A light-emitting module emits a first light pulse to a sensing target, and a sensing unit receives and integrates a first reflected light pulse of the sensing target. A processing circuit reads an image parameter of the sensing target through a readout circuit. The light-emitting module emits a second light pulse to the sensing target, and the sensing unit receives a second reflected light pulse of the sensing target. The processing circuit obtains a distance parameter between the sensing target and the time of flight device according to a time when the readout circuit reads the second reflected light pulse of the sensing unit. The processing circuit obtains a reflectivity of the sensing target according to the image parameter and a look-up table, and obtains a corrected distance parameter of the sensing target by correcting the distance parameter according to the reflectivity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time of flight device and time of flight method","description":"Time of flight device and method are provided.
