Title:
測距システム及び電子機器
Document Type and Number:
Japanese Patent JP7451110
Kind Code:
B2
Abstract:
A system includes a processor, a light source controlled by the processor and configured to emit a light, and an event based vision sensor controlled by the processor. The sensor includes a plurality of pixels. At least one of the plurality of pixels includes a photosensor configured to detect incident light and first circuitry configured to output a first signal based on an output from the photosensor. The first signal indicates a change of amount of incident light. The sensor includes a comparator configured to output a comparison result based on the first signal and at least one of a first reference voltage and a second reference voltage. The processor is configured to apply one of the first reference voltage and the second reference voltage to the comparator selectively based on an operation of the light source.
