VISION SENSORS, IMAGE PROCESSING DEVICES INCLUDING THE VISION SENSORS, AND OPERATING METHODS OF THE VISION SENSORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18059469 titled 'VISION SENSORS, IMAGE PROCESSING DEVICES INCLUDING THE VISION SENSORS, AND OPERATING METHODS OF THE VISION SENSORS
Simplified Explanation
The patent application describes a vision sensor that includes a pixel array, event detection circuit, event rate controller, and interface circuit.
- The pixel array consists of pixels arranged in a matrix, and each pixel generates an electrical signal when it detects a change in incident light intensity.
- The event detection circuit processes the electrical signals from the pixels to determine if a change in light intensity has occurred at any pixel, and generates event signals for the pixels where a change is detected.
- The event rate controller selects a subset of event signals from a region of interest on the pixel array as output event signals.
- The interface circuit communicates with an external processor to transmit the output event signals.
Potential applications of this technology:
- Motion detection: The vision sensor can be used to detect motion in a specific region of interest, making it useful for security systems or surveillance cameras.
- Object tracking: By analyzing the output event signals, the sensor can track the movement of objects within the field of view.
- Gesture recognition: The sensor can be utilized to recognize and interpret hand gestures, enabling touchless control of devices or interactive displays.
Problems solved by this technology:
- Efficient event detection: The sensor only generates event signals when a change in light intensity is detected, reducing the amount of data processing required.
- Selective output: The event rate controller allows for the selection of specific event signals from a region of interest, minimizing the amount of data transmitted to the external processor.
Benefits of this technology:
- Low power consumption: The sensor only activates and generates signals when there is a change in light intensity, resulting in energy efficiency.
- Real-time processing: The event detection and selection of output signals can be performed in real-time, allowing for immediate response and analysis.
- Reduced data transmission: By transmitting only the selected output event signals, the amount of data sent to the external processor is minimized, improving overall system efficiency.
Original Abstract Submitted
A vision sensor includes a pixel array comprising pixels arranged in a matrix, an event detection circuit, an event rate controller, and an interface circuit. Each pixel is configured to generate an electrical signal in response to detecting a change in incident light intensity. The event detection circuit detects whether a change in incident light intensity has occurred at any pixels, based on processing electrical signals received from one or more pixels, and generates one or more event signals corresponding to one or more pixels at which a change in intensity of incident light is determined to have occurred. The event rate controller selects a selection of one or more event signals corresponding to a region of interest on the pixel array as one or more output event signals. The interface circuit communicates with an external processor to transmit the one or more output event signals to the external processor.
