As the main camera, the OV4682 is the eye of Project Tango’s mobile device. The OV4682 is a 4MP RGB IR image sensor that captures high-resolution images and video as well as IR information, enabling depth analysis. The sensor features a 2um OmniBSI-2 pixel and records 4MP images and video in a 16:9 format at 90fps, with a quarter of the pixels dedicated to capturing IR. From the product page: "The sensor's 2-micron OmniBSI-2 pixel delivers excellent signal-to-noise ratio and IR sensitivity, and offers best-in-class low-light sensitivity with a 40 percent increase in sensitivity compared to the 1.75-micron OmniBSI-2 pixel. The OV4682's unique architecture and pixel optimization bring not only the best IR performance but also best-in-class image quality. Additionally, the sensor reduces system-level power consumption by optimizing RGB and IR timing."
The OV7251 CameraChip sensor is capable of capturing VGA resolution video at 100fps using a global shutter. The low-power VGA sensor provides excellent low-light sensitivity and motion tracking information for device orientation data.
