    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 projector that can prevent laser light from entering eyes is provided. A process that controls the projector includes the steps of detecting turning-on of power to the projector; detecting an input for adjusting the reflection direction of a two-axis galvanometer mirror; sending an instruction to reduce output from respective lasers, to an FPGA; setting signal values of the lasers respectively controlled by laser control circuits, to small values; determining whether a certain period of time has elapsed since an operation input is no longer performed on an operation panel; standing by the process for a certain period of time when the certain period of time has not elapsed since an operation input is no longer performed; and returning the signal values to a normal level when the certain period of time has elapsed since an operation input is no longer performed.

    摘要: An image display apparatus is provided that allows a user to check image content even in a place where there is no projection screen. A projector that is one mode of the image display apparatus includes a casing, a projection aperture provided in the casing, and an internal projection mirror and a built-in screen that are provided in a casing. When the projector is being folded, laser light emitted from the projection aperture is reflected by the internal projection mirror. The reflected light is projected onto the built-in screen, whereby an image is displayed.
