Claim:
1. A dimming control device comprising: a transmittance changing part provided on a windshield of a vehicle and configured to change light transmittance of the windshield; a detector configured to detect a position of a contact operation on the windshield by a user; and a dimming control part configured to change the transmittance according to the position of the contact operation on a detection surface of the detector on condition that the detector has detected a contact operation at a control start region which is preset within the detection surface; wherein the detector includes a first end portion of the transmittance changing part in a part of the detection surface; wherein the control start region is set at the first end portion of the transmittance changing part; and wherein, when the user performs a slide operation from a first contact position, which is within the control start region, to a second contact position as the contact operation after the detector has detected the contact operation on the control start region, the dimming control part sets a region determined on the basis of the first end portion and the second contact position as a target region in which the transmittance is changed by the user.
