DEPTH BASED DYNAMIC VISION SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240267650 titled 'DEPTH BASED DYNAMIC VISION SENSOR
The patent application describes an image sensor designed for use in augmented reality systems, offering low latency image analysis with minimal power consumption. The sensor includes multiple pixel cells, each containing a photodetector that generates an electric signal based on incident light intensity. Additionally, subsets of pixel cells feature angle-of-arrival to-intensity converters to modulate light based on the angle of arrival. The sensor also includes differential readout circuitry to output signals only when there is a change in the photodetector's electric signal amplitude.

Original Abstract Submitted
an image sensor suitable for use in an augmented reality system to provide low latency image analysis with low power consumption. the image sensor may have multiple pixel cells, each of the pixel cells comprising a photodetector to generate an electric signal based on an intensity of light incident upon the photodetector. the pixel cells may include multiple subsets of pixel cells, each subset of pixel cells including at least one angle-of-arrival to-intensity converter to modulate incident light reaching one or more of the pixel cells in the subset based on an angle of arrival of the incident light. each pixel cell within the plurality of pixel cells may include differential readout circuitry configured to output a readout signal only when an amplitude of a current electric signal from the photodetector is different from an amplitude of a previous electric signal from the photodetector.
