CPC H04N 7/188 (2013.01) [G06V 20/588 (2022.01); H04N 5/33 (2013.01)] | 18 Claims |
1. An imaging system mounted on and used in a moving body, the imaging system comprising:
event detection circuitry configured to detect, as an event, that a luminance change of a pixel that photoelectrically converts incident light exceeds a predetermined threshold;
imaging circuitry configured to capture an image at a fixed frame rate; and
control circuitry configured to control the event detection circuitry and the imaging circuitry, wherein
the control circuitry performs control to acquire image information of a region including the event in response to the event detection circuitry detecting the event,
the event detection circuitry acquires the image,
the control circuitry detects a state of a road surface based on the image acquired by the event detection circuitry, and
the control circuitry divides the image acquired by the event detection circuitry into regions, and detects the state of the road surface based on a state change amount per unit area obtained from the image obtained by the region division.
