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 20240348950 titled 'DYNAMIC VISION SENSOR IN LOW LIGHT ENVIRONMENT AND THE OPERATING METHOD THEREOF
The abstract 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 external light, amplifies the current output, and detects changes in light intensity to output an event signal.
- 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 image sensing technology for robotics and autonomous vehicles - High-speed event-based vision systems for surveillance and security applications - Real-time object tracking and motion detection in industrial automation
Problems Solved: - Improved low-light performance and energy efficiency in vision sensors - Enhanced sensitivity and responsiveness to dynamic visual stimuli - Integration of multiple components for compact and efficient sensor design
Benefits: - Faster response times and reduced processing latency - Higher accuracy and reliability in detecting visual events - Lower power consumption and longer operational lifespan
Commercial Applications: Title: "Next-Generation Dynamic Vision Sensors for Enhanced Visual Perception" This technology can be applied in industries such as automotive, robotics, surveillance, and industrial automation, offering improved performance and efficiency in visual sensing applications.
Questions about the technology: 1. How does the integration of multiple substrates improve the performance of the dynamic vision sensor? 2. What are the key advantages of using a bipolar junction transistor (BJT) device in the sensor design?
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.
