    • Provided is a spatial image display device capable of forming spatial images having a superior reality and high definition. A spatial image display device 10A is provided with: a display section 2 including a plurality of pixels 22, and generating a two-dimensional display image corresponding to a video signal; a first lens array 1 including a plurality of first lenses 11 provided in correspondence with the respective pixels 22, and allowing light passing through the respective pixels 22 to converge; and a second lens array 3 converting the converging light, which has passed through the first lens array 1, into parallel light or converging light, and allowing the converted light to pass therethrough. The light transmitting through the respective pixels 22 in the display section 2 is directed to the second lens array 3 after being converged by the first lens array 1. Accordingly, the light entering the second lens array 3 from the respective pixels 22 behaves like light emitted from a point source, and is converted easily into the parallel light or the converting light in the second lens array 3.

    • A focus control apparatus conducts a focus control with respect to an imaging apparatus configured to vary the focal point using a deformable mirror. An imaging unit first obtains image data via imaging elements and imaging optics provided in the imaging apparatus. A controller controls the driving of the deformable mirror such that, during a first image reading period wherein the reading of an image signal is periodically executed by means of the imaging elements, a focus drive state is achieved whereby an in-focus point that has been found in advance is set as the current focal point. During a second image reading period different from the first image reading period, the deformable mirror is controlled so as to achieve a focus drive state for in-focus point search.
    • 聚焦控制装置对配置为使用可变形反射镜改变焦点的成像装置进行聚焦控制。 成像单元首先通过成像装置中提供的成像元件和成像光学元件获得图像数据。 控制器控制可变形反射镜的驱动,使得在通过成像元件周期性地执行图像信号的读取的第一图像读取周期期间,实现聚焦驱动状态,从而获得已经被聚焦的对焦点 事先设定为现在的焦点。 在与第一图像读取周期不同的第二图像读取周期期间,控制可变形反射镜以便实现聚焦驱动状态用于对焦点搜索。
