Abstract
The present application relates to image capture and generation methods and apparatus and, more particularly, to methods and apparatus which detect and/or indicate a dirty lens condition. One embodiment of the present invention includes a method of operating a camera including the steps of capturing a first image using a first lens of the camera; determining, based on at least the first image, if a dirty camera lens condition exists; and in response to determining that a dirty lens condition exists, generating a dirty lens condition notification or initiating an automatic camera lens cleaning operation. In some embodiments multiple captured images with overlapping image regions are compared to determine if a dirty lens condition exists.
