    • This invention provides a microscope for operation which can form a black point for protecting a patient's retina even when the retina part is not at the center of the field of view of the microscope. The microscope for operation has an X-Y stage for moving the microscope body, a CCD camera for obtaining an image in the field of view of the microscope, a liquid crystal device provided with a light transmitting surface transmitting illuminating light therethrough and comprised of display dots disposed in the form of a matrix, and a control device for controlling and driving the liquid crystal device. The control device analyzes the image in the field of view of the microscope obtained by the CCD camera to thereby recognize the position of the retina part of an eye to be examined, and the display dots positioned in that area on the light transmitting surface of the liquid crystal device which has been determined correspondingly to the recognized position are selectively colored to thereby constitute a black point filter.
    • 本发明提供了一种用于操作的显微镜,其可以形成用于保护患者的视网膜的黑点,即使视网膜部分不在显微镜的视场的中心。 用于操作的显微镜具有用于移动显微镜体的XY平台,用于获得显微镜视野中的图像的CCD照相机,具有透射照明光的透光表面的液晶装置,包括布置的显示点 以矩阵的形式,以及用于控制和驱动液晶装置的控制装置。 控制装置分析由CCD照相机获得的显微镜的视野中的图像,从而识别被检眼的视网膜部分的位置,并且位于该被检眼的透光表面上的该区域中的显示点 已经对应于识别的位置确定的液晶装置被选择性地着色,从而构成黑点滤光器。

    • An electronic device includes a carriage on which an image sensor is mounted, a motor that drives the carriage, and servo-control-containing printed matter provided in one or more detection areas of the image sensor or one or more independently provided optical sensors. The servo control information is used for speed control and initial position detection of the carriage. A servo controller performs the servo control on the motor via a motor driver based on the read servo control information. The printed matter is provided on a rear or underside surface of a support structure in areas irradiated by a light source for the image sensor. Printed matter for speed control may be provided in one area and printed matter for initial position detection in another. Servo control information on the printed matter may be read using a dummy pixel region of the image sensor.
    • 一种电子设备包括:安装有图像传感器的托架,驱动托架的马达和设置在图像传感器的一个或多个检测区域中的伺服控制的打印物,或者一个或多个独立设置的光学传感器。 伺服控制信息用于车架的速度控制和初始位置检测。 伺服控制器基于读取的伺服控制信息经由马达驱动器对马达进行伺服控制。 印刷物在由图像传感器的光源照射的区域中设置在支撑结构的后表面或下表面上。 用于速度控制的印刷品可以在一个区域中提供,并且可以在另一个区域中提供用于初始位置检测的印刷品。 可以使用图像传感器的虚拟像素区域来读取关于印刷物的伺服控制信息。
