摘要： In a method for driving a micro mirror such as MEMS mirror and a display apparatus using the method, there are provided a mirror driving unit for driving the micro mirror which operates in a resonant mode and a nonresonant mode, a driving-condition setting unit for setting a mirror driving condition, a switching unit for switching on/off a mirror driving signal in the nonresonant mode, and a look-up table for indicating the relationship of a mirror response with respect to the driving condition already known in advance. The switching unit controls the transmission of the nonresonant-mode mirror driving signal while grasping the mirror response state with respect to the mirror driving signal, thereby finely increasing and decreasing a driving torque for the micro mirror. This fine increase and decrease allows the micro mirror to be fluctuated stably, and a further enhancement in the fluctuation rate.

摘要： For enabling to prevent ill effects from being generated in the structures of a reflection mirror, even if increasing an output energy from a light source, thereby preventing ill influences from being exerted on the driving condition thereof, a mirror drive controller unit 7 reads out history data of the past, relating to temperature changes on a micro mirror 1, from a first LUT holder unit 19. Upon basis of the read-out history data of the past is presumed the temperature on the micro mirror 1 at the present time. The presumed temperature on the micro mirror 1 is temperature P temp of the micro mirror 1 at the present time, and upon that P temp are changed vibration (or oscillation) condition of the micro mirror 1 in the horizontal (H) direction and vibration (or oscillation) condition thereof in the vertical (V) direction.

摘要： A display apparatus is provided which, when projecting a video onto a curved surface of an object for display, can realize an undistorted display of the video. The measuring means outputs the distance information representing the distance to the object. Based on the distance information produced by the measuring means, the curved surface contour is detected with high precision. According to at least the detected curved surface contour distortions, pixels of the display image are unevenly rearranged to correct the video information before it is output. This arrangement realizes an undistorted display of video when the video is projected onto the curved surface of the object.
