产品介绍
The HM01B0 is an ultralow power CMOS Image Sensor that enables the integration of an “Always On” camera for computer vision applications such as gestures, intelligent ambient light and proximity sensing, tracking and object identification. The unique architecture of the sensor allows the sensor to consume very low power of <2mW at QVGA 30FPS.
The HM01B0 contains 320 x 320 pixel resolution and supports a 320 x 240 window mode which can be readout at a maximum frame rate of 60FPS, and a 2×2 monochrome binning mode with a maximum frame rate of 120FPS. The video data is transferred over a configurable 1 bit, 4bit or 8bit interface with support for frame and line synchronization. The sensor integrates black level calibration circuit, automatic exposure and gain control loop, self-oscillator and motion detection circuit with interrupt output to reduce host computation and commands to the sensor to optimize the system power consumption.
The sensor is available in a Chip Scale Package (CSP) or bare die and measures less than 5mm2. The sensor supports single, dual or triple power supply configuration and requires only 3 passive components enabling a highly compact camera module design for devices such as IoT, wearable, smart building, smartphone, tablets and slim notebooks.
