Abstract

In a driving support display device 1 that includes a rear view wide angle camera 11, and an ECU 20 and a display 30 that display a rearward image captured by the rear view wide angle camera 11, a display control section 25 of the ECU 20 and the display 30 is capable of displaying a moving object approaching detection frame 210 that supports driving of a driver of a host vehicle 100 and a pedestrian detection frame 212 while dividing the rearward image into plural screens for display, and changes the number of the screens to be displayed between when the moving object approaching detection frame 210 is displayed and when the moving object approaching detection frame 210 is not displayed. Thus, the driver can easily recognize operation and non-operation of a system that displays the moving object approaching detection frame 210.
