A projector which displays an image by projecting a projection image onto a projection surface, includes: a fixed pixel display device for displaying the projection image in a predetermined vertical period; and an image processing device for generating the projection image in the vertical period, wherein the image processing device includes: a resolution converter which, by converting a resolution of an input image in the vertical period, generates and transmits a display image having a desired resolution; a projection distortion corrector which receives the display image, and generates the projection image by correcting the display image in the vertical period in such a way as to correct a projection distortion occurring due to a projection angle with respect to the projection surface when projecting the projection image; and a display image input/output controller which controls the reception of the display image from the resolution converter and the transmission thereof to the projection distortion corrector, wherein in the vertical period, the display image input/output controller holds the display image while receiving it from the resolution converter, during a time period from a predetermined timing prior to a start time of a process of correcting the display image by means of the projection distortion corrector to a finish time of the correction process, while it reads the display image held in advance, and transmits it to the projection distortion corrector, during a time period from the start time to the finish time of the correction process.
