Claim:
A parking assist system, comprising: a display unit; and a controller that: identifies a position of a vehicle; obtains image data of an area around the vehicle from a camera on the vehicle; associates the obtained image data with a position of the vehicle where the image data was obtained; stores the obtained image data and the associated position of the vehicle as past image data in a memory; determines whether the vehicle is moving backward, wherein the determination of whether the vehicle is moving backwards is based on a determined movement direction of the vehicle; calculates a backward movement distance from a backward movement start position; determines whether the calculated backward movement distance is larger than a predetermined distance; determines a steering angle of the vehicle and whether the steering angle is less than a predetermined angle; and displays an image on the display unit when it is determined that a parking operation has gone onto a latter half of the parking operation based on a determination that the vehicle is moving backward, the backward movement distance is larger than the predetermined distance and the steering angle is less than the predetermined angle, the displayed image being based on the past image data and image data taken at a current position of the vehicle.
