Title:
LENS ECCENTRICITY ADJUSTING METHOD AND LENS DEVICE
Document Type and Number:
Japanese Patent JP3206840
Kind Code:
B2
Abstract:
PURPOSE: To provide a means for preventing the partial blurring of an image by adjusting the eccentricty of a lens or a lens group when the eccentricity occurs.
CONSTITUTION: The lens or the lens group 4 is positionally adjusted along a plane 14 perpendicular to an optical axis P so that resolution concerning two optional points on an image plane which are at positions point-symmetrical to each other with the optical axis P as center may be nearly the same. In any case that the lens 4 is inclined to the optical axis or axis misalignment is caused, deviation occurs in the resolution between two points which are pointsymmetrical. Therefore, by forcibly performing the axis misalignment of the lens 4, the deviation in the resolution is corrected and the partial blurring of the image is eliminated.
