Detection of traffic light signal changes
First Claim
1. A computer-implemented method of detecting a traffic light signal change, the method comprising:
- determining, by a user device, that a user is stopped at an intersection having a traffic light;
capturing, by the user device, a plurality of images in response to detecting that the user is stopped at the intersection having a traffic light, wherein the plurality of images do not depict the traffic light;
detecting, by the user device, a tonal shift in one or more color values associated with at least one surface depicted in at least one image of the plurality of images, the at least one surface being separate from the traffic light, the tonal shift being indicative of a change in signal provided by the traffic light; and
providing, by the user device, a notification to the user indicative of the change in signal produced by the traffic light based at least in part on detecting the tonal shift in the one or more color values associated with the at least one surface that is separate from the traffic light.

Abstract
Systems and methods of detecting traffic light signal changes are disclosed. For instance, it can be determined that a user is stopped at an intersection having a traffic light. A plurality of images can be captured in response to detecting that the user is stopped at the intersection having a traffic light. The plurality of images do not depict the traffic light. A tonal shift in one or more color values associated with at least one image of the plurality of images can be detected. The tonal shift is indicative of a change in signal provided by the traffic light. A notification indicative of the change in signal provided by the traffic light can be provided to the user.

11. A computing system, comprising:
-
one or more processors; and one or more memory devices, the one or more memory devices storing computer-readable instructions that when executed by the one or more processors cause the one or more processors to perform operations, the operations comprising; determining that a user is stopped at an intersection having a traffic light; capturing a plurality of images in response to detecting that the user is stopped at the intersection having a traffic light, wherein the plurality of images do not depict the traffic light; detecting a tonal shift in one or more color values associated with at least one surface depicted in at least one image of the plurality of images, the at least one surface being separate from the traffic light, the tonal shift being indicative of a change in signal provided by the traffic light; and providing a notification to the user indicative of the change in signal produced by the traffic light based at least in part on detecting the tonal shift in the one or more color values associated with the at least one surface that is separate from the traffic light.

12. One or more tangible, non-transitory computer-readable media storing computer-readable instructions that when executed by one or more processors cause the one or more processors to perform operations, the operations comprising:
-
determining that a user is stopped at an intersection having a traffic light; capturing a plurality of images in response to detecting that the user is stopped at the intersection having a traffic light, wherein the plurality of images do not depict the traffic light; detecting a tonal shift in one or more color values associated with at least one surface depicted in at least one image of the plurality of images, the at least one surface being separate from the traffic light, the tonal shift being indicative of a change in signal provided by the traffic light; and providing a notification to the user indicative of the change in signal produced by the traffic light based at least in part on detecting the tonal shift in the one or more color values associated with the at least one surface that is separate from the traffic light.
