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： To provide a timing generator which generates a first reference signal at a standard speed of approximately 14 MHz and a second reference signal operating at approximately 28 MHz which is double the standard speed and forms a moving image based on the first reference signal, reads, when a freeze switch is operated, an image pickup signal based on the second reference signal operating at the double speed and writes this signal into the memory 36 at the same speed. Then, by reading this still image signal from the memory at the standard speed, the still image is displayed on the monitor. Thereby, the need for setting a conventional light shielding period can be eliminated.

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： This electric mask generating apparatus reads mask bit string generation data, which has a configuration of one pixel per bit and is set in ROM, by a microcomputer, develops the mask bit string generation data in RAM, and thereafter writes the mask bit string generation data in mask generation memory. This electric mask generating apparatus reads a mask signal in this mask generation memory by a microcomputer, and mixes an image signal of an object with the above-described mask signal by using a shift register or the like in a mask-mixing circuit. According to the mask signal having this configuration of one pixel per bit, since it is possible to write the mask signal in the above-described mask generation memory during the time that is one-eighth of conventional write time, it becomes possible to quickly display an image to which a normal mask or a scaled mask is given.
