Document Type and Number:
Japanese Patent JP6660823
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an endoscope apparatus which uses an imaging unit with two imaging elements laminatingly mounted thereon to enable simultaneous observation of reflection from a subject caused by white light and fluorescence from the subject caused by excitation light with a desired performance attained.SOLUTION: Used is an imaging unit 21 on which are mounted laminatingly, from the side receiving light from a subject, a first light permissive film 60 shielding excitation light, a first imaging element 83 photoelectrically converting white light, and a second imaging element 87 photoelectrically converting fluorescence which has transmitted through the first light permissive film 60 and the first imaging element 83, such that the reflection from the subject and the fluorescence from the subject caused by the excitation light are observed simultaneously. A timing control unit 69 causes an excitation light source K2 to illuminate at least during an illuminating period of a white light source K1 to allow that an image signal from the second imaging element 87 is read simultaneously with the reading of an imaging signal from the first imaging element 83 during at least a part of a period during which the image signal from the first imaging element 83 is read.SELECTED DRAWING: Figure 8
