To provide a display controller which can make a display device indicate an image in which a distance between an obstacle and a vehicle is easy to recognize without operation burden to a user.
The display controller with an image conversion means carries out image conversion of an imaging video image photographed by a camera 2 which photographs external of a vehicle to an looking-down video image which looks an photographing range of the camera 2 from a virtual eye point 36 and by a virtual eye line 38. The image conversion means decides a point of the virtual eye point 36 in a position in which the eye point of the imaging device is moved in a height direction 37 of the vehicle, so that a length of a perpendicular line 35 drawn from the virtual eye point 36 to an intersection line 34 of a second plane 32, which is in parallel with a first plane 30 contacting with an end face in which the camera 2 of the vehicle is prepared and contacting with a vehicle side of an obstacle 31, and a horizontal virtual road face 33 for the vehicle becomes a constant value. It decides a depression angle 39 of the virtual eye line 38 so that the virtual eye line 38 agrees to the perpendicular line 35.
