摘要： An electronic endoscope system has a video-scope, an illumination apparatus, an imaging device, and an image synthesizing processor. The illumination apparatus illuminates a normal light and an excitation-light from the video-scope onto an object. The normal light is reflected off the object, and the excitation-light causes the object to emit fluorescence. The imaging device on the video-scope captures a normal image that is formed by the reflected normal light and a fluorescent image that is formed by the fluorescence. The image synthesizing processor synthesizes the normal image and the fluorescent image into a synthesized image. A color signal of the synthesized image is the same as a color signal of the normal image. A luminance signal or the synthesized image is obtained by mixing a luminance signal of the normal image and a luminance signal of the fluorescent image in a predetermined proportion.

摘要： In an electronic endoscope system, a scope has a solid-state image sensor provided at a distal end thereof to generate image-pixel signals. An image-signal processing unit produces a video signal based on the image-pixel signals. An alteration system alters a peak-to-peak level of a synchronizing-signal component of the video signal. An manual setting system operates the alteration system to perform the alteration of the level of the synchronizing-signal component. An indicator system indicates the degree of alteration to the level of the synchronizing-signal component during the operation of the manual setting system.

摘要： An image data processor comprising an image signal receiver, a histogram generator, a gain calculator, an amplifier, and a signal feeder, is provided. The image signal receiver receives an autofluorescence image signal. The autofluorescence image signal is generated by an imaging device when the imaging device captures an autofluorescence image. The histogram generator generates a histogram of luminance in the autofluorescence image based on the autofluorescence image signal. The gain calculator calculates a gain based on the histogram and a predetermined luminance value. The amplifier amplifies the autofluorescence image signal by the gain. And then the amplifier generates an amplified autofluorescence image signal. The signal feeder outputs the amplified autofluorescence image signal to a monitor. The monitor displays an amplified autofluorescence image.
