Abstract
An imaging device of the present disclosure includes an event detection sensor that detects an event, and a control unit that controls the event detection sensor. Then, the control unit switches a resolution of the event detection sensor depending on a traveling state of a mobile body. Furthermore, the imaging system of the present disclosure includes an event detection sensor that detects an event; a control unit that switches a resolution of the event detection sensor depending on a traveling state of a mobile body; and an object recognition unit that performs event recognition on the basis of an event signal output from the event detection sensor.
Claims14
An imaging device comprising:
- an event detection sensor configured to detect an event, wherein the event detection sensor includes an asynchronous imaging device that detects as an event that a change in brightness in a pixel that photoelectrically converts incident light exceeds a predetermined threshold value;
- and
- a processor configured to:
- control the event detection sensor, and switch a resolution of the event detection sensor depending on a traveling state of a mobile body, wherein the imaging device is mounted on the mobile body;
- and
- set the resolution of the event detection sensor to a first resolution mode in which the resolution is relatively low or a second resolution mode in which the resolution is relatively high, depending on the traveling state of the mobile body.
An imaging system comprising:
- an event detection sensor configured to detect an event;
- an image sensor configured to perform imaging at a predetermined frame rate;
- and
- a processor configured to:
- switch a resolution of the event detection sensor depending on a traveling state of a mobile body;
- perform event recognition processing on a basis of an event signal output from the event detection sensor and image data output from the image sensor;
- and
- control, based on the event recognition processing, the event signal output from the event detection sensor, and the image data output from the image sensor when it is determined that the processor is not able to perform the recognition processing only with the event signal output from the event detection sensor.
