Toshiba Unveils a New CMOS Sensor
Toshiba has released a new CMOS image sensor with a 0.25 inch optical format. This new sensor has the smallest pixel size to date of 1.12 micrometers and delivers cutting edge peformance with its built in back-side illumination technology.
The sensor has been designed to accomodate tight form factors and still capture high definition images. Due to this feature, the company expects it to be embedded into mobile devices such as cameras, smartphones, tablets and even laptops in the near future. The 8.08 MP sensor can capture video at 60 frames per second at both 720p and 1080p resolutions.
Andrew Burt, vice president, Analog and Imaging Business Unit, System LSI Group, TAEC had this to say,
As smartphones and other portable digital devices move to smaller form factors, image sensors must also shrink in size. This presents imaging subsystem designers with a challenge: how do you get smaller and smaller image sensors to support higher image resolutions when miniaturization can cause a fall off in performance? Our BSI technology overcomes this problem by deploying the lens on the rear of the sensor, on its silicon substrate, not on the front, where wiring limits light absorption. This positioning boosts light sensitivity and absorption, and allows Toshiba to make finer quality image pixels in smaller-sized CMOS image sensors. This increased sensitivity also makes our BSI CMOS image sensors more suitable for video applications, such as video capture or video chat.
