A sensor control apparatus comprising: a readout control section configured to send a control signal to an event-driven vision sensor comprising a sensor array comprising a plurality of sensors that are configured to generate event signals when a change in incident light intensity is detected, and two address generators (131, 132) configured to generate an address for each sensor, wherein each address is respective identification information for each sensor, and periodically perform a readout on the sensors, wherein, for a given readout, if a given sensor has generated an event signal when the given readout is being performed on the given sensor, then the event signal is read out according to the address generated for the given sensor, otherwise no event signal is read out from the given sensor, after which performance of the given readout progresses onto a sensor adjacent to the given sensor, wherein the control signal is based on region information comprising at least one of an address range indicating a first region of the sensor array and an address range indicating a second region of the sensor array, wherein the two address generators are configured to control, in response to the received control signal, the periodicity of the readout such that readout of event signals is performed at a first frequency on the first region and readout of event signals is performed at a second frequency higher than the first frequency on the second region; and a region setting section configured to update the region information by changing at least part of the first region to the second region on a basis of the number of first event signals acquired by the readout in the first region within a given period of time or by changing at least part of the second region to the first region on a basis of the number of second event signals acquired by the readout in the second region within the given period of time. a readout control section configured to send a control signal to an event-driven vision sensor comprising a sensor array comprising a plurality of sensors that are configured to generate event signals when a change in incident light intensity is detected, and two address generators (131, 132) configured to generate an address for each sensor, wherein each address is respective identification information for each sensor, and periodically perform a readout on the sensors, wherein, for a given readout, if a given sensor has generated an event signal when the given readout is being performed on the given sensor, then the event signal is read out according to the address generated for the given sensor, otherwise no event signal is read out from the given sensor, after which performance of the given readout progresses onto a sensor adjacent to the given sensor, wherein the control signal is based on region information comprising at least one of an address range indicating a first region of the sensor array and an address range indicating a second region of the sensor array, wherein the two address generators are configured to control, in response to the received control signal, the periodicity of the readout such that readout of event signals is performed at a first frequency on the first region and readout of event signals is performed at a second frequency higher than the first frequency on the second region; and a region setting section configured to update the region information by changing at least part of the first region to the second region on a basis of the number of first event signals acquired by the readout in the first region within a given period of time or by changing at least part of the second region to the first region on a basis of the number of second event signals acquired by the readout in the second region within the given period of time.
