The HM0360 is an ultralow power, Back Side Illuminated (BSI) CMOS Image Sensor designed for energy efficient smart vision applications, such as object-specific classification, tracking, and identification. The VGA resolution is ideal for monitoring, detection and image capture for wide field of view camera devices.
The HM0360 uses Himax Imaging’s advanced 3.6µ deep diode pixel and proprietary readout design to achieve superior low light performance while consuming only 140µA in QVGA 2FPS and approximately 7mA in VGA 60 frames per second read out mode.
To reduce camera system latency and power consumption, the HM0360 features on-chip self-oscillator, real time clock, fast initialization, <2ms frame trigger, context switching and instant frame update. The sensor provides several monitoring options with programmable interrupt thereby allowing the host processor to be placed in low power standby until notified by the sensor.
The HM0360 is available in a compact Chip Scale Package (CSP) and supports multiple power supply configurations with minimal passive components to enable a highly compact camera module design for next generation smart camera devices.
