SCANNING LIGHT MEASUREMENT APPARATUS, IMAGE DISPLAY CONTROLLER AND METHOD OF CONTROLLING IMAGE DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a scanning light measurement apparatus which measures scanning light for allowing the horizontal scanning direction and the vertical scanning direction of image light to accurately intersect at a right angle so that a good quality of an image is given in an image display such as a retina scanning display, and accurately obtains the relation of positions of two scanning directions in a two-dimensional scanning system; to provide an image display controller which controls the display of the image by measuring the scanning light, and to provide a method of controlling the image display. SOLUTION: An imaging part 6 images the beam MB scanned with either a first scanning part 4 or a second scanning part 5. The tilt of the beam BM scanned in the first direction with the first scanning part 4 and the tilt of the beam BM scanned in the second direction with the second scanning part 5 are calculated. The angle between the first direction and the second direction in an imaging region 1A is calculated from the calculated tilts. COPYRIGHT: (C)2011,JPO&INPIT
