Depth sensor device and method for operating depth sensor device

A depth sensor device (1000) for measuring a depth map of an object (O) comprises: a projector unit (1010) configured to illuminate different positions of the object (O) with an illumination pattern during different time periods; a receiver unit (1020) comprising a plurality of pixels, the receiver unit (1020) configured to detect, on each pixel, an intensity of light reflected from the object (O) while illuminating the object (O) with the illumination pattern, and to generate an event at one pixel if a change in the intensity detected at that pixel exceeds a predetermined threshold; and a control unit (1030) 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 for which the event was detected, and to calculate, at sub-pixel accuracy, the position of the image (I) of the illumination pattern on the pixel as a function of the pixel information and the total number. 一种用于测量物体(O)的深度图的深度传感器设备(1000)包括：投影仪单元(1010
