Abstract

The present disclosure provides example methods operable by computing device. An example method can include receiving an image from a camera. The method can also include comparing one or more parameters of the image with one or more control parameters, where the one or more control parameters comprise information indicative of an image from a substantially unobstructed camera. Based on the comparison, the method can also include determining a score between the one or more parameters of the image and the one or more control parameters. The method can also include accumulating, by a computing device, a count of a number of times the determined score image exceeds a first threshold. Based on the count exceeding a second threshold, the method can also include determining that the camera is at least partially obstructed.

Description

[0001] Cross References to Intersecting Applications [0002] This application claims priority to US Patent Application Serial No. 13 / 855,054, filed April 2, 2013, the entire contents of which are hereby incorporated by reference. Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0004] Mobile devices such as smartphones and tablets are gradually offering better cameras that capture higher quality digital images. In addition, stand-alone compact cameras, digital SLR cameras, and mirrorless interchangeable-lens cameras are becoming popular. Accordingly, the number of captured high-quality images is rapidly increasing. However, images are often captured by devices that are obscured by dust, grease, or other foreign objects. Despite advances in image capture technology, the quality of images captured thr...
