Patent ID: 8894217

Claim:
An image projection apparatus, comprising: a light source; a projected image outputting unit having multiple mirrors arranged in a matrix pattern, to which radiating light emitted from the light source is directed while controlling an angle of a light reflection face of each of the mirrors; a control unit having a processing circuit, to control the angle of the light reflection face of each of the mirrors of the projected image outputting unit using time division half-toning control based on image data of an image projected by the projected image outputting unit and control parameters used for the time division half-toning control; and an image capturing device to capture the image projected by the projected image outputting unit, wherein the control unit instructs the projected image outputting unit to project a test pattern image for image adjustment, wherein when the control unit detects a false contour in the test pattern image based on image data of the projected test pattern image captured by the image capturing device, the control unit corrects the control parameters for the time division half-toning control based on detection of the false contour to suppress occurrence of the false contour, wherein when the false contour is detected, the control unit instructs the projected image outputting unit to project an image by enlarging a portion of the false contour.
