A surrounding image display system (1, 2) equipped for a vehicle includes a processing unit (10, 12) that is connected to a camera (20, 22) that captures an image around the vehicle. The processing unit (10, 12) processes the captured image from the camera (20, 22) to recognize an attention object, and generates a display image in which a frame border (70) that at least partially surrounds the recognized attention object is superimposed on the captured image. The frame border (70) includes a first frame border portion (72) drawn in a first color and a second frame border portion (74) drawn in a second color different from the first color.
