VISION SENSORS, IMAGE PROCESSING DEVICES INCLUDING THE VISION SENSORS, AND OPERATING METHODS OF THE VISION SENSORS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18341968 Titled 'VISION SENSORS, IMAGE PROCESSING DEVICES INCLUDING THE VISION SENSORS, AND OPERATING METHODS OF THE VISION SENSORS'
Simplified Explanation
This abstract describes a vision sensor that consists of a pixel array, an event detection circuit, an event rate controller, and an interface circuit. The pixel array is made up of pixels arranged in a matrix, and each pixel can generate an electrical signal when it detects a change in incident light intensity. The event detection circuit processes these electrical signals to determine if any changes in light intensity have occurred at any pixels, and generates event signals accordingly. The event rate controller selects a subset of these event signals that correspond to a specific region of interest on the pixel array. Finally, the interface circuit connects the sensor to an external processor and transmits the selected event signals to the processor.
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.
