DYNAMIC VISION SENSOR IN LOW LIGHT ENVIRONMENT AND THE OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18486372 titled 'DYNAMIC VISION SENSOR IN LOW LIGHT ENVIRONMENT AND THE OPERATING METHOD THEREOF
The patent application describes a dynamic vision sensor (DVS) with multiple vertically stacked substrates, including a photoelectric conversion device, a bipolar junction transistor (BJT) device, and a DVS pixel circuit.
- The DVS sensor generates charges in response to incident light from the external environment.
- The BJT device amplifies the current output from the photoelectric conversion device to output a current.
- The DVS pixel circuit detects changes in light intensity and outputs an event signal based on the current.
- The photoelectric conversion device is on one substrate, while the DVS pixel circuit is on a different substrate among the stacked substrates.
Potential Applications: - Advanced imaging systems - Robotics and autonomous vehicles - Surveillance and security systems
Problems Solved: - Enhanced sensitivity to changes in light intensity - Efficient event detection in dynamic environments
Benefits: - Improved performance in low-light conditions - Real-time event detection capabilities - Compact and versatile design
Commercial Applications: Title: "Next-Generation Dynamic Vision Sensors for Enhanced Imaging Systems" This technology can be utilized in various industries such as automotive, security, and consumer electronics for advanced imaging and event detection applications.
Questions about the technology: 1. How does the dynamic vision sensor improve event detection compared to traditional sensors? 2. What are the potential cost implications of implementing this technology in different industries?
Original Abstract Submitted
A dynamic vision sensor (DVS) including a plurality of substrates electrically connected to one another and stacked vertically includes a photoelectric conversion device configured to generate charges in response to incident light from an external environment that is external to the DVS sensor, a bipolar junction transistor (BJT) device including a base connected to the photoelectric conversion device and configured to output a current based on amplifying a current output from the photoelectric conversion device, and a DVS pixel circuit that detects a change in intensity of the incident light and to output an event signal based on the current. The photoelectric conversion device is on a first substrate among the plurality of substrates. At least part of the DVS pixel circuit is on a different substrate from the first substrate among the plurality of substrates.
