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.

背照CMOS图像传感器，用于安全摄像头和工业应用，支持4K高分辨率和高灵敏度

索尼开发了大约12.40万像素的背照CMOS图像传感器，“IMX226CQJ”，支持Type 1/2和4K(大约17:9的比例)。该图像传感器具有1.85 um单位像素背光结构，具有高分辨率和高灵敏度的优点，适用于下一代4K安防摄像机。

 

背照结构1.85 um单位像素

更高分辨率的4K视频成像模式(4096 H x 2160 V, 60帧/秒)

更高的灵敏度和更低的噪声

良好的入射角特性和f数相关性

 

IMX226CQJ采用约12.40M有效像素，支持12M(4:3比例)和4K(约17:9比例)。高质量的图像和快速的视频成像可能在4K 60帧/秒，类型1/1.9约9.03MP像素(约17:9的比例)，该规格最适合下一代4K高分辨率安全摄像头。

与现有的3.75 um单位像素结构IMX185LQJ*1的全高清输出图像相比，该图像传感器提供了更高质量的图像和更清晰的图像。(见图1和图2)

对于支持4K视频或其他格式的像素数更高的图像传感器，像素大小的减少可能会导致灵敏度下降，这对于安全摄像头的目的至关重要。

IMX226CQJ的背照结构为1.85 um单位像素，与现有的前照CMOS图像传感器相比，在保持4K和1/2型图像尺寸的同时，在高灵敏度和低噪声方面有很大的不同。

 

优化集光特性，最大限度地提高背照结构的集光效率。因此，它在入射光角度特性(见图1)和f数依赖(见图2)方面比现有的前照结构2.8 um单位像素的IMX136LQJ*2获得了更好的条件。这些特性对于在夜间拍摄时经常打开镜头的安防摄像机来说是非常重要的。在较低的f(光圈)数下，IMX136LQJ的低光性能可能比2.8 um单位像素的前置照明结构更好。(见照片3)。此外，这种量级的光学特性意味着传感器可以处理高功率变焦镜头。
