In order to estimate changes in ambient visibility, this visibility estimation device is provided with: an image recognition unit (1) that detects landmarks by analyzing images; an information storage unit that records, as past detection history, image analysis results for the landmarks detected by the image recognition unit (1), and the detection positions when the image recognition unit (1) detects the landmarks; and a visibility determination unit (3) that estimates a change in visibility on the basis of comparisons between past detection positions recorded in the information storage unit (2) and the detection positions when the image recognition unit (1) redetects landmarks corresponding to the detection history recorded in the information storage unit (2).
