The depth camera component is used to obtain depth information describing the local region. The depth camera assembly includes a sensor having a plurality of pixels. Some or all of the pixels are divided into groups coupled to respective multi-purpose time-to-digital converters. Each multipurpose time-to-digital converter includes an oscillator and a counter. Each pixel in a group is associated with a multiplexer configured to select between inputs coupled to the pixel, an oscillator, or a counter associated with a different pixel. The multiplexer outputs the signal to a counter of a time-to-digital converter associated with the pixel. Time-of-flight measurements are made during a first portion of the image frame. During the second portion of the image frame, the sensor may act as an intensity counter. During a third portion of the image frame, the depth sensor may be calibrated.)
