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.

Back-illuminated Structure CMOS Image Sensor for Security Cameras and Industrial Applications Achieves High Sensitivity and High Dynamic Range
Sony developed back-illuminated structure CMOS image sensor, "IMX178LQJ", supporting three formats of 4:3, 5:4, and 16:9 ratio with type 1/2 in 5M-effective pixel. Adopting back-illuminated structure with 2.4 µm unit pixel and 14 bit ADC, it provides all three advantages of high resolution, high sensitivity, and high dynamic range, which are necessary for security cameras.
