Claim 0:
1. A method for detecting a location of a glare condition for controlling a shade position of a motorized window treatment, the method comprising:
obtaining one or more images of a view outside of a window on which the motorized window treatment is installed, each of the one or more images comprising rows of pixels;
processing the rows of pixels to calculate a respective luminance of multiple pixels of at least one image of the one or more images, wherein processing the rows of pixels comprises:
starting at a first pixel on a first row of pixels of the at least one image, and
stepping through each of the multiple pixels on the first row before continuing to a next row of pixels to determine the respective luminance of each of the multiple pixels of the at least one image until the location of the glare condition is detected, wherein processing the at least one image ceases upon detection of the location of the glare condition to avoid determination of the respective luminance for remaining unprocessed pixels of the at least one image; and

detecting, in response to the luminance of at least one of the multiple pixels of the at least one image, the location of the glare condition for controlling the shade position of the motorized window treatment.
