Abstract: An endoscope apparatus includes a CCD disposed at a distal end portion of an endoscope insertion section, a first LED and a second LED functioning as illumination-light emitting unit, a region setting section that sets a first region where illumination by the first LED is predominant on an endoscopic image and a second region where illumination by the second LED is predominant on the endoscopic image, and a white balance circuit that respectively calculates color balance values corresponding to the first and second regions and applies correction processing to a color balance value of a video signal of the entire endoscopic image on the basis of results of the respective calculations.

Abstract: A medical device includes a curving motion driver curving a treatment portion, a rolling motion driver rolling the treatment portion in a direction around an axis, an instruction input unit inputting an instruction to move the treatment portion to a desired position, and a position/posture detector which detects a position and a posture of the treatment portion when the instruction is input from the instruction input unit. The medical device includes a driving information calculator which calculates driving information of the curving motion driver and the rolling motion driver during the movement of the treatment portion to the desired position on the basis of the detected position and posture of the treatment portion and on the basis of the input in the instruction input unit, and a control unit which drives and controls the curving motion driver and the rolling motion driver in accordance with the calculated driving information.
