Abstract: A lighting system (100) comprising a central lighting device (111), at least one satellite lighting device (121, 131), and a controller (141) for adjusting light settings, is provided. The controller is arranged for transmitting, in response to a user request (140), an association request over a first communication link (142). The central lighting device is arranged for receiving the association request and re-transmitting the association request over a second communication link by means of coded light (112). The satellite lighting device is arranged for transmitting, in response to receiving the association request, its identifier to the central lighting device. The identifier is only transmitted if an association process is enabled. The association process is enabled, in response to a user request, during a limited time period. The central lighting device is further arranged for associating, in response to receiving the identifier, the satellite lighting device with the central lighting device.

Abstract: The invention provides a user interaction system (100) and a method of controlling a lighting system. The user interaction system (100) comprises a display (106), a means for receiving a location indication (102), a location identification means (104) and an overlay image creator (108). The display (106) displays a subarea image and an overlay image. The subarea image is an image of a specific subarea of the environment. The location identification means (104) detects which specific location in the environment is indicated by the location indication. The overlay image creator (108) generates the overlay image. The overlay image comprises information related to a lighting effect which is obtainable by the lighting system at the specific location. The obtainable effect is an effect of at least two controllable light sources of the lighting system.

This method comprises accessing a user profile comprising the user's brain signals mapped to mental task descriptions, accessing an application profile (38) comprising a plurality of properties of the application, matching one or more mental task descriptions from the user profile to a respective property from the application profile, and creating a brain computer interface accordingly.

Abstract: It is quite common for users to have both video and photo material that refer to the same event. Adding photos to home videos enriches the content. However, just adding still photos to a video sequence has a disturbing effect. The invention relates to a method to seamlessly integrate photos into the video by creating a virtual camera motion in the photo that is aligned with the estimated camera motion in the video. A synthesized video sequence is created by estimating a video camera motion in the video sequence at an insertion position in the video sequence at which the still photo is to be included, creating a virtual video sequence of sub frames of the still photo where the virtual video sequence has a virtual camera motion correlated to the video camera motion at the insertion position.

Abstract: To adjust colors in an input image (II) to colors of a reference image (RI), matching reference points (RP) are provided in the input image (II) and the reference image (RI), dominant colors of the matching reference points (RP) are determined (10, 20), and the colors in the input image (II) are transformed (30, 40) based on the dominant colors of the matching reference C points to obtain an output image (OI).

Abstract: The invention relates to local luminaire control in an area based lighting control system. A basic idea of this invention is to use a soft switch assigned to one or more luminaries of an area based lighting control system to locally control the luminaire/ies, wherein the soft switch is adapted for generating an appropriate signal for the area based lighting control system, that puts the luminaire/ies in the desired state.

Abstract: A method of suggesting accompaniment tracks for synchronised rendering with a content data item includes obtaining data descriptive of the content data item. A database query based at least partly on the data descriptive of the content data item to identify auxiliary content items to a user is resolved. The database (14;28) includes records, each configured to associate descriptive data with an auxiliary content data item for forming an accompaniment track. Data representative of a selection of an auxiliary content data item is received in association with the query, and a database record for the selected auxiliary content data item is caused to be amended to reflect the selection in association with at least part of the descriptive data included in the query.
