    摘要: An endoscope apparatus, comprising an imaging controller, a receiver, and an image generator, is provided. The imaging controller makes an optical image to be captured so that the amount of optical information to be captured per a certain area size for an enlarged observation area is greater than that for a normal observation area. The receiver receives the optical information as a pixel signal. The image generator generates a normal image signal corresponding to a normal image on the basis of the pixel signals captured within the normal observation area and a part of the pixel signals captured within the enlarged observation area. The image generator generates an enlarged image signal corresponding to an enlarged image on the basis of the pixel signals captured within the enlarged observation area.

    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-signal processing unit comprising a first and second luminance calculation block, a correction-value calculation block, and a subtraction block, is provided. The first luminance calculation block calculates a first luminance corresponding to the sum of a plurality of primary color light components. Each of them is multiplied by a coefficient from a first coefficient combination. The second luminance calculation block calculates a second luminance corresponding to the sum of a plurality of the primary color light components. Each of them is multiplied by a coefficient from a second coefficient combination. The correction-value calculation block calculates a luminance correction value according to the second luminance if the first luminance is greater than a threshold value. The subtraction block calculates a corrected luminance by subtracting the luminance correction value from the first luminance.

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.
