ST’s image-sensor process technologies have a class-leading pixel size that provides both high sensitivity and low crosstalk. The combination of silicon process innovation and advanced pixel architecture allows a smaller sensor pixel array on the top die, while a larger silicon area is found on the bottom die for digital-processing capabilities and features.
The new sensors are the VD55G0 (640 x 600 pixels) and the VD56G3 (1124 x 1364 pixels). The sensors measure only 2.6mm x 2.5mm and 3.6mm x 4.3mm respectively. VD55G0 and VD56G3 are the smallest on the market in relation to resolution. Low pixel-to-pixel crosstalk at all wavelengths, specifically near-infrared, ensures high contrast for better image clarity. Embedded optical-flow processing in the VD56G3 calculates movement vectors, without the need for host computer processing.
