Abstract
An apparatus for determining distance information. The apparatus includes a control module configured to control a transmission of a request signal by a transmit module. The request signal includes information related to a request for information related to a light modulation of a modulated light emitted by a time of flight light source. The control module is configured to provide a modulation reference signal to a time of flight sensor circuit for determination of distance information after the request for information related to the light modulation. The modulation reference signal is based on a receive signal received by a receiver module from the time of flight light source.
Claims17
An apparatus for determining distance information, the apparatus comprising:
- a control circuit configured to control a transmission of a request signal by a transmit module, wherein the request signal comprises information related to a request for information related to a light modulation of a modulated light emitted by a time of flight light source that is external to the apparatus, and
- wherein the control circuit is configured to provide a modulation reference signal to a time of flight sensor circuit located within the apparatus in response to the request for information related to the light modulation, wherein the modulation reference signal is based on a receive signal received by a receive circuit from the time of flight light source in response to the request signal.
Time of flight light source, comprising
- a time of flight light source circuit configured to emit modulated light;
- and
- a control circuit configured to control a transmission of a modulation signal comprising information related to a modulation of the modulated light emitted by the time of flight light source circuit to at least two devices comprising a time of flight sensor circuit.
