IMAGE SENSOR INCLUDING CMOS IMAGE SENSOR PIXEL AND DYNAMIC VISION SENSOR PIXEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18100392 titled 'IMAGE SENSOR INCLUDING CMOS IMAGE SENSOR PIXEL AND DYNAMIC VISION SENSOR PIXEL
Simplified Explanation
The patent application describes an image sensor that combines a CMOS image sensor (CIS) pixel, a dynamic vision sensor (DVS) pixel, and an image signal processor. Here are the key points:
- The CIS pixel includes a photoelectric conversion device that converts incident light into charges and a readout circuit that generates an output voltage based on the charges.
- The DVS pixel detects changes in the intensity of the incident light using the charges generated by the CIS pixel and outputs an event signal. It does not have a separate photoelectric conversion device.
- The image signal processor allows the photoelectric conversion device to be connected to either the readout circuit or the DVS pixel.
Potential applications of this technology:
- Surveillance cameras: The combination of CIS and DVS pixels can provide both high-resolution images and fast event detection, making it suitable for surveillance applications.
- Autonomous vehicles: The image sensor can capture detailed images while also detecting sudden changes in the environment, helping autonomous vehicles react quickly to potential hazards.
- Robotics: The sensor can be used in robots to enable them to perceive their surroundings accurately and respond to dynamic events in real-time.
Problems solved by this technology:
- Traditional image sensors either prioritize high-resolution imaging or fast event detection. This technology combines both capabilities in a single sensor, eliminating the need for separate sensors for different tasks.
- The integration of CIS and DVS pixels reduces the complexity and cost of image sensor systems, making them more accessible for various applications.
Benefits of this technology:
- Improved efficiency: The combination of CIS and DVS pixels allows for efficient image capture and event detection, reducing processing time and power consumption.
- Enhanced functionality: The image sensor can provide both high-resolution images and fast event detection, enabling a wide range of applications that require real-time perception and response.
- Cost-effective: By integrating multiple functionalities into a single sensor, the technology reduces the need for additional components, resulting in cost savings for manufacturers and end-users.
Original Abstract Submitted
An image sensor includes a CIS (CMOS image sensor) pixel, a DVS (dynamic vision sensor) pixel, and an image signal processor. The CIS pixel includes a photoelectric conversion device generating charges corresponding to an incident light and a readout circuit generating an output voltage corresponding to the generated charges. The DVS pixel detects a change in an intensity of the incident light based on the generated charges to output an event signal and does not include a separate photoelectric conversion device. The image signal processor allows the photoelectric conversion device to be connected to the readout circuit or the DVS pixel.
