    • An optical observation apparatus includes: an optical system which produces an image of an object being observed and a video device (7) for recording the image and producing an image signal. The video device (7) includes a first memory (71) for temporarily storing the image signal, a second memory (73) in data communication (77) with the first memory (71), and a control device (75) in communication (76A, 76B) with both memories (71, 73) for controlling the storage procedure in the first memory and data transfer from the first to the second memory. The control device (75) controls the storage procedure and the data transfer so that overwriting of such data already stored for a given period of time in the first memory (71) is effected and that transfer of the content of the first memory (71) to the second memory (73) takes place as a reaction to a trigger signal.
    • 光学观察装置包括:产生被观察物体的图像的光学系统和用于记录图像并产生图像信号的视频装置(7)。 视频设备(7)包括用于临时存储图像信号的第一存储器(71),与第一存储器(71)进行数据通信(77)的第二存储器(73)和通信中的控制设备(75) 76A,76B),具有用于控制第一存储器中的存储过程的两个存储器(71,73)和从第一存储器到第二存储器的数据传送。 控制装置(75)控制存储过程和数据传送,使得已经在第一存储器(71)中已经存储了一段给定时间段的数据的重写被实现,并且第一存储器(71)的内容的传送 发生到第二存储器(73)作为对触发信号的反应。
