1. A projector comprising:
an electro-optical panel in which a plurality of pixels are arrayed;
an optical path shifting element configured to change an optical path of light emitted from the plurality of pixels;
an image processing circuit configured to supply a first image signal based on an input image signal to the electro-optical panel in a first unit period among a plurality of unit periods included in one frame period and supply a second image signal based on the input image signal to the electro-optical panel in a second unit period after the first unit period among the plurality of unit periods; and
a control circuit configured to control a state of the optical path shifting element such that light emitted from a predetermined pixel among the plurality of pixels reaches a first position on a display screen in the first unit period, control a state of the optical path shifting element such that light emitted from the predetermined pixel reaches a second position on the display screen in the second unit period, and control, based on a type of image indicated by the input image signal, a state of the optical path shifting element in a transition period in which a unit period transitions from the first unit period to the second unit period, wherein
the control circuit controls a state of the optical path shifting element such that light emitted from the predetermined pixel reaches a third position on the display screen in the transition period, and
the image processing circuit generates a third image signal to be supplied to the electro-optical panel based on the first image signal and the second image signal in the transition period.
