摘要： A scanning image display includes a plurality of light sources adapted to emit a plurality of light beams, and a scan unit adapted to scan the light beams emitted from the light sources on a projection surface, which comprises a plurality of sub-illumination areas, in a first and second direction. One of the first and second directions is a high-speed scan direction and the other is a low-speed scan direction. The sub-illumination areas are arranged in the low-speed scan direction, such that the light beams scanned in adjacent sub-illumination areas are scanned in the opposite direction.

摘要： The present invention provides a rotation controller adjusting the speed of a rotary member (103). Phase difference compensating means (118) outputs a phase difference compensating signal (119) corresponding to a phase difference between a rotation signal of the rotary member (103) and a target signal, and frequency difference compensating means (114) outputs a frequency difference compensating signal (115) corresponding to a frequency difference between these signals. The rotary member (103) is braking-controlled by means of these signals. Use of the phase difference compensating signal (119) permits achievement of PLL control, and maintenance within the locking range allows a stable rotation control with a high response. Further, use of the frequency difference compensating signal (115) makes it possible to quickly bring the control within the locking range even when the rotary member (103) deviates from the target signal, and thus to carry out a control with a high response even upon riseup of the rotary member (103).
