An imaging system of the present disclosure includes an event detection device that detects, as an event, that a luminance change of a pixel that photoelectrically converts incident light exceeds a predetermined threshold, an imaging device that captures an image at a fixed frame rate, and a control section that controls the event detection device and the imaging device, and is mounted on and used in a moving body. Then, the control section performs control to acquire image information of a region including the event by the imaging device in response to the event detection device detecting the event. Furthermore, an object recognition system of the present disclosure detects an event by the event detection device under the control of the control section, acquires image information of a region including the event by the imaging device, and performs object recognition based on the acquired image information.
