Claims (9)

An image projecting unit; an image providing unit that provides a projection image to the image projecting unit; a blur movement detecting unit that detects a blur movement of the image projecting unit; and the image providing unit based on detection by the blur movement detecting unit. A projector comprising: an image processing unit configured to perform image processing for correcting trapezoidal distortion caused by blurring on a provided projection image. The image processing unit corrects the trapezoidal distortion caused by the blur for the projection image provided by the image providing unit when a blur component in a direction causing the trapezoidal distortion is included in the blur detected by the blur movement detection unit. The projector according to claim 1, wherein image processing is performed. 3. The projector according to claim 2, wherein the image processing unit shifts a projection image provided by the image providing unit in a direction in which the image processing unit corrects the image based on detection by the blur movement detection unit. It has a position detector, the image processing unit, the projector according to any one of claims 1 to 3, characterized in that changes the correction of the trapezoidal distortion caused by the camera shake based on the detection of the position detector . The projector according to claim 4 , wherein the image processing unit reverses the correction of the trapezoidal distortion caused by the blur based on the detection of the posture detection unit. Wherein the image processing unit, one of claims 1 to 5, characterized in that relative to the projection image by the image providing unit based on the detection of the blur movement detection unit is provided to change the reduction ratio of the longer side of the trapezoidal distortion A projector according to the above. An image projecting unit, an image providing unit that provides a projection image to the image projecting unit, a blur movement detecting unit that detects a blur movement of the image projecting unit, and a direction for correcting the blur based on the detection of the blur moving detector The projector further includes: an image processing unit that shifts the projection image provided by the image providing unit and performs image processing for correcting trapezoidal distortion of the projection image caused by blur in conjunction with the shift. Both the attitude detection unit, claims 1 to tilt said attitude sensor is detected, characterized in that a control unit not to perform the trapezoidal distortion correction by the image processing unit when the given below 7 A projector according to the above. The projector according to claim 1 , wherein the image processing unit synthesizes a supplementary image with a projection image provided by the image providing unit based on detection by the blur movement detection unit.
