First Claim
Patent Images
1. A system comprising:
- a control system configured to issue commands;
a camera system in communication with and physically separated from the control system, the camera system including;
a) a lens including optical elements;
b) an image sensor configured to capture images storable within the system; and
c) camera control apparatus configured to;
i. receive a zoom command from the control system to perform a zoom movement within the camera system;
ii. determine zoom speed information of the camera system; and
iii. move a displayed field of view of the camera system at a positioning speed based on the determined zoom speed information to correct for a bore-sight offset of the camera system as the zoom movement is performed in accordance with the zoom command.

Abstract
A camera system is provided that provides a smooth and centered zoom, even at high levels of magnification. The camera system corrects for misalignment between the optical axis of a lens and center of an image sensor. As a result of the misalignment, the center of an image will move during a zoom movement. The current camera system corrects for the misalignment as the zoom movement occurs. The correction is matched to the speed of the zoom in order to provide a fluid zoom movement.

19. A memory having stored thereon instructions for execution by a processor comprising part of a camera system, wherein the camera system also comprises a lens and an image sensor and wherein the instructions when executed by the processor cause the camera system to perform the following:
-
receive zoom information for performing a zoom movement; determining zoom speed information of the camera system; and move a displayed field of view of the camera system at a positioning speed based on the determined zoom speed information to correct for a bore-sight offset of the camera system as the zoom movement is performed. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
