Abstract: A mirror driver drives deflection mirror surfaces into a pivoting action at a frequency belonging to a first drive frequency band in which the high-frequency side of a first resonance frequency band partially overlaps the low-frequency side of a second resonance frequency band, so that the deflection mirror surfaces deflect a light beam. Hence, the deflection angles of light beams change, while canceling out each other the changes of the deflection angles of the light beams deflected by the deflection mirror surfaces owing to changes of resonance characteristics. Because of this, even when the resonance characteristics change, it is possible to stabilize the deflection angle of the light beam deflected by the first deflection mirror surface and further deflected by the second deflection mirror surface.

Abstract: When a video display system displays an image having an aspect ratio that differs from the aspect ratio of the system's display monitor, the image spans only an “active” portion of the available display area on the monitor. The display system sets the luminance and/or chrominance of pixels in the inactive areas of the monitor to match the average luminance and/or chrominance of a selected group of pixels forming the image in the active area. This helps prevent ghosting by aging the phosphors or other material forming the pixels in the active and inactive areas at the same rate.
