Corrective lens assembly
First Claim
1. A lens assembly comprising:
- a first lens mounted on a holder, said holder for attaching said first lens to a viewing device of an image capturing device;
a marking on said first lens, said marking having a first size and being observable through said viewing device when attached to said viewing device such that said marking is capable of being used to position said lens assembly a first distance from a first object having a predetermined second size, wherein a relationship, seen through said viewing device, between said first size and said second size determines said first distance.

Abstract
A lens assembly, image capturing device and a method for using a lens assembly with an image capturing device. The lens assembly comprises a first lens mounted on a holder which attaches the first lens to a viewing device of an image capturing device. A marking on the first lens is observable through the viewing device when the lens is attached to the viewing device such that the marking is capable of being used to position the lens assembly a properly focused distance from a target having a specified (predetermined) size. The relationship, as seen through the viewing device between the size of the object and the size of the marking may be used to properly position the camera relative to the target object.

7. A method for using a lens assembly with an image capturing device, said method comprising:
-
viewing a first object through a viewing device, said viewing device being optically coupled to a first lens of said lens assembly; matching a marking, which appears in a view through said viewing device, relative to said first object, said marking having a first size and said first object having a predetermined second size, wherein said step of matching causes said image capturing device to be positioned a first distance from said first object. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An image capturing device comprising:
-
a primary lens optically coupled to an image capturing medium; a viewing lens optically coupled to a viewing device; a first corrective lens optically coupled to said primary lens; a second corrective lens optically coupled to said viewing lens, said second corrective lens having a marking which is observable through said viewing device such that said marking is capable of being used to position said image capturing device a first distance from a first object, said marking having a first size and said first object having a predetermined second size such that a relationship, as seen through said viewing device, between said first size and said second size determines said first distance. - View Dependent Claims (15, 16, 17, 18, 19, 20)
