HM11B1 HD Sensor for Always On Vision Ultra Slim Camera Applications

Stacked BSI 1280 x 800 60FPS 1/11″ 40mW 720p60 <1mW AONV & Monitor Mode

The HM11B1 is an ultra-low power 1/11” HDCMOS image sensor designed with Himax Imaging Ultrasense-AoSTM stacked technology that delivers exceptional image quality performance and integration. The sensor package measures only 2.3mm x 1.5mm for module y-dimension as small as 2.2mm to support thin bezel HD notebook and small form factor IoT devices.

The HM11B1 consumes approximately 40mW at 60 frames per second operation and features sub-milliwatt readout modes and embedded Wake-on-Motion monitoring over the entire field of view. The HM11B1 ultra low power readout and sensing modes can be triggered by the host or operated autonomously to enable Always-On contextual awareness for next generation computer vision features, such as wake on human-detected approach.

To further reduce the camera power consumption and system latency, the HM11B1 offers fast boot up time, <50ms time to well-exposed frame output (typical case and includes 33ms exposure time assumption), context switching and instant frame update.

The HM11B1 is offered in Bayer RGB, 4×4 RGB-IR and White-IR filter array. The RGB-IR sensor can be used to support active illumination in dark conditions or support system authentication reliant on IR information. The sensor features separate analog gain amplifier for visible and IR channel to compensate for response differences in the scene illumination.

Additionally, the sensor offers flexible readout, including multiple sensor binning modes to reduce data bandwidth while improving signal to noise ratio, and option for visible only or IR only readout (RGB-IR sensor only). The HM11B1 supports MIPI-CSI2 interface and Serial Digital Interface (SDI) that can interface to a secondary AI CV processor. The data interfaces can run independently or simultaneously (dual mode). In dual mode, the sensor allows lower frame rate at SDI output while operating at 30 or 60 frames per second over the MIPI interface.

The HM11B1 supports 3 power supply configurations for the lowest power consumption, and support 2 supply or 1 supply configuration to simplify system power design. The sensor requires minimal passive components to enable a highly compact camera module design for next generation computing and smart camera devices.
