A sign recognition and display device (1) includes: a camera (2); a sign recognition unit (10) configured to recognize a road sign included in an image taken with the camera; a speed limit information obtaining unit (12) configured to repeatedly obtain speed limit information; and a display control unit (14) configured to, if a speed limit sign is recognized, and the speed limit information is obtained, show, on a display device (8), information on a speed limit indicated by the speed limit sign. If, while information on the speed limit indicated by the speed limit sign is displayed, the speed limit information is obtained, and the speed limit determined by the obtained speed limit information is different from the speed limit determined by the previously obtained speed limit information, the display control unit shows information on the speed limit determined by the presently obtained speed limit information.
