Patent ID: 11863911
Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A method of controlling an imaging system, the method comprising:
detecting, by event detection circuitry, as an event, that a luminance change of a pixel that photoelectrically converts incident light exceeds a predetermined threshold;
capturing, by imaging circuitry, an image at a fixed frame rate;
controlling the event detection circuitry and the imaging circuitry, wherein the controlling performs control to acquire image information of a region including the event in response to the event detection circuitry detecting the event;
acquiring, by the event detection circuitry, the image;
detecting a state of a road surface based on the image acquired by the event detection circuitry;
dividing the image into regions; and
detecting the state of the road surface based on a state change amount per unit area obtained from the image obtained by the region division.
