A method is proposed of encoding a change time The change time indicates a change in time of a characteristic luminance of the video data. The characteristic luminance summarizes the set of luminances of pixels the video data. The encoding of the time variation of the characteristic luminance provides a more compact and accurate storage and transmission of content.

A method and apparatus analyze a difference of at least two gradings of an image on the basis of: obtaining a first graded picture (LDR) with a first luminance dynamic range; obtaining data encoding a grading of a second graded picture (HDR) with a second luminance dynamic range, different from the first luminance dynamic range; and determining a grading difference data structure (DATGRAD) on the basis of at least the data encoding the grading of the second graded picture (HDR), which allows more intelligently adaptive encoding of the imaged scenes, and consequently also better use of those pictures, such as higher quality rendering under various rendering scenarios.

Apparatus and methods for analyzing image gradings

This invention provides a process which allows better quality rendering of video on any display. The process proposes encoding, video data and additional data. The additional data includes a change time instant. The change time instant can be used to indicate a change in time of a characteristic luminance. The characteristic luminance summarizes the set of luminances of pixels in an image of the video data. The process includes generating on descriptive data based on the video data and encoding and outputting the descriptive data as additional data.

A system and method of processing video data: produce, on the basis of the video data, descriptive data regarding a variation in a characteristic luminance of the video data, wherein the characteristic luminance summarizes the set of luminances of pixels in an image of the video data, wherein the descriptive data identifies the at least one change time instant, wherein the change time instant indicates a time at which a change of the characteristic luminance occurs; and encode and output the descriptive data.

The present invention relates to assisting a user in selecting a lighting device design by providing a lighting device design based on a model or image of a lighting device design (e.g. the user uploading an image of an existing lighting device in his/her home). The lighting device design of the model or image is analyzed in order to determine a lighting device design related variable (e.g. type, shape or color of lighting device design). This variable is then used to select a lighting device design from a set of lighting device designs (e.g. to select a lighting device design of the same color, from an electronic catalogue of lighting device designs); or to generate a lighting device 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.

Assisting a user in selecting a lighting device design

The present invention relates to suggesting a lighting device () 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 () 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 () design is then provided (e.g. selected or generated) based on the lighting device design related variable and an image () of the provided lighting device () design is displayed.

An apparatus for determining a propagation velocity for a surface wave comprises a coherent light source () for generating at least a first and a second light spot on a surface (). A camera () captures at least one out-of-focus image of at least a part of the surface () comprising the light spots. The out-of-focus image comprises light spot image objects for the light spots where the light spot image objects have speckle patterns. An analyzer () determines the propagation velocity in response to a time difference between speckle pattern changes in the two speckle patterns. The camera may specifically use a rolling shutter allowing the determination of the propagation velocity to be based on a spatial analysis of the speckle patterns. The approach may in particular allow an efficient remote measuring of pulse wave velocities e.g. in animal tissue and in particular, in human tissue.
