Back-illuminated CMOS Image Sensor for Security Cameras and Industrial Applications Supports 4K High Resolution and High Sensitivity

Sony developed approximately 12.40M pixels backilluminated CMOS image sensor, "IMX226CQJ", supporting Type 1/2 and 4K (approximately 17:9 ratio).This image sensor has advantages in both high resolution and high sensitivity with back-illuminated structure 1.85 um unit pixel, and suits for next generation of 4K security camera.

 

Back-illuminated structure 1.85 um unit pixel 

Higher resolution 4K video imaging mode (4096 H x 2160 V, 60 frame/s)

Higher sensitivity and lower noise

Favorable incident light angle characteristics and F-number dependency

 

The IMX226CQJ employs approximately 12.40M effective pixels and supports 12M (4:3 ratio) and 4K (approximately 17:9 ratio).  High quality picture and fast video imaging is possible at 4K 60 frame/s with Type 1/1.9 approximately 9.03M pixels (approximately 17:9 ratio), and the specifications serve best for next generation of 4K high resolution security camera.

This image sensor provides higher quality picture and clearer imaging than full HD output image of the existing frontilluminated structure 3.75 um unit pixel, the IMX185LQJ*1.  (See photograph 1 and photograph 2.)

For the image sensor with higher pixel counts supporting 4K video or other formats, the reduced pixel size might cause sensitivity deterioration, which is crucial for security camera purpose.

The IMX226CQJ has back-illuminated structure 1.85 um unit pixel and achieves a big difference in its high sensitivity and low noise compared with the existing front-illuminated CMOS image sensor while it keeps 4K and the image size of Type 1/2.

 

The light collecting characteristics were optimized to maximize the light collecting efficiency of the back-illuminated structure.  As a result, it obtained better conditions in incident light angle characteristics (See figure 1.) and F-number dependency (See figure 2.) than the existing IMX136LQJ*2 with front-illuminated structure 2.8 um unit pixel. The light collectingThese characteristics are extremely important for security camera which often opens lens diaphragm during night-time shooting. And at the lower F-number better low light performance is possible than front-illuminated structure 2.8 um unit pixel, the IMX136LQJ. (See photograph 3.)Also, optical characteristics of this magnitude mean that the sensor can handle high power zoom lenses.
