Abstract
The technology relates to determining whether a camera is occluded. For instance, an image may be captured using a camera having red, green, and blue pixels each including a photosensor. Output values for the photosensors of each of the red pixels, green pixels, and blue pixels may be determined for the images. The output values of the green pixels may be compared to one or more of the output values of the red pixels or the output values of the blue pixels. That the camera is occluded is determined based on the comparison.
Claims20
A camera comprising:
- an image sensor including a plurality of photosensors each corresponding to one of a plurality of differently colored pixels;
- and
- a controller including one or more processors operably coupled to the image sensor, wherein the one or more processors are configured to:
- determine output values for the plurality of photosensors for an image;
- compare the output values for the plurality of photosensors corresponding to pixels having a first color to one or more of the output values for the plurality of photosensors corresponding to pixels having a second color;
- and
- determine, based on results of the comparison, whether the camera is occluded.

A method comprising:
- determining, by one or more processors of a controller of a camera, output values for a plurality of photosensors or an image;
- comparing, by the one or more processors, the output values for the plurality of photosensors corresponding to pixels having a first color to one or more of the output values for the plurality of photosensors corresponding to pixels having a second color;
- and
- determining, by the one or more processors based on results of the comparing, whether the camera is occluded.
