BINOCULAR STEREOSCOPIC OBSERVATION DEVICE, ELECTRONIC IMAGE STEREOMICROSCOPE, ELECTRONIC IMAGE STEREOSCOPIC OBSERVATION DEVICE AND ELECTRONIC IMAGE OBSERVATION DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide an observation device having a wide range where an observed image can be focused by an observer, and yielding a stereoscopic image giving little fatigue. PSOLUTION: The binocular stereoscopic observation device is constituted of an image pickup part for picking up the image from right and left directions where parallax exists, and an observation part for stereoscopically observing the image having the parallax. The image pickup part has (i) image pickup positions in each optical path, and is constituted so that a distance LSBj/SBon an optical axis to the (j)-th image pickup position from an imaging lens, a difference Ek between distances on the optical axis to the imaging lens from the adjacent image pickup positions, and the image-side depth Dd of the optical system of the image pickup part satisfy LSB(j-1)/SBLSBj/SBEk=LSBj/SB-LSB(j-1)/SBDdEk. The observation part has an eyepiece optical system and (i) display devices in each optical path, and displays the image picked up at the (j)-th image pickup position in the image pickup part on the (j)-th display device from the eyepiece optical system and is constituted so that a distance MSBj/SBon the optical axis to (j)-th display device from the eyepiece optical system satisfies MSBj/SBMSB(j-1)/SB, and has a means for superposing (i) display images on observer's pupil. Provided that (i) is an integer 2, and(j) is an integer satisfying 1ji and j2. PCOPYRIGHT: (C)2005,JPO&NCIPI
