full HD-compatible image sensors for industrial applications, is achieved by mounting an internal programmable gain amplifier and high conversion gain pixels. Superior performance as an image sensor for industrial applications is further achieved by combining HDR (High Dynamic Range) technology with technology that improves sensitivity in the near-infrared light region.

  • High sensitivity characteristics using a new-generation 3.75 µm pixel (Sensitivity improved to approximately twice that of the existing product)
  • Overwhelming low illuminance performance of SNR1s: 0.13 lx
  • DOL-HDR function
  • Versatile interface (Low-voltage LVDS serial, MIPI CSI-2)

Overwhelming low illuminance performance

Cameras for industrial applications are required to produce color images with high picture quality even in dark conditions. High sensitivity characteristics of 2350 mV, which is approximately twice that of the existing Type 1/2 Full HD product (IMX185LQJ) with the same 3.75 µm pixel size have been achieved by mounting a new pixel with the highest sensitivity among Sony image sensors for industrial applications.
In addition, mounting high conversion rate pixels achieved SNR1s of 0.13 lx, which is the highest performance among Sony Full HD-compatible image sensors for industrial applications.
Furthermore, combination with technology for improving sensitivity in the near infrared light region also improves picture quality under near-infrared LED lighting.

DOL-HDR function

The IMX385LQR supports a DOL (digital overlap) -type HDR function. This function uses a method that outputs the data for three frames with different storage times line by line instead of frame by frame, enabling improvement of picture quality especially under low illuminance when compared to the existing multiple exposure HDR function.

Versatile interface

The IMX385LQR is equipped with two different types of output interface (low-voltage LVDS serial, MIPI CSI-2) to meet the diverse needs of customers. The low-voltage LVDS serial interface has a maximum output data rate of 445.5 Mbps/ch, and the number of output channels can be selected from 1 ch, 2 ch, or 4 ch. The MIPI CSI-2 interface has a maximum output data rate of 742.5 Mbps/lane, and the number of output lanes can be selected from 1 lane, 2 lanes, or 4 lanes.
