1. A method performed by a computing device for detecting presence of an illuminated graphical display of a mobile device within a motor vehicle, the method comprising:
- capturing, by a camera, an image of the vehicle being operated on a public roadway responsive to satisfaction of a trigger condition indicating presence of the vehicle;
receiving the image of the vehicle being operated on a public roadway captured by the camera;
determining a location of a driver'"'"'s seat region of the vehicle corresponding to a darker geometric region within the image that is representative of a window of the vehicle;
searching within window of the vehicle within the image for pixels of a signature pixel characteristic having a high luminosity relative to other pixels of the darker geometric region and/or a characteristic hue within a predefined range;
identifying an area of contiguous pixels of the signature pixel characteristic within the image indicative of the illuminated graphical display of the mobile device;
determining whether the area of contiguous pixels appears within a border of a trapezoidal shape having an aspect ratio that is within a predetermined range of a target 4;
3 aspect ratio; and
outputting an indication of a positive detection of the illuminated graphical display of the mobile device within the image if the aspect ratio of the border of the trapezoidal shape is within the predetermined range of the target 4;
3 aspect ratio.

Abstract
Embodiments for the detection of mobile device use in a motor vehicle are disclosed. As one example, a system and method are disclosed in which an image of a scene is captured via a camera. The presence of a graphical display of a mobile device is detected within the scene by processing the image to identify a signature pixel characteristic indicative of a graphical display in a portion of the scene corresponding to a driver'"'"'s position within a vehicle frame of reference. An indication of a positive detection of the graphical display is output by the system.

9. A system for detection of a driver'"'"'s mobile device use while operating a motor vehicle, comprising:
-
a camera positioned to capture an image of a driver'"'"'s side of the motor vehicle while the vehicle is being operated on a public roadway; and a computing device being configured to; capture, by the camera, the image of the vehicle being operated on the public roadway responsive to satisfaction of a trigger condition indicating presence of the vehicle; receive the image of the vehicle captured by the camera; determine a location of a driver'"'"'s seat region of the vehicle corresponding to a darker geometric region within the image that is representative of a window of the vehicle; search within window of the vehicle within the image for pixels of a signature pixel characteristic having a high luminosity relative to other pixels of the darker geometric region and/or a characteristic hue within a predefined range; identify an area of contiguous pixels of the signature pixel characteristic within the image indicative of an illuminated graphical display of the mobile device; determine whether the area of contiguous pixels appears within a border of a trapezoidal shape having an aspect ratio that is within a predetermined range of a target 4;
3 aspect ratio; andoutput an indication of a positive detection of the illuminated graphical display of the mobile device within the image if the aspect ratio of the border of the trapezoidal shape is within the predetermined range of the target 4;
