    Abstract: A driving controller derives a first integrated value by integrating a first phase delay time of an output signal of a first angle detection sensor with respect to a first signal to be referred to corresponding to a first driving signal, the number of times that is greater by a factor of a natural number than the number of times corresponding to a period of time of one frame of a motion image to be drawn, and derives a second integrated value by integrating a second phase delay time of an output signal of a second angle detection sensor with respect to a second signal to be referred to corresponding to a second driving signal, the number of times that is greater by a factor of a natural number than the number of times corresponding to the period of time of one frame.

    Abstract: A driving controller provides a first driving signal having a first driving frequency to a first actuator, provides a second driving signal having a second driving frequency to a second actuator, derives a first average phase delay time by averaging a first phase delay time of an output signal of a first angle detection sensor with respect to the first driving signal in a plurality of cycles, derives a second average phase delay time by averaging a second phase delay time of an output signal of a second angle detection sensor with respect to the second driving signal in a plurality of cycles, generates a first reference signal based on the first driving signal and the first average phase delay time, and generates a second reference signal based on the second driving signal and the second average phase delay time.

    Abstract: There are provided an image exposure device, an image exposure method, and a program, the image exposure device including: an image display device; a support portion that supports a photosensitive recording medium for recording an image displayed on the image display device in a state in which an exposure surface thereof faces the image display device; a louver film that is provided between the image display device and the support portion and limits an angle of light radiated from the image display device; an image generation unit that generates a display image in which an image quality of a color input image is deteriorated by emphasizing a density difference of a high-frequency component of the input image; and a controller that performs a control for generating an image of an R component, an image of a G component, and an image of a B component from the display image and sequentially displaying each of the image of the R component, the image of the G component, and the image of the B component on the image display device in a predetermined order to sequentially expose the photosensitive recording medium.
