Abstract
Official abstract text for this publication.
A system for determining lens position including a first capacitor plate disposed on a stationary housing of a camera. A second capacitor plate is disposed on a rotating lens component of the camera. A processor is operatively connected to the first and second capacitor plates to identify the position of the lens of the camera based on capacitance between the first and second capacitor plates.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for determining lens position, comprising: a stationary lens barrel of a camera; a rotating lens component mounted for rotation relative to the lens barrel; a first capacitor plate disposed on the rotating lens component; three circumferentially spaced capacitor plates disposed on the stationary lens barrel surrounding the first capacitor plate; and a processor operatively connected to each of the capacitor plates to identify the position of…
