Sony to Release Two 4K-Resolution CMOS Image Sensors for Security Cameras
Sony today announced the upcoming release of two new models of CMOS image sensors: the IMX415 type 1/2.8 4K-resolution stacked CMOS image sensor, and the IMX485 type 1/1.2 4K-resolution back-illuminated CMOS image sensor.
Sony has designed these two new sensors for security cameras for the smart city market.
In general, as pixel miniaturization progresses, the light collection efficiency per pixel deteriorates and sensitivity decreases. Sony's new IMX415 stacked CMOS image sensor employs proprietary high-sensitivity, low-noise technology to miniaturize the pixel size to 1.45 square μm, which is approximately 80% smaller than conventional. The result is the world’s smallest type 1/2.8 4K-resolution stacked CMOS image sensor yet with great low-light performance.
Sony's IMX485 is a back-illuminated CMOS image sensor with even better low-light performance. By employing the latest pixel technology for low-noise capabilities, this sensor achieves a low-light performance 3.3 times higher than conventional for a 4K-resolution sensor.
