Abstract
A method and apparatus of aligning a lens module with respect to an image sensor device for a capsule camera are disclosed. The image sensor device comprises multiple pixel arrays and the lens module comprises multiple lens sets to form multiple images corresponding to multiple fields of view associated with the multiple lens sets, and each lens set forms one image for one corresponding pixel array associated with one field of view. A method according to the present invention present invention, one or more test images are presented in the multiple fields of view associated with the lens module. Multiple images in the multiple fields of view are captured using the multiple pixel arrays. Metric measurement is derived based on the multiple images captured by the multiple pixel arrays. Lens alignment between the lens module and the image sensor device is then adjusted based on the metric measurement.
