Abstract
Technologies are generally described for systems, devices and methods effective to detect a presence of a display. In some examples, a processor may receive image data from a camera. The image data may relate to light incident on the camera. The processor may analyze the image data to determine that the light includes flickering at a frequency. The processor may detect the presence of the display based on the frequency of the flickering.
Claims24
A method to detect a presence of display, the method comprising by a processor:
- receiving image data from a camera, wherein the image data relates to light incident on the camera;
- analyzing the image data to determine that the light includes flickering at a frequency;
- and
- detecting the presence of the display based on the determined flickering and frequency of the flickering.
A device effective to detect a display, the device comprising:
- a memory that includes instructions;
- a camera effective to receive light incident on the camera and produce image data in response to the light;
- a processor configured to be in communication with the memory and the camera, the processor configured to:
- receive the image data from the camera;
- analyze the image data to determine that the light includes flickering at a frequency;
- and
- detect the presence of the display based on the determined flickering and frequency of the flickering.
A method to detect two displays, the method comprising, by a processor:
- receiving image data from a camera, wherein the image data relates to light incident on the camera;
- analyzing the image data to determine that the light includes flickering;
- determining a first frequency of flickering in the image data;
- determining a second frequency of flickering in the image data, wherein the second frequency of flickering is different from the first frequency of flickering;
- detecting the presence of a first display based on the determined flickering and the first frequency of the flickering;
- and
- detecting the presence of a second display based on the determined flickering and the second frequency of flickering.
