A time-of-flight (ToF) camera is configured to illuminate a subject with IR light. For each sensor of a sensor array, camera space coordinates of a locus of the subject are determined based on the measured IR light. The camera space coordinates include a phase difference between emitted IR light and reflected IR light. A plurality of candidate positions of the locus of the subject are determined in world space based on the camera space coordinates. Each candidate position corresponds to a different phase wrapping of the phase difference. A phase wrapping is determined based on performing a searching algorithm on the different candidate positions. A depth value for the sensor is calculated based on the phase difference and the phase wrapping determined from performing the searching algorithm. A matrix of pixels is outputted from the camera. Each pixel of the matrix includes a depth value.
