    • An electronic endoscope apparatus is provided that comprises an image-pickup device, an objective optical system, a compensation information storing memory, a mask data storing memory, and an electronic mask compensation processor. The objective optical system forms a subject image on an imaging surface of the image-pickup device. The compensation information storing memory stores compensation information which relates to a misalignment between an in-focus area produced by the objective optical system on the imaging surface, and an effective image sensing area of the image-pickup device. The mask data storing memory stores mask data for an electronic mask operation. The electronic mask compensation processor translates an electronic mask area in accordance with the compensation information.
    • 提供了一种电子内窥镜装置,其包括图像拾取装置,物镜光学系统,补偿信息存储存储器,掩模数据存储存储器和电子掩模补偿处理器。 物镜光学系统在图像拾取装置的成像表面上形成被摄体图像。 补偿信息存储存储器存储与成像表面上的物镜光学系统产生的对焦区域和图像拾取装置的有效图像感测区域之间的未对准相关的补偿信息。 掩模数据存储存储器存储用于电子掩模操作的掩模数据。 电子掩模补偿处理器根据补偿信息转换电子掩模区域。

    • In an organ-region-indication system incorporated in an electronic endoscope system in which an endoscope image is displayed as a motion image on a monitor in accordance with a video signal produced therein, an organ-region-image data base is formed based on an organ map. A plurality of reference data indicating organ-regions and a plurality of image data representing the organ-region are correspondingly stored in the data base. Still image data is retrieved as referential image data from the video signal at suitable regular time intervals. The data base is searched for image data which coincides with the referential image data after the retrieval of the still image data. Corresponding reference data is displayed on the monitor only when the image data, which coincides with the referential image data, is found by the searching.
    • 在其中根据其中产生的视频信号将内窥镜图像作为运动图像显示为监视器的电子内窥镜系统中的器官区域指示系统中,形成有机体区域图像数据库,其基于 器官图。 指示器官区域的多个参考数据和表示器官区域的多个图像数据相应地存储在数据库中。 静态图像数据以合适的规则时间间隔从视频信号中检索为参考图像数据。 在检索静止图像数据之后,搜索与参考图像数据一致的图像数据的数据库。 只有当通过搜索找到与参考图像数据一致的图像数据时,相应的参考数据才被显示在监视器上。
