1. A projector comprising:
an electro-optical panel including a plurality of pixels;
an optical-path shift element configured to change an optical path of light emitted from the plurality of pixels; and
an image processing circuit configured to supply image signals to the plurality of pixels in a predetermined order in a unit period included in one frame period for displaying one frame of an image indicated by an input image signal, the image signals being generated in response to the input image signal and corresponding to the plurality of pixels, wherein
the image processing circuit includes an adjustment circuit configured to adjust a response velocity of the plurality of pixels at a time of switching the image displayed by the electro-optical panel, based on the order in which the image signals are supplied or positions of the plurality of pixels at the electro-optical panel,
the plurality of pixels include a first pixel and a second pixel, the first pixel being supplied with the image signal in a first half of the order, the second pixel being supplied with the image signal in a second half of the order,
the one frame period includes a first unit period and a second unit period subsequent to the first unit period, and
in the second unit period, the adjustment circuit
corrects a gradation value of the image signal to be supplied to the first pixel to reduce a difference between a gradation value of the image signal to be supplied to the first pixel in the second unit period and a gradation value of the image signal supplied to the first pixel in the first unit period, and
corrects a gradation value of the image signal to be supplied to the second pixel to increase a difference between a gradation value of the image signal to be supplied to the second pixel in the second unit period and a gradation value of the image signal supplied to the second pixel in the first unit period.
