1. A method for detecting a location of a glare condition and for controlling a shade position of a motorized window treatment, the method comprising:
retrieving an image;
processing the image at a first resolution to detect a first glare condition, wherein the first glare condition is detected when a luminance value of a pixel in the image processed at the first resolution exceeds a glare condition threshold associated with the first resolution;
processing the image at a second resolution to detect a second glare condition, wherein the second glare condition is detected when a luminance value of a pixel in the image processed at the second resolution exceeds a glare condition threshold associated with the second resolution; and
transmitting control instructions configured to control the shade position or a position associated with the first glare condition or the second glare condition in the image, and wherein the control instructions are configured to control the shade position based on one or more of the first glare condition or the second glare condition.
