摘要： The apparatus according to the present invention includes a level adjusting circuit that increases a gain of a G (or B) signal output from a color conversion circuit, a binarization circuit that forms a binarized image from this G signal and an edge detection circuit that extracts blood vessel position signals through edge detection based on this binarized signal. Then, the apparatus extracts RGB color signals making up a blood vessel image by using the above-described blood vessel position signals, increases the gains of these blood vessel color signals and then adds the blood vessel color signals to the color signals of an original image. This allows blood vessels to be displayed in high contrast to mucous membranes, etc. Furthermore, the apparatus can also amplify the R signal and B signal by using a signal obtained by differentiating the above-described G signal as a gain signal to highlight blood vessels.

摘要： In an electronic endoscope of the present invention, an edge detection circuit detects a down edge section and an up edge section of both ends of a blood vessel in a width direction based on a G signal output from an RGB color conversion circuit, an R coefficient selector and a B coefficient selector select, for example, a coefficient smaller than 1 for the detected down edge section and select, for example, a coefficient larger than 1 for the up edge section, and a multiplier multiplies an R signal and a B signal by these coefficients. As a result, both ends of the blood vessel are highlighted with a left end part expressed blackish and a right end part expressed reddish, making it possible to clearly display blood vessels in mucous membranes on a monitor. It is also possible to detect phases on a coordinate system where an R-Y signal is set on a vertical axis and a B-Y signal is set on a horizontal axis, compare these phases with reference phase θ1 of blood vessel colors and extract signals of blood vessel colors.

摘要： An endoscope includes a red component cut optical filter having a characteristic that a spectral transmittance becomes half at 630 nm and zero at 670 nm, for example between a light source and an infrared cut filter, to remove a long wavelength component mainly in a red band of illumination light. This restrains scattering of light on a long wavelength side of red light, and allows taking images of mucosa, blood vessels, and other tissue in good contrast in an object to be observed and satisfactorily observing them on a monitor. Further, reduction in light amount resulting from cutting a red component with the filter is eliminated by light amount control with an aperture and gain control of a signal.

摘要： The invention provides an endoscope having a scope that takes an image enlarged by driving a movable lens of an optical zoom mechanism by a CCD and displays an image of an object to be observed, wherein a multiplier multiplies RGB color signals by a coefficient set in view of light distribution of illumination light depending on focusing distances of the movable lens, thus eliminating uneven brightness resulting from varying light distribution depending on the focusing distances in enlargement photography. A red component cut filter for cutting a long wavelength side in a red band of the illumination light is provided in a light source unit to improve redness. Further, a coefficient for averaging a brightness signal for a predetermined number of pixels for each horizontal line is calculated, and this coefficient calculation may eliminate unevenness.

摘要： The present invention is a unit for eliminating the fluctuation of luminous energy reduction by keeping the response time of a shading mechanism constant even if a diaphragm opening degree differs when reading every pixel by setting a shading period. This unit is provided with a shading mask having a quadrangular or V-shaped opening and moves a shading shutter in the horizontal direction perpendicular to the vertically moving direction of a diaphragm plate. Therefore, a shading period is set in accordance with the constant response time of the shading shutter and the rate of luminous energy reduction becomes constant. Moreover, a high-quality static image having a stable brightness can be obtained by reading the signal of every pixel obtained by a CCD through one-time exposure while using the shading period and then pixel-mixing signals. Furthermore, it is possible to use the Archimedean spiral for the outer periphery of the diaphragm plate or the shading shutter.
