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.

OV7251 是一款小尺寸、低功耗 CameraChip™ 传感器，它使用全局快门来减少或消除不需要的图像伪影，这种伪影是传统卷帘快门图像传感器在图像捕获过程中由于运动而出现的。该传感器的全局快门和出色的低光灵敏度使其可用于需要手势检测、头部和眼睛跟踪以及深度和运动检测的任何应用。
OV7251 的紧凑外形使其成为极具吸引力的相机解决方案，适用于空间受限的应用，例如头戴式显示器、智能手机、平板电脑、笔记本电脑和超极本。同样，传感器的低功耗使其成为类似应用领域的理想专用手势传感器。
利用业界最小的全局快门像素，黑白 OV7251 能够以每秒 120 帧 (fps) 的速度捕获 VGA (640×480) 分辨率的视频，通过 binning 以 180 fps 的速度捕获 QVGA (320×240) 和 QQVGA (160 ×120) 以 360 fps 合并和跳过。OV7251 的高帧速率使其成为低延迟机器视觉应用的理想解决方案。
1/7.5英寸的OV7251具有多种低功耗模式，包括光感模式和超低功耗待机模式。在光感测模式下，OV7251 的行为类似于环境光传感器 (ALS)，仅在检测到光变化时才会将传感器从“睡眠模式”唤醒。同样，在超低功耗模式下，传感器可以降低分辨率和帧率以进一步降低功耗。
