    • An image display apparatus has a correction unit that performs a correction process on image signals so as to suppress luminance fluctuation caused by capacitive coupling between adjacent column wirings. The correction unit includes: a correction value generation unit that determines a correction value for a pixel to be corrected on the basis of a combination of a signal value of the pixel to be corrected and signal values of adjacent pixels which are on a column wiring next to a column wiring on which the pixel to be corrected is, and on the basis of a position of the pixel to be corrected in a column direction; and a correction operation unit that corrects a signal of the pixel to be corrected using the correction value generated by the correction value generation unit.

    • An optical object measurement apparatus includes a light source for generating a low-coherent light beam, which is swept via an array of pinholes on a Nipkow disk that rotates about an axis. A beam splitter splits the swept light beam into a probe light beam toward an object to be measured and a reference light beam toward a reference optical path. The probe light beam from the object and the reference light that has traveled along the reference optical path are combined in the beam splitter to produce interference light. A two-dimensional image-capturing device detects the interference light and produces a video signal to provide reflection intensity information of the interior of the object. This allows an interference optical system to be readily realized and tomographic images of an object to be observed at high levels of resolution and contrast.
    • 光学物体测量装置包括用于产生低相干光束的光源,该光束通过在围绕轴线旋转的Nipkow盘上的针孔阵列扫过。 分束器将扫掠光束分成探针光束朝向被测量物体,并将参考光束朝向基准光路分开。 来自物体的探测光束和沿着参考光路行进的参考光被组合在分束器中以产生干涉光。 二维图像捕获装置检测干涉光并产生视频信号以提供物体内部的反射强度信息。 这允许容易实现干涉光学系统并且以高水平的分辨率和对比度来观察待观察对象的断层图像。
