US 2025/0059828 A1 · SENSOR FOR DETECTING GLARE CONDITIONS

Abstract

A sensor and/or system controller may process an image multiple times at multiple resolutions to detect glare conditions. A glare condition threshold used to determine whether a glare condition exists may be based on the resolution of the image. When the resolution of the image is higher, the glare condition threshold may be higher. The sensor and/or system controller may organize one or more adjacent pixels having similar intensities into pixel groups. The pixel groups may vary in size and/or shape. The sensor and/or system controller may determine a representative group luminance for the pixel group (e.g., an average luminance of the pixels in the group). The sensor and/or system controller may determine a group glare condition threshold, which may be used to determine whether a glare condition exists for the group of pixels and/or may be based on the size of the group.

Dependent claims

An apparatus for detecting a location of a glare condition and for controlling a position of a motorized window treatment, the apparatus comprising:

a communication circuit;
and
a control circuit configured to:
determine a desired position to which to control the position of the motorized window treatment based on an indication of a location of a glare condition in an image;
determine that the desired position is higher than a present position;
compare a difference between the desired position and the present position to a raise threshold to determine that the difference is greater than or equal to the raise threshold;
and
transmit, via the communication circuit, control instructions for controlling the position of the motorized window treatment based on the desired position being higher than the present position and the difference being greater than or equal to the raise threshold, wherein the control instructions are configured to instruct the motorized window treatment to raise the position if the difference is greater than or equal to the raise threshold.

A method of detecting a location of a glare condition and controlling a position of a motorized window treatment, the method comprising:

determining a desired position to which to control the position of the motorized window treatment based on an indication of a location of a glare condition in an image;
determining that the desired position is higher than a present position;
comparing a difference between the desired position and the present position to a raise threshold to determine that the difference is greater than or equal to the raise threshold;
and
transmitting control instructions for controlling the position of the motorized window treatment based on the desired position being higher than the present position and the difference being greater than or equal to the raise threshold, wherein the control instructions are configured to instruct the motorized window treatment to raise the position if the difference is greater than or equal to the raise threshold.

2 more elements

One or more non-transitory computer readable media having instructions stored thereon that, when executed by a control circuit, cause the control circuit to:

determine a desired position to which to control the position of the motorized window treatment based on an indication of a location of a glare condition in an image;
determine that the desired position is higher than a present position;
compare a difference between the desired position and the present position to a raise threshold to determine that the difference is greater than or equal to the raise threshold;
and
transmit, via a communication circuit, control instructions for controlling the position of the motorized window treatment based on the desired position being higher than the present position and the difference being greater than or equal to the raise threshold, wherein the control instructions are configured to instruct the motorized window treatment to raise the position if the difference is greater than or equal to the raise threshold.
