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.
