摘要： A deviation of an optic axis of a laser projector is detected, and the deviation is corrected. Laser projector's CPU executes: commanding a laser beam source of one color, out of laser beam sources of three colors, to emit a laser beam; shutting off the laser when sensing that the laser beam is received in a light-receiving region; applying a laser of a color to be detected as to the presence or absence of a deviation of the axis until its reception in the light-receiving region is sensed; keeping time starting when light reception in the light-receiving region is sensed and ending when light reception in a light-receiving region adjacent thereto is sensed; calculating a relative time difference of each of the colors with respect to a reference color; and correcting a light emission timing of the laser beam source of each of the color, based on the calculated time.

摘要： A detection surface of an optical detector is divided into regions C, E, F, G, and H. The optical detector outputs detection signals corresponding to the amounts of light incident on the respective regions. A position detection controller calculates an image projection position based on timing at which a laser beam is incident on region C. A laser control circuit adjusts the intensity of the laser beam emitted by a laser based on laser beam intensities detected in regions E to H arranged around region C.

摘要： An image display apparatus wherein reduction in contrast or resolution is prevented is provided. A laser projector as an embodiment of the image display apparatus includes a memory storing a threshold value predetermined for changing a driving mode of a laser light source, a calculator for calculating an optical power level for projecting an image, a driving-mode selector selecting a mode for driving the laser light source, a driving controller for sending a signal to the laser light source in accordance with a selected driving mode, and a laser emitter. The laser projector operates at least at a bias current value Ib or more. In this case, when the optical power level is lower than or equal to a predetermined threshold value TH, the laser projector emits pulsed light. When the optical power level based on a video signal exceeds threshold value TH, the laser projector changes the driving mode of laser light emission from pulsed light emission to DC light emission, to supply a current higher than or equal to bias current value Ib to each laser light source.
