Method and apparatus for determining lens shading correction for a multiple camera device with various fields of view
Abstract:
A method and apparatus can determine lens shading correction for a multiple camera device with various fields of view. According to a possible embodiment, a flat-field image can be captured using a first camera having a first lens for a multiple camera device. A first lens shading correction ratio can be ascertained for the first camera. A second lens shading correction ratio can be determined for a second camera having a second lens for the multiple camera device. The second camera can have a different field of view from the first camera. The second lens shading correction ratio can be based on the first lens shading correction ratio and can be based on the flat-field image acquired by the first camera.
