Patent ID: 8780096

Claim:
A scanning image display apparatus, comprising: a light source unit that emits a laser beam; a scanning mirror that two-dimensionally scans the laser beam in a first direction and in a second direction that crosses the first direction at predetermined scanning frequencies, respectively; a frame buffer that temporarily stores image data corresponding to images to be displayed on a display screen frame by frame; and a display controller that reads the image data from the frame buffer, generates display data used to modulate an intensity of the laser beam at a predetermined frame frequency using the read image data, and causes the light source unit to emit the laser beam intensity-modulated based on the display data, wherein the display controller controls the scanning frequencies in the first and second directions not to be in synchronization with the frame frequency, the frame buffer is so configured that the respective image data of a plurality of different frames can be temporarily stored therein and read therefrom, and the display controller reads the respective image data of the plurality of frames from the frame buffer and alternately switches the frames of the image data used for generation of the display data in synchronization with a scanning cycle of the scanning mirror.
