Publication number: 20150286724Abstract: The present invention relates to suggesting a lighting device (408) design to a user, such as in an advertisement for a lighting device design. The suggestion is based on acquiring user interest information relating to the user from a data source such as an online user profile. A lighting device (408) design related variable (e.g. intensity, colour temperature) is determined based on the acquired user interest information using, for example, a lookup table or rules. A lighting device (408) design is then provided (e.g. selected or generated) based on the lighting device design related variable and an image (410) of the provided lighting device (408) design is displayed.Type: ApplicationFiled: October 24, 2013Publication date: October 8, 2015Inventors: Bram Knaapen, Petrus Johannes Hendrikus Seuntiens, Chris Damkat, Bartel Marinus Van De Sluis, Wei Pien Lee, Stefan Donivan Twigt

Publication number: 20150278896Abstract: The present invention relates to assisting a user in selecting a lighting device (204) design by providing a lighting device (204) design based on a model or image of a lighting device (204) design (e.g. the user uploading an image of an existing lighting device in his/her home (200)). The lighting device (204) design of the model or image is analyzed in order to determine a lighting device (204) design related variable (e.g. type, shape or color of lighting device design). This variable is then used to select a lighting device (204) design from a set of lighting device (204) designs (e.g. to select a lighting device (204) design of the same color, from an electronic catalogue of lighting device designs); or to generate a lighting device (204) design (e.g. to generate a lighting device design that is a copy of the lighting device design in the image, only smaller and in a different color). The invention further includes a system and computer program product for implementation of this method.Type: ApplicationFiled: October 24, 2013Publication date: October 1, 2015Inventors: Petrus Johannes Hendrikus Seuntiens, Bram Knaapen, Bartel Marinus Van De Sluis, Chris Damkat, Anthonie Hendrik Bergman, Wei Pien Lee, Tim Dekker, Stefan Donivan Twigt, Robertus Antonius Jacobus Maria Hovers, Bertrand Rigot

Publication number: 20140029665Abstract: An encoder comprises a receiver (101) for receiving a video signal comprising at least one image. An estimator (107) determines a veiling luminance estimate for at least part of a first image of the at least one image in response to image content of one or more of the images. The veiling luminance estimate reflects an amount of eye glare generated in the eye by the image when rendered. A quantization adapter (109) determines a quantization scheme for the at least part of the first image in response to the veiling luminance estimate and an encoding unit (103, 105) encodes the video signal using the quantization scheme for the at least part of the first image. The veiling luminance estimate may be low-pass filtered to emulate human luminance adaptation. A corresponding decoder is provided. Improved encoding can be achieved, especially for High Dynamic Range images.Type: ApplicationFiled: March 30, 2012Publication date: January 30, 2014Applicant: KONINKLIJKE PHILIPS N.V.Inventor: Chris Damkat

Patent number: 8538201Abstract: The invention relates to upscaling of images such as upscaling of video images from standard definition to high definition. An input image is upscaled to a resolution enhanced image (207) by weighting pixel values in the input image depending on a match metric combining two match metrics. A first image generator (103) generates a blurred version of the input image and a second image generator (103) generates an upscaled interpolated version. The first metric is generated by comparing pixel sets of the blurred image and the upscaled interpolated image. A second metric is generated by comparing pixel sets of the input image and already synthesized pixel values of the resolution enhanced image (207). For each location in a search area, a resolution enhancement processor (107) generates the combined match metric and uses this to weigh the pixel value of that location when generating the unknown pixel value of the resolution enhanced image (207).Type: GrantFiled: May 14, 2009Date of Patent: September 17, 2013Assignee: TP Vision Holding B.V.Inventor: Chris Damkat
