Sony IMX323 Image Sensor

In addition to providing good image quality video in the daytime, Sony CMOS image sensors can capture superior image quality video at night. Its night performance is better than similar image sensors from the counterparts such as OmniVision and ON Semiconductor (formerly Aptina).

Recently, Sony has begun to mass produce the IMX323LQN, which is a 1/2.9-inch progressive scan CMOS image sensor delivers total 2.19-megapixel resolution. The IMX323 is the replacement of current IMX322, it achieves a compact package size by utilizing WLCSP (Wafer level chip size package) technology. Based on the published document by Sony, the IMX323 delivers the exact same image quality and low-light performance like its predecessor - IMX322. However, the gain sensitivity of IMX323 is 45 dB, that's higher than IMX222 (42 dB). The cost of IMX323 is lower than existing IMX222, and this helps security manufacturers to develop cost-effective products.

IMX322 vs IMX323

We expect Sony IMX323 will be widely used in Full HD 1080p security camera include analog and IP. End-users will find 1080p AHD cameras based on Sony IMX323 + NVP2441/NVP2440; 1080p HD-TVI cameras based on Sony IMX323 + EN773E + TP9801; 1080p IP cameras based on Hi3516C/GK7101.


IMX323 is a 1/2.9 inch 2.19 megapixel CMOS image sensor, it achieves a compact package size by utilizing WLCSP (Wafer level chip size package) technology. However, IMX323 still can maintain low illumination performance equal to that of the predecessor SONY IMX222 that offered ehanced sensitivity in the near IR region for video surveillance & security applications.
