摘要:
A scanning type image display apparatus includes a light source unit for emitting a laser beam, a scanning mirror for scanning the laser beam two-dimensionally in a first direction and a second direction that intersects the first direction, and a control unit for controlling driving of the scanning mirror. The control unit drives the scanning mirror such that a scanning frequency in the first direction is higher than a scanning frequency in the second direction, and varies a scanning amplitude in the first direction by varying the scanning frequency in the first direction in synchronization with a period of the scanning frequency in the second direction.
