Title:
STEREOSCOPIC VISION ENDOSCOPE DEVICE
Document Type and Number:
Japanese Patent JPS63262613
Kind Code:
A
Abstract:

PURPOSE: To execute a stereoscopic observation in a state having a large parallax by scarcely thickening an inserting part, by providing a mechanism for varying a visual field direction of an observing means, setting it in the visual field direction becoming roughly parallel to a different curved state, and obtaining a stereoscopic image, based on the respective observation images.

CONSTITUTION: By turning of a rotary plate 18, in a state of A and a state of B, an object area to which an SID (solid-state image pickup element) 15 executes an image pickup in common increases, in comparison with the case said plate does not turn. In this state, a control circuit 34 allows an image memory 43 to record image data which has been brought to an image pickup by the SID 15. Outputs of the image memories 42, 43 are inputted to an image processing means 33, and the image processing means 33 calculates three- dimensional information of an object, from these two pieces of images having a parallax (d). In such a way, the calculated three-dimensional information is displayed on displays 44, 45, but the displayed image is shifted a little, and seen stereoscopically, when it is observed by both eyes 50, 50 through eyepieces 48, 49.
