DIMMING GLASS CONTROL DEVICE AND DIMMING CONTROL SYSTEM

An objective of the present invention is to control a dimming glass while improving a user friendliness. A dimming glass control device 100 is configured for a dimming glass 11 including six dimming films arranged in different regions of a window glass 11a for a vehicle, wherein the dimming films have transmittances of light which are changed depending on application of an AC voltage, the dimming glass control device 100 comprising: a voltage applying section 110 configured to change the transmittances of the six dimming films respectively by application and non-application of the AC voltage to each of the dimming films; and a control section 120 configured to, in response to designation of one dimming pattern of five dimming patterns, control the voltage applying section 110 so as to apply the AC voltage to one or more of the six dimming films associated with the one dimming pattern which has been designated, wherein the dimming patterns differ from each other in at least one of a number of dimming films or a position of a dimming film in the dimming glass 11a to which the AC voltage is applied.
