13 Mpixel CMOS image sensor integrates colour noise reduction

November 29, 2012 // By Julien Happich
The T4K37 released by Toshiba Electronics Europe is a 13 mega pixel, 1.12 micrometre, CMOS image sensor that is claimed to deliver the image quality equivalent of a 1.4 micrometre pixel image sensor.

Toshiba implemented back side illumination (BSI) technology and integrated colour noise reduction (CNR) to develop this CMOS image sensor which fits into an 8.5x8.5mm size camera module and enables high-quality pictures even in low-light conditions.

The miniaturization of pixel size impacts performance of light sensitivity and signal to noise ratio (SNR) in today's 1.12 micrometre pixel image sensors. BSI technology helps improve sensitivity, but falls short on elevating image quality. The company says the T4K37 provides approximately 1.5 times higher SNR value than a 1.12 micrometre pixel image sensor with no CNR feature, allowing manufacturers to deliver products with high-quality imagery, even in low-light conditions.
