Abstract:
A projector including: a display unit equipped with an image-forming surface made up of a plurality of pixels; a projection lens that is capable of focus adjustment and that projects an image that is formed on the image-forming surface onto a projection surface; a distortion correction processing unit that, on the basis of distortion correction data for correcting distortion of an image projected onto the projection surface, generates a corrected image by enlarging and/or reducing an image indicated by an input video signal and forms the corrected image on the image-forming surface; and a control unit that adjusts the focus of the projection lens on the basis of the distortion correction data such that a focus range on the projection surface is increased.

Claim (Index 5):
The projector as set forth in  claim 2 , further comprising:\n a combining unit that generates a combined image in which an image for focus adjustment is combined with said corrected image and causes the combined image to form on said image-forming surface; wherein said projection lens includes: a focus lens; and an operation unit that accepts operation for focus adjustment, causes said focus lens to move along the optical axis according to the operation, and supplies an operation signal that indicates the direction of movement and the amount of movement; and said control unit: takes a region of pixels having the smallest correction coefficient value as a nearest focus point, takes a region of pixels having the largest correction coefficient values as a farthest focus point, and causes the combining unit to generate a first combined image in which a first image that indicates said nearest focus point is combined as said image for focus adjustment with said corrected image and a second combined image in which a second image that indicates said farthest focus point is combined as said image for focus adjustment with said corrected image; when the user operates said operation unit to carry out focus adjustment for said first image on the projected image of said first combined image, acquires first positional information that indicates a position on said optical axis of said focus lens when focus is realized at said nearest focus point based on said operation signal; when the user operates said operation unit to carry out focus adjustment for said second image on the projected image of said second combined image, acquires second positional information that indicates a position on said optical axis of said focus lens when focus is realized at said farthest focus point based on said operation signal; and based on the relation of said correction coefficient values of said nearest focus point, farthest focus point and optimal point and said first and second positional information, acquires a position on said optical axis of said focus lens when focus is realized at said optimal point and causes said focus lens to move to the position.
