Parking assist devices, methods, and programs

A parking assist device for a vehicle, comprising:

• a controller that:
• determines a current position of the vehicle;
• acquires image data from a camera provided on the vehicle;
• extracts a predetermined region of the acquired image data, the predetermined region being a portion of the image that will be in a blind spot of the camera if the vehicle travels a first predetermined distance from the current position;
• correlates the extracted image data with the current position of the vehicle;
• causes the correlated extracted image data to be stored in a memory;
• reads out past correlated extracted image data, the past correlated extracted image data having been acquired when the vehicle was in a previous position, the previous position being a second predetermined distance from the current position;
• and
• outputs a parking assist image to a display, the parking assist image displaying both the past correlated extracted image data, and the image data acquired at the current position of the vehicle.
