1. A vehicle drive assist system comprising:
a processor programmed to:
capture an image of an area on a front side in a traveling direction of a vehicle;
determine a blind spot area, the blind spot area being an area that becomes a blind spot of a driver of the vehicle due to a front obstacle present on the front side in the traveling direction of the vehicle, the blind spot area being determined by:
setting a determination area, which is a predetermined area of a surface of a road intersecting a road on which the vehicle is traveling, a corner of the predetermined area being defined by a point on a surface of the road on which the vehicle is traveling and an edge portion of the front obstacle;
obtaining information of a first area, which is a road surface area of the road intersecting the road on that the vehicle is traveling within the determination area;
determining a second area, which is a road surface area of only a part of the road intersecting the road on which the vehicle is traveling that is visible within the captured image; and
calculating the blind spot area by subtracting the second area from the first area; and
display an alert image superimposed on a real view on a display by:
setting a size of the alert image based on the calculated blind spot area;
setting a target point at a point where traveling of the vehicle is likely to be influenced when there is a moving obstacle jumping out of the blind spot area; and
superimpose the alert image on the target point.
