Abstract
An object approach detection device includes: an imager that includes a first and a second lens group which have different focal lengths from each other and are arranged so as to image a same target object and that acquires first and second image information imaged through the first and the second lens group, respectively; an object detector that detects presence or absence of an object; and an object approach determiner that determines that approach of the object has been detected when a time difference between a first time and a second time is equal to or less than an approach determination threshold value, the first time being when the first image information is acquired when the object has been detected based on the first image information, the second time being when the second image information is acquired when the object has been detected based on the second image information.
