Low Power and Compact CameraChip™ Sensor with Industry's Smallest Global Shutter Pixel

The OV7251 is a small form factor, low power CameraChip™ sensor that uses a global shutter to reduce or eliminate unwanted image artifacts, which occur with traditional rolling shutter image sensors as a result of motion during image capture. The sensor’s global shutter and excellent low-light sensitivity allow it to be used for any application that has a need for gesture detection, head and eye tracking, and depth and motion detection.

The OV7251’s compact form factor makes it a highly attractive camera solution for space-constrained applications such as head-mounted displays, smartphones, tablets, notebooks and Ultrabooks. Likewise, the sensor’s low-power consumption makes it an ideal dedicated gesture sensor for similar application areas.

Leveraging the industry’s smallest global shutter pixel, the black and white OV7251 is capable of capturing VGA (640×480) resolution video at 120 frames per second (fps), QVGA (320×240) at 180 fps with binning, and QQVGA (160×120) at 360 fps with binning and skipping. The OV7251’s high frame rates make it an ideal solution for low-latency machine vision applications.

The 1/7.5-inch OV7251 features multiple low-power modes, including light sensing mode and ultra-low power standby mode. In light sensing mode, the OV7251 behaves like an Ambient Light Sensor (ALS), which wakes the sensor up from “sleep mode” only when a change in light has been detected. Similarly, in ultra-low power mode, the sensor can reduce the resolution and frame rates to further reduce power consumption.
