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： A scanning endoscope processor, comprising a photoelectric converter and a controller, is provided. The scanning endoscope processor controls a scanning endoscope having first and second transmitters and an actuator. The photoelectric converter receives light transmitted from the second transmitter and generates a pixel signal according to the amount of light received. The second transmitter transmits reflected light and/or fluorescence from a point within an observation area illuminated by the light emitted from a first emission end. The first transmitter emits the light as a beam from the first emission end. The actuator moves the first emission end along a spiral course. The controller adjusts at least one of a first angular velocity and a generation cycle so that the product of the first angular velocity, the generation cycle, and a first distance is within a predetermined range.

摘要： An electronic endoscope has a video-scope with an image sensor, a light source that emits illuminating-light to illuminate an object, an image sensor driver, a luminance detector, one rotary shutter, and a brightness adjuster. The luminance detector detects a luminance of an object image on the basis of image-pixel signals read from the image sensor. The rotary shutter has a light-transmitting portion that transmits the illuminating light, and a shield portion that blocks the illuminating light. The brightness adjuster controls the rotary shutter to adjust an irradiation-interval of the illuminating-light in accordance with a charge accumulation interval. The brightness adjuster shifts a rotation-phase of the rotary shutter by changing a rotation-speed on the basis of the detected luminance, so as to maintain a brightness of the object image at a proper brightness.

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： 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.
