  • Patent number: 9900567
    Abstract: An image display device includes a light source, a screen, an optical system, a screen driving mechanism unit, a memory unit, and a screen driving circuit unit. An image is formed on the screen by being irradiated with light from the light source. The screen driving mechanism unit moves the screen in an optical axis direction of the light. A smoothed movement profile is obtained by smoothing a movement profile used as a target for moving the screen so as to make a moving speed of the screen vary gently. The memory unit stores screen driving waveform information that has been generated so that the screen follows the smoothed movement profile. The screen driving circuit unit drives the screen driving mechanism unit, based on the screen driving waveform information stored in the memory unit.

  • Patent number: 9520813
    Abstract: An actuator drive device is configured to drive an actuator. The actuator drive device includes a storage section for storing a drive condition of the actuator, a processor for calculating and outputting drive signal D(t) based on a drive base signal V(t) calculated based on the drive condition with respect to time t, and a generator for outputting, based on the drive signal D(t) calculated, a driving signal for driving the actuator. The drive base signal V(t) is a sum of a fundamental wave and at least one harmonic wave of the fundamental wave. The processor is operable to determine the coefficient ak such that the drive base signal V(t) changes linearly from a minimum value to a maximum value with respect to a time. This actuator drive device improves the linearity of the driving of the actuator.
