The present invention is provided with: a camera (10) mounted on a vehicle and provided with a lens (11); a lens cleaning device (100) for cleaning the lens in accordance with a predetermined leans cleaning process; an attachment state determination unit (38) for determining the attachment state including the attachment degree of foreign substances attached to the lens (11) on the basis of the pixel values of pixels contained in the acquired captured image; and a control unit (101) for controlling the supply timing of a cleaning solution on the basis of the determined attachment state of the foreign substances. The attachment state determination unit (38) determines that the attachment state of dirt on the lens (11) is a first state when the attachment degree of foreign substances is within a predetermined threshold value that is equal to or greater than a first attachment threshold value and that is less than a second attachment threshold value, and controls the lens cleaning device (100) to delay the supply timing of the cleaning solution when it was determined that the attachment state of dirt on the lens (11) is the first state.
