Patent ID: 8476569

Claim:
An image projection device which projects an image to a projection surface, said image projection device comprising: a light source section; a deflection section having a reflection part which reflects a light flux emitted from said light source section, and deflecting said light flux in a two-dimensional direction by rotation of said reflection part around a first axis and rotation of said reflection part around a second axis which is substantially perpendicular to said first axis; and a deflection control section which makes a control for rotating said reflection part around said second axis by resonance driving, and rotating said reflection part around said first axis by non-resonance driving, wherein said deflection control section controls the rotation of said reflection part around said second axis to thereby perform a distortion correction in one direction for suppressing an image distortion along one scanning direction on said projection surface, and controls the rotation of said reflection part around said first axis to thereby perform a speed correction in the other scanning direction for keeping substantially constant a scanning speed of said light flux along the other scanning direction which is substantially perpendicular to said one scanning direction on said projection surface, the relationship of 10°<θ<70° is satisfied, where θ represents an angle of inclination of said light flux, which is projected to said projection surface, toward said other scanning direction, relative to a normal line of said projection surface, in a case where said reflection part is in a central position of the rotations around said first and second axes.
