A scanning endoscope device that obtains a parallax image, comprising: a first core portion that radiates an illuminating light beam for a first viewpoint toward a subject, the illuminating light beam having a first optical characteristic; a second core portion that is provided parallel to the first core portion and that radiates an illuminating light beam for a second viewpoint toward the subject simultaneously with the radiation by the first core portion, the illuminating light beam having a second optical characteristic different from the first optical characteristic; one driving unit (4, 7) that is provided in common with the first core portion and the second core portion and that two-dimensionally scans the illuminating light beam radiated from the first core portion and the illuminating light beam radiated from the second core portion by causing vibration of the distal-end portions of the first core portion and the second core portion together; a light receiving unit that receives return light beams, returned from the subject, of the illuminating light beam radiated from the first core portion and the illuminating light beam radiated from the second core portion; a light splitting unit that splits the return light beams received by the light receiving unit into a return light beam having the first optical characteristic and a return light beam having the second optical characteristic; a first light detecting unit that photoelectrically converts the return light beam split by the light splitting unit and having the first optical characteristic to output a first captured image signal for the first viewpoint; a second light detecting unit that photoelectrically converts the return light beam split by the light splitting unit and having the second optical characteristic to output a second captured image signal for the second viewpoint; and an image generating unit that generates a first image for the first viewpoint based on the first captured image signal output from the first light detecting unit and that generates a second image for the second viewpoint based on the second captured image signal output from the second light detecting unit. a first core portion that radiates an illuminating light beam for a first viewpoint toward a subject, the illuminating light beam having a first optical characteristic; a second core portion that is provided parallel to the first core portion and that radiates an illuminating light beam for a second viewpoint toward the subject simultaneously with the radiation by the first core portion, the illuminating light beam having a second optical characteristic different from the first optical characteristic; one driving unit (4, 7) that is provided in common with the first core portion and the second core portion and that two-dimensionally scans the illuminating light beam radiated from the first core portion and the illuminating light beam radiated from the second core portion by causing vibration of the distal-end portions of the first core portion and the second core portion together; a light receiving unit that receives return light beams, returned from the subject, of the illuminating light beam radiated from the first core portion and the illuminating light beam radiated from the second core portion; a light splitting unit that splits the return light beams received by the light receiving unit into a return light beam having the first optical characteristic and a return light beam having the second optical characteristic; a first light detecting unit that photoelectrically converts the return light beam split by the light splitting unit and having the first optical characteristic to output a first captured image signal for the first viewpoint; a second light detecting unit that photoelectrically converts the return light beam split by the light splitting unit and having the second optical characteristic to output a second captured image signal for the second viewpoint; and an image generating unit that generates a first image for the first viewpoint based on the first captured image signal output from the first light detecting unit and that generates a second image for the second viewpoint based on the second captured image signal output from the second light detecting unit.
