CMOS Image Sensors for Industrial Applications Realize High Sensitivity Approximately Twice That of the Existing Product

Sony has developed the CMOS image sensors "IMX224LQR" and "IMX225LQR" for industrial applications. These new image sensors realize high sensitivity approximately twice that of the existing product (IMX238LQJ)*1.
The IMX224LQR and IMX225LQR pursue picture quality at low illumination, which is the characteristic most required by cameras for industrial applications, and realize pixels with the highest sensitivity among Sony image sensors for industrial applications*2. In addition, a minimum subject illumination of 0.005 lx or less is achieved by mounting an internal programmable gain amplifier that can support up to 72 dB. Superior performance as image sensors for industrial applications is achieved by combining new WDR (Wide Dynamic Range) technology with technology that improves sensitivity in the near infrared light region.
The new lineup includes the two types of the IMX224LQR, which has a WDR function, and the IMX225LQR, which does not have a WDR function.

  • High sensitivity characteristics using a newly developed 3.75 µm pixel (Sensitivity improved to approximately twice that of the existing product)
  • Minimum subject illumination of 0.005 lx or less (at a gain of 72 dB)
  • Improved sensitivity in the near infrared light region
  • New WDR function (IMX224LQR only)
  • Versatile interface (CMOS parallel, low-voltage LVDS serial, MIPI CSI-2)

High Sensitivity Characteristics Using A Newly Developed Pixel

Cameras for industrial applications are required to produce color images with high picture quality even under dark conditions. High sensitivity characteristics approximately twice that of the existing product (IMX238LQJ) with the same 3.75 µm pixel size have been achieved by developing a new pixel with the highest sensitivity among Sony image sensors for industrial applications.
In addition, mounting a sensor gain of 72 dB enables shooting of color images with high picture quality, even in a super-low-illumination environment of 0.005 lx.
Furthermore, combination with technology for improving sensitivity in the near infrared light region also improves picture quality under near infrared LED lighting.

New WDR Function (IMX224LQR Only)

The IMX224LQR supports a DOL (digital overlap)-type WDR 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 illumination compared to the existing multiple exposure WDR function.

Versatile Interface

The IMX224LQR and IMX225LQR are equipped with three different types of output interface (low-voltage LVDS serial, MIPI CSI-2, and CMOS parallel) to meet the diverse needs of customers. The low-voltage LVDS serial and MIPI CSI-2 interfaces have a maximum output data rate of 594 Mbps/ch (lane), and the number of output channels can be selected from 1ch, 2ch or 4ch (lane). The CMOS parallel interface has a maximum output data rate of 74.25 Mpixel/s.

We mounted the best technology currently available into the IMX224LQR and IMX225LQR in order to realize the ultimate picture quality under low illumination. When the development team members first saw the resulting images, we remember being amazed that we were able to obtain clear color images even in environments where nothing could be seen with the unaided eye, much less existing sensors.
Please give these new image sensors a try. We are confident you will be just as amazed as we were.
