    • An imaging system for use with an endoscope, including a light source which emits white light and excitation light which will produce a fluorescence response by an object under inspection, an imaging camera including separate paths for processing images produced by white light and excitation light, a selection device that causes the imaging device to operate in a white light mode or an excitation light mode, and a protective device that prevents damage to high-sensitivity imaging components from exposure to excessive light input. Fluorescent image data are separated into at least red and green color bands which are separately processed to produced a video display in which normal tissue is displayed in predetermined specific color, and abnormal tissue in one or more distinctly different colors. In one embodiment, an image color interpretation guide is provided in the form of multiple color bars which are superimposed on a single video display device with the image display. of different kinds. In another embodiment, color control is provided by adjusting the amplification of the imaging components for each of the color bands while viewing tissue known to be normal using a recursive algorithm until the ratio of the maximum values of the color separation signals fall within a predetermined range. The high-sensitivity imaging components are protected by controlling impingement of light on the imagining components, selectively controlling emission of white and excitation light from the light source, and controlling the power source for the imaging components.
    • 一种与内窥镜一起使用的成像系统,包括发出白光的光源和由被检查物体产生荧光响应的激发光,包括用于处理由白光和激发光产生的图像的分离路径的成像摄像机, 选择装置,其使得成像装置在白光模式或激发光模式下操作;以及保护装置,其防止对高灵敏度成像部件的损害暴露于过度的光输入。 荧光图像数据被分成至少红色和绿色色带,其分开处理以产生其中以预定特定颜色显示正常组织的视频显示,以及以一种或多种明显不同的颜色显示异常组织。 在一个实施例中,以多个彩条的形式提供图像颜色解释指南,所述多个彩条叠加在具有图像显示的单个视频显示装置上。 不同种类。 在另一个实施例中,通过调整每个色带的成像部件的放大率来提供颜色控制,同时使用递归算法观察已知为正常的组织,直到颜色分离信号的最大值的比率落在预定范围内 。 高灵敏度成像组件通过控制对想像组件的光的照射来保护,选择性地控制来自光源的白光和激发光的发射,以及控制成像组件的电源。
