Definitions

  • the present invention relates to systems, devices, and methods that generate a lighting script from content displayed or to be displayed on a screen, where the lighting script is configured to drive light sources for providing light output related to or associated with the content.
  • Display devices to enhance the viewing experience of television viewing through lighting applications have been introduced.
  • a particularly interesting application is to project light on a wall from light sources surrounding a display, the so-called AmbiLight television (TV) from Philips Electronics as depicted in FIG 1 showing a display device 100 such as a TV which may be a flat TV which is hung on a wall.
  • Controllable light sources 110 such as LED bars, are provided around the TV surrounding a display area or screen 120 where images or content are displayed.
  • the light sources 110 emit surround light 130, for example, to wash the back wall (on which the TV is hung) with what is referred to as AmbiLight.
  • the AmbiLight concept aims at enlarging the perceived image size through lighting effects or ambient light 130 surrounding the displayed image.
  • the color of the ambient light 130 emitted from the light units or sources 110 is dynamically changed by sampling the video content that is currently being watched by the user, for example.
  • the ambient light feature primarily involves automatic triggering of light effects based on the content that is currently being consumed by the user, where consumption refers to users or viewers watching movies, listening to music, browsing photos, etc.
  • the content may be live or stored locally, for example, on a digital versatile disc (DVD) or hard drive of a personal video recorder (PVR).
  • a TV may be provided with or coupled to a device with a surround light feature having light speakers, e.g., tower speakers with on-board light units, which may be integrated with or a stand alone device along with the TV and/or a home entertainment system.
  • the light speakers are triggered based on the audio and/or visual content that is being consumed by the user thereby creating an immersive experience for the user.
  • the light effects may be realized by real-time analysis of the content stored or displayed through a unit such as a PVR or DVD player, a TV integrated with processing platform, a home theatre system, etc.
  • the light effects may be stored as a script on e.g., on a DVD, as a separate track or may be downloaded from the Internet, and the script executed when the content is rendered thus generating light effects associated with or related to the content.
  • the script may be generated in real-time during rendering, e.g. displaying, the content on the TV or any display device.
  • Ambient light 130 is automatically triggered when the content is rendered, e.g., when video content is displayed on the display area 120, by analyzing the color information in the content.
  • the color of the ambient light 130 depends on the color information inherent in the content, particularly, the color of the content around the boundary of the scene or edges of the display area 120 of the TV 100.
  • the intensities and colors of the ambient light 130 depend on the video content displayed on the display area 120. For example, if the video content near one side of the TV 100 has a green color, then green light is provided from this side to backwash the back wall near this light with green light. Similarly, if the video content near another side of the TV 100 has a yellow color, then yellow light is provided from this other side to backwash the corresponding wall portion with yellow light, for example.
  • the ambient light 130 with various attributes, such as various colors and intensities is provided from the four sides of the TV 100 to illuminate the surrounding environment, such as the back wall, with a desired ambilight or light scenario.
  • the lighting scenario is either provided with the video content via a script accompanying the content, for example, or derived from the video content through content analysis such as in real-time as the video is being rendered.
  • Systems with active or passive ambient light features are described in International Publication No. WO 2006/003603 Al, entitled “Passive Diffuser Frame System for Ambient Lighting Using a Video Display Unit as a Light Source", filed on June 27, 2005, published on January 12, 2006, and as described in International Publication No. WO
  • the light source(s) 110 that provide ambient light 130 may be controlled by a processor in response to the content information displayed on the display image area 120, such as via RF signals received by the display device from a broadcast for example, or video signals derived from the RF signals using modulators or other circuits needed for such controlled operation, as described in the above referenced International Publication Nos. WO 2006/003603 and WO 2006/003604, as well as described in International Publication No. WO 2005/062608, entitled "Supplementary Visual Display System", filed on December 20, 2004, published on July 7, 2005, and assigned to the assignee hereof, the content of which is incorporated herein by reference in its entirety. Accordingly, the ambient light 130 will be related to, and/or derived from, the content displayed on display image area 120 under the control of a processor, for example.
  • the human perception of color is a complex process.
  • color features are treated at the pixel level. This assumes that the perception of a color is not influenced by the surrounding colors.
  • computing the color associated with a particular image or region in an image all pixels are considered and contribute to the final result regardless of the fact that the value of some of the pixels might strongly depend on noise inherently present in the image.
  • a "segment" of N pixels of the same color is considered to have the same influence as if the N pixels were scattered throughout the whole image. This clearly violates the human perception of colors in a complex image. Accordingly, there is a need for better content analysis or script generation used for controlling light sources to provide light having attributes, such as color and intensity, that more closely match the displayed content.
  • One object of the present systems is to overcome the disadvantage of conventional ambient light displays.
  • At least one light source provides ambient light under the control of a processor.
  • the processor is configured to generate a lighting script from coherent pixels of at least one portion of the content including discarding incoherent pixels of the at least one portion, and to control the at least one light source in accordance with the lighting script.

  • Color space of the image is discretized into N distinct (discretized) colors/color buckets, and each pixel is associated with a particular color bucket.

The color information of the content is transformed or mapped from the RGB space onto the color space of the LEDs and the displayed color space. In addition, the transformed color information of the content, e.g., the RGB coordinates, are transmitted to the LED units or light sources Ll to L6 so as to trigger them to provide ambient light 130 having light attributes that are associated with the content displayed at the respective regions Rl to R6.

  • [R; G; B] corresponds to the triplet which is the computed average color information for a particular region for all channels.
  • the general method for computing the matrix M is shown below:
  • the transformed color information for the upper region may be sent to both the LED panels Ll , L2 located at the top of the TV 360.
