Claim 15:
16. A device for controlling a shade level of a motorized window treatment, the device comprising:
a control circuit, configured to:
obtain one or more images depicting an outside of a space, each of the one or more images comprising rows of pixels;
process 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 further causes the control circuit to:
start at a first pixel on a first row of pixels of the at least one image, and
step 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 the control circuit is configured to cease to process the at least one image 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

detect, 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.
