OV7251VGA product brief  
Low Power and Compact CameraChip™ Sensor  
with Industry's Smallest Global Shutter Pixel  
lead free  
available in  
a lead-free  
package  
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.  
second (fps), QVGA (320x240) at 180 fps with binning,  
and QQVGA (160x120) 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.  
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 (640x480) resolution video at 120 frames per
