摘要： An image display device is provided, by which variations in drive sensitivity of a scan mirror is corrected. Processing executed by a CPU in a laser projector includes the steps of: driving a scanner mirror in a vertical direction; allowing at least one of a green laser and red/blue lasers to emit light; calculating stay time in a light-receiving region in a photoreceptor; comparing the calculated stay time with ideal stay time Tideal; decreasing a tilt of a drive signal for driving the scanner mirror in the vertical direction if the calculated stay time is shorter than the stay time Tideal; and increasing the tilt of the drive signal if the calculated stay time is longer than the stay time Tideal.

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.
