Zusammenfassung:A scanning type image display apparatus including a light source, a frame buffer, a scanning mirror, a drive controller which outputs a drive signal to the scanning mirror, and a display controller which reads out pixel data from the frame buffer, generates display data for modulating an intensity of a laser beam using the readout pixel data, and causes the light source to emit an intensity-modulated laser beam based on the display data. The display controller calculates a scanning position of the laser beam on the display screen by the scanning mirror based on information relating to the drive signal inputted from the drive controller, reads out pixel data corresponding to the calculated scanning position on the display screen by executing a burst access to the frame buffer, and implements interpolation to generate the display data corresponding to the scanning position of the laser beam on the display screen.
