Summary:An advantage of some aspects of the invention is to allow that improving of the brightness of image viewed through 3D glasses by a user and suppressing of the increase of lamp drive power used as a projection light source in the projector are compatible when a 3D picture is displayed by the projector. A projector (10) includes a lamp (2102) that emits projection light to project 3D picture, in which a right eye image and a left eye image are represented in a time division manner, to an object; a synchronization signal transmission section (15, 16) which transmits shutter synchronization signal to glasses (20) having a right eye shutter and a left eye shutter to control the opened state or the closed state of the right eye shutter and the left eye shutter, based on the signal indicating a displaying period of the right eye image and the left eye image of 3D picture; and a lamp drive section (13) that supplies AC current having peak overlapping with a period when the right eye shutter of the glasses is in the o
