Camera system, event recording system and event recording method

A method of recording an event by using a camera system mountable on a vehicle, the method comprising the steps of:

• capturing multiple frame images of an outside of the vehicle in a given cycle with an imaging unit;
• obtaining the multiple frame images from the imaging unit to be processed in an image processor;
• separating the multiple frame images in the image processor into a first given number of frame images as a recognition target and a second given number of frame images as a storage target to be stored in an image recorder;
• separately outputting the first and second given numbers of frame images to be recognized and stored, respectively, from the image processor;
• receiving the first and second given numbers of frame images in a vehicle controller;
• performing recognition of the frame image of the recognition target;
• controlling the vehicle in accordance with a result of the recognition;
• either detecting an event related to a behavior of own vehicle with the sensor or receiving a notification of an event occurring on the other vehicle related to a behavior of the other vehicle from the external equipment;
• communicating with an external equipment and obtaining external data from the external equipment via a communicator,
• the external data including at least one of pre-event data and post event data, the pre-event data representing phenomena existing prior to occurrence of the event, the post event data representing phenomena existing after occurrence of the event;
• and
• making a record of the events, the frame images of the storage target, and the external data in the recorder while associating the events, the frame images of the storage target, and the external data with each other.
