<P>PROBLEM TO BE SOLVED: To provide an endoscope device by which an operator is not required to intentionally adjust an irradiation light amount confirming a picked up image both in an ordinary observation and in a special light observation, and which can usually obtain a picked up image with a stable brightness and a color tint with respect to observation of a structure and a component of living body such as surface microscopic blood vessels regardless of an image pick up distance. <P>SOLUTION: The endoscope device includes: a first light source section to emit narrow band light; a second light source section to emit wide band light; a light source control section to control light emission and light emission amounts from the first and the second light sources; an imaging means that images a pick up image using returned light from the subject; a light amount calculating means that calculates a photographing light amount; a light amount ratio calculating means that calculates a ratio of light emission amounts from the first and the second light source sections, and an image processing means that performs a prescribed image processing. The light source control section controls the light emission amounts in accordance with the photographing light amount and the image processing means changes an image processing condition for adjusting a color tint of the photographing image in accordance with the ratio of the light emission amounts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
