A method corrects trapezoid distortion of projected images using a projector. The projector includes a projection lens, a driver device, an image capturing device, and a storage system. A rectangular picture is read from the storage system and projected on a projection area by the projection lens. The method controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid row correction grade, and corrects each trapezoid row of the captured image if the captured image has trapezoid rows. The method further controls the image capturing device to capture an image from the projection area when the projection lens increases one trapezoid column correction grade, and corrects each trapezoid column of the captured image if the captured image has trapezoid columns. |
