Abstract: A time-of-flight camera calibration system includes a time-of-flight camera and a calibration processor. The calibration processor is coupled to the time-of-flight camera. The calibration processor is configured to receive an input phase image captured by the time-of-flight camera, and generate a blurred phase image by applying a low pass filter to the input phase image. The calibration processor is also configured to generate a crosstalk correction matrix based on the blurred phase image, and provide the crosstalk correction matrix to the time-of-flight camera.
