> Colour global-shutter CMOS image sensors for multi-camera robots, headsets, grippers, drones and capture rigs.

GS2.3 is a 2.3 MP (1920 × 1200) backside-illuminated charge-domain global shutter, 4.0 µm pitch, with a 4.5 µm option. Design targets: 90 frames a second with both HDR paths read, at least 80 dB linear range in one exposure, high-gain read noise at most 2.0 e−, and SyncLink multi-camera timestamps.

Figures are design targets until silicon is measured to EMVA 1288.
