Aptina has declared that its 16megapixel MT9H004 image sensor is a finalist at the 2010 EDN Innovation Award competition. It uses the DR-Pix technology and can deliver high signal-to-noise ratio (SNR) across all scene lighting and ISO-certified speed environments.
The DR-Pix technology incorporates two types of operation in one pixel design with the help of a dual conversion gain switch and an extra pixel level. The first is a high conversion gain mode featuring enhanced sensitivity and low read noise suitable for low and ambient light conditions. The second is a low conversion gain mode suitable for higher capacity for charge handling in brightly lit conditions.
A 5dB hike in SNR, almost two full f-stops of range for the lens aperture is possible using the sensor in ambient light environments without compromising on clarity in bright conditions. Under bright conditions, it can deliver a 47dB SNR. It also captures 16MP still photos at 10fps, and features live-view video support, and 1080p/30fps HD video recording.
