First Claim
Patent Images
1. A method programmed in a non-transitory memory of a device comprising:
- a. calibrating the device using a first distance between a second nodal point and an image sensor; and
b. calibrating the device using a second distance between a first nodal point and the second nodal point.

Abstract
The thick lens calibration method enables better calibration of complex camera devices such as devices with thick lens systems. The thick lens calibration method includes a two step process of calibrating using the distance between a second nodal point and an image sensor, and calibrating using the distance between the first and second nodal point.
