描述 Description

OmniVision's OV9738 is a 1/9 inch, 1.4 micron RGB-Ir image sensor that combines RGB and infrared (IR) imaging capabilities in a single chip for improved performance at lower system cost. Leveraging OmniVision's PureCel?Plus technology, the OV9738 reduces color crosstalk to capture high-quality color images and video.

This single-chip solution makes biometric authentication applications such as Windows? Hello affordable for a broader range of devices because it only requires a single camera. The sensor is ideally suited for bringing IR biometric capabilities for facial recognition and gesture tracking to mainstream laptops and handheld consumer-electronic devices.

The OV9738 offers 720p resolution at 30 frames per second. Additionally, it includes OmniVision's industry-leading RGB-Ir technology for improved quantum-efficiency performance in near-IR light, which can help reduce LED power consumption. At the same time, the OV9738 uses PureCel?Plus technology to reduce color crosstalk, which helps provide the best possible color-reproduction quality.

This sensor is available in chip on board (COB) and reconstructed wafer (RW) formats.
