A device to estimate visibility change of surroundings, including: an image recognition unit that detects a landmark by analyzing an image; an information storage unit that records, as a detection history in the past, an image analysis result of the landmark detected by the image recognition unit and a detection position when the landmark is detected by the image recognition unit; and a visibility judgment unit that estimates, when the landmark corresponding to the detection history recorded in the information storage unit is detected again by the image recognition unit, change in visibility on the basis of comparison between a detection position when detected again and the detection position in the past recorded in the information storage unit.
