Claim 2:
3. 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 adjustment circuit
performs overdrive processing of determining, based on a gradation indicated by the image signal, a compensation amount for compensating the response velocity, and
adjusts, based on the order in which the image signals are supplied, for each of the plurality of pixels, the compensation amount determined through the overdriving processing to generate the image signal based on the compensation amount after the adjustment,
the plurality of pixels include a first pixel and a second pixel, the first pixel being supplied with the image signals in a first half of the order, the second pixel being supplied with the image signals in a second half of the order,
the unit period includes a first period and a second period subsequent to the first period,
the adjustment circuit
makes the compensation amount used to generate the image signal supplied to the first pixel in the first period smaller than the compensation amount determined through the overdrive processing, and
makes the compensation amount used to generate the image signal supplied to the second pixel in the first period larger than the compensation amount determined through the overdrive processing, and
the adjustment circuit does not change the compensation amount used to generate the image signals supplied to the first pixel in the second period and the compensation amount used to generate the image signals supplied to the second pixel in the second period, from the compensation amount determined through the overdrive processing.
