Abstract
Provided are a sensor module including an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light, and an actuator connected to the sensor array and configured to displace the sensor array in a predetermined direction, and an electronic device having such a sensor module.
Claims7
A sensor module comprising:
- an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light;
- an actuator connected to the sensor array and configured to displace the sensor array in a predetermined direction in order to cause an appearance of movement by at least one object and to invoke the change in intensity of incident light and the event signal even when the at least one object is stationary;
- and
- a control unit that receives the event signal and detects a subject from the event signal, transmits a control signal for displacing the sensor array in the predetermined direction to the actuator, and detects the subject from the event signal generated after the control signal is transmitted.
An electronic device comprising:
- a sensor module including an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light;
- an actuator connected to the sensor array and configured to displace the sensor array in a predetermined direction in order to cause an appearance of movement by at least one object and to invoke the change in intensity of incident light and the event signal even when the at least one object is stationary;
- and
- a control unit that receives the event signal and detects a subject from the event signal, transmits a control signal for displacing the sensor array in the predetermined direction to the actuator, and detects the subject from the event signal generated after the control signal is transmitted.
A subject detection method by using an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light, the method comprising:
- driving an actuator connected to the sensor array to displace the sensor array in a predetermined direction in order to cause an appearance of movement by at least one object and to invoke the change in intensity of incident light and the event signal even when the at least one object is stationary;
- and
- detecting a subject from the event signal, transmitting a control signal for displacing the sensor array in the predetermined direction to the actuator, and detecting a subject from the event signal generated after the sensor array is displaced.
A non-transitory, computer readable storage medium containing a computer program, which when executed by a computer, causes a processing circuit connected to an event-driven vision sensor that includes a sensor array having a sensor that generates an event signal when the sensor detects a change in intensity of incident light to carry out actions, comprising:
- driving an actuator connected to the sensor array to displace the sensor array in a predetermined direction in order to cause an appearance of movement by at least one object and to invoke the change in intensity of incident light and the event signal even when the at least one object is stationary;
- and
- detecting a subject from the event signal, transmitting a control signal for displacing the sensor array in the predetermined direction to the actuator, and detecting a subject from the event signal generated after the sensor array is displaced.
