Abstract

A control unit ( 10 ) is a device for detecting the condition of a floor surface (FL) on which a target ( 30 ) has been placed, and comprises a distance calculation unit ( 11 ) and a target detection unit ( 18 ). The distance calculation unit ( 11 ) calculates information about the distance to the target ( 30 ) according to the amount of reflection of the light emitted from a lighting device ( 21 ) toward the target ( 30 ). The target detection unit ( 18 ) detects the condition of a floor surface (FL) on which the target ( 30 ) has been placed, on the basis of the information about the distance acquired by the distance calculation unit ( 11 ).
