Publication number: 20250020455Abstract: A depth sensor device for measuring a depth map of an object comprises a projector unit configured to illuminate different locations of the object during different time periods with an illumination pattern, a receiver unit comprising a plurality of pixels, the receiver unit being configured to detect on each pixel intensities of light reflected from the object while it is illuminated with the illumination pattern, and to generate an event at one of the pixels if the intensity detected at the pixel changes by more than a predetermined threshold, and a control unit configured to generate for each of the different time periods a total number of detected events and pixel information indicating for each event the pixel that detected the event, and to calculate from the pixel information and the total number a position of the image of the illumination pattern on the pixels with sub-pixel accuracy.Type: ApplicationFiled: December 5, 2022Publication date: January 16, 2025Applicant: Sony Semiconductor Solutions CorporationInventor: Marc OSSWALD
