Abstract
An apparatus and method for determining optical center in camera module are provided, the method for determining optical center in camera module according to an exemplary embodiment comprising receiving a target image from a camera module including a lens; generating an error data, which is a difference between a pixel value of the target image and a pixel value of a Gaussian distribution image; and determining the optical center of the lens based on the error data.
Claims13
An apparatus for determining an optical center in a camera module, the apparatus comprising:
- a camera module configured to obtain a target image through a lens;
- and
- a determinator configured to determine an optical center of the lens by using a pixel value of the target image obtained by the camera module,
- wherein the determinator comprises:
- a modeling unit configured to model a Gaussian distribution image;
- a generating unit configured to generate an error data, which is a difference between the pixel value of the target image and a pixel value of the Gaussian distribution image;
- and
- a center determinator configured to determine the optical center of the lens based on the error data.
