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 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.
