  • a computer program for encoding information in an image frame displayed by a display screen comprising instructions such that when the computer program is executed on a computing device, the computing device is arranged to: encode information in an image frame to add the information to content in the image frame so as to be displayed, using visible light, at at least one portion of the display screen, the encoding being carried out by setting at least one of the luminosity and the hue of the pixels at the at least one portion of the display screen, wherein the value that is set for said at least one of the luminosity and the hue of the pixels at the at least one portion of the display screen is dependent on a measured temperature of the at least one portion of the display screen.
  • visible light communication information can be added to content which is to be displayed on a screen.
  • Display screens are used in many different types of consumer apparatus including for example television screens,
  • the apparatus is arranged such that the hue of the pixels are set by adjusting one or more of the red, green and blue values associated with the pixels at the at least one portion of the display screen.
  • the apparatus is arranged such that each of the red, green and blue values associated with the pixels at the at least one portion of the display screen can be adjusted independently of each other.
  • a computer program for encoding visible light communication information in an image frame to add the visible light communication information to content in the image frame displayed by a display screen comprising instructions such that when the computer program is executed on a computing device which has circuitry for measuring the temperature of at least one portion of the display screen during use, the computing device is arranged to: encode visible light communication information in an image frame to add the visible light communication information to content in the image frame so as to be displayed at at least one portion of the display screen, the encoding being carried out by setting at least one of the luminosity and the hue of the pixels at the at least one portion of the display screen, wherein the value that is set for said at least one of the luminosity and the hue of the pixels at the at least one portion of the display screen for the encoding of the visible light communication information in the image frame is dependent on the measured temperature of the at least one portion of the display screen.

  • Display screens are used in many different types of consumer apparatus including for example television screens, the display screen is susceptible to distortion. Therefore, incorrect visible light communication information, if any at all in some cases, may be transmitted from the display screen to a recipient device. Examples described herein adapt the appearance of the visible light communication as encoded, having taken into consideration the temperature of the corresponding portion of the display screen at which the visible light communication is to be displayed.
  • Figure 1 shows an example system 100 for determining the temperature of one or more portions of a display screen, and to set at least one of the luminosity and hue values used for encoding visible light communication information in the pixels associated with the one or more portions of the display screen based on the measured temperature(s).
  • the system 100 carries out a temperature check 102 to determine the temperature of one or more portions of the display screen when image/video information to belbeing displayed at the display screen is encoded with visible light communication information.
  • the temperature check 102 may for example determine the temperature of the entire display screen as a whole or separately of one or more portions of the display screen.
  • the temperature check 102 may in one example be circuitry arranged to measure field use temperature 104 of the at least one portion of the display screen when an image/video to be displayed at the display screen is encoded with visible light communication information.
  • the measure field use temperature 104 of the at least one portion of the display screen is used to determine the luminosity and/or hue of the at least one portion of the display screen that is to be used when encoding visible light communication information in an image frame for display at the display screen.
  • determining the hue of the display screen may comprise determining the RGB (red, green and blue) values for pixels or groups of pixels associated with the at least one portion of the display screen.
  • RGB pixels of a display screen typically comprise 3 sub-pixels: red, green and blue (and optionally others, in other schemes, such as RGB and yellow, RGB and white, etc.).
  • the output of at least one of the RGB sub-pixels may be modified to take into account the current temperature of the display screen at that part of the display screen.
  • the values used for each of the sub-pixels may be independently increased or decreased as necessary.
  • the luminosity and/hue of the display screen may be determined by a display modifier 106.
  • the temperature check 102 determines whether the temperature of the display screen in use is above or below a threshold value. If the temperature is below the threshold value, pre-defined default luminosity and/or hue settings are used at the display screen when visible light communication information is encoded in an image frame displayed at the display screen or at different portions of the display screen. If the temperature is above the threshold value, the luminosity and/or hue settings are modified such that the visible light information encoded in the image/video is not distorted by the temperature of the display screen or different temperatures at different portions of the display screen. This may, for example, involved increasing/decreasing the luminosity and/or hue values of the display screen. In another example, the threshold value may be a temperature range.
  • the luminosity and/or hue of the at least one portion of the display screen are kept at the default predetermined value(s) when encoding the visible light information. Conversely, if the temperature of the display screen is outside the threshold temperature range, the luminosity and/or hue of the at least one portion of the display screen are modified such that the visible light information encoded in the image/video is not distorted by the temperature of the display screen or different temperatures at different portions of the display screen.
  • the temperature check 102 determines whether the measure field use temperature 104 of the display screen in use is above or below an initial temperature reading(s) 108 of the device.
  • the initial temperature reading(s) 108 may be for one or more portions of the display screen arranged to display visible light communication information encoded in an image frame.
  • the initial temperature reading(s) 108 is/are stored at an initial temperature reading data store or "look-up" table 110.
  • the initial temperature reading(s) 108 of the display screen may be taken after the display screen has been functioning for a pre-determined period of time.
  • the display screen is arranged to function for a pre-determined manufacture "warm-up" time.
  • the warm-up time is required to allow all components of and relating to the display screen to reach a normal functioning temperature.
  • an initial temperature reading(s) 108 of at least one portion of the display screen is taken.
  • the initial temperature reading(s) 108 may be for each pixel or even sub-pixel (e.g. the RGB sub-pixels) of the display screen.
  • the display screen will be used by end users in the field.
  • the display screen is turned on and allowed to function for a field use "warm-up" time.
  • the field use warm up time may be the same as or different from the manufacture warm up time. Having different warm-up times may be particularly important in devices exposed to extreme temperatures or wide temperature ranges, such as for example so-called "signage" display screens.
  • the field use warm-up time allows all components of and relating to the display screen reach a normal functioning temperature.
  • the field use temperature 104 of at least one portion of the display screen is determined when visible light communication information is to be added to an image/video for display at the display screen.
  • the temperature check 102 is arranged to compare the field use temperature reading 104 for the at least one portion of the display screen and the initial temperature reading 108 for the at least one portion of the display screen when visible light communication information is to be added to an image/video for display at the display screen.
  • the temperature check 102 receives the initial temperature reading 108 from the data store/"look-up" table 110.
  • the display modifier 106 of the visible light communication coder 104 is arranged to modify the settings of the display screen to prevent unwanted modifications from occurring to the visible light communication information that is to be encoded to content being displayed at the display device.
  • the temperature check 102 may be arranged to determine the field use temperature 104 of the display screen at regular intervals of time. Alternatively or additionally, the temperature check 102 may be triggered to measure the temperature of the display screen once the display screen reaches a threshold temperature.
  • a display screen is arranged to display an image/video encoded with visible light communication information.
  • a field use temperature reading 104 may be taken to determine the temperature of at least one portion of the display screen.
  • the field use temperature reading 104 is compared with an initial temperature 108 of the at least one portion of the display screen.
  • the initial temperature 108 may be stored in a data store or "look-up table" 110.

  • the VLC (visible light communication) coder 112 determines the location of the at least one portion of the display screen exhibiting the highly different field use temperature 104 on the display screen. Initially, in a specific example for illustrative purposes, the portion of the display screen exhibits an RGB value of 200, 150, 200. Upon determining that the portion of the display screen is exhibiting a highly different field use temperature 104, a display modifier 106 of the VLC coder 112 is arranged to set new luminosity and/or hue values of the display screen. In this example, the RGB value of the at least one portion of the display screen is set at 180,170, 210. New luminosity and/or hue values to be applied to a display screen may be stored at a data store or "look-up" table, or calculated on-the-fly.
