A method of selecting frames of a video sequence. Image data for a plurality of consecutive frames of the video sequence is captured using a camera. Frames from the plurality of consecutive frames where the camera is moving are identified using the captured image data, wherein each of the identified frames comprises a subject. A size of the subject captured in each of the identified frames is determined. The identified frames are selected by detecting that the camera is moving towards and with the subject based on the size of the subject within each of a plurality of the identified frames.

Method, system and apparatus for selecting frames of a video sequence

A method, apparatus and system of projecting text characters onto a textured document are described. The method comprises determining, from a captured image of the textured surface, a measure of the texture on the surface for a region of the textured surface over which the text characters are to be projected; selecting, based on a function of the determined measure, a glyph set, each glyph in the glyph set having visually contrasting inner and outer portions, the outer portion being sized proportionally to the inner portion according to the determined measure; and projecting the text characters onto the textured surface on of region using the selected glyph set.

Projecting text characters onto a textured surface

A method of displaying virtual content on an augmented reality device () is disclosed. The virtual content is associated with a scene. An image of a scene captured using the augmented reality device () is received. A viewing time of the scene is determined, according to a relative motion between the augmented reality device and the scene. Virtual content is selected, from a predetermined range of virtual content, based on the determined viewing time. The virtual content is displayed on the augmented reality device () together with the image of the scene.

Time constrained augmented reality

Methods of displaying video data are disclosed. The methods generate a plurality of queries for determining from which of a plurality of video data sources video data is to be displayed and store each of the queries. One of the queries is selected for display and the selected query is matched with metadata from one or more of the plurality of video data sources. The video data from the video data sources that match the query is displayed.

Dynamic layouts

A method of requesting video data distributed across a plurality of video servers(-N) connected to a communications network () is disclosed. A request (e.g.,) is transmitted to one of the video servers (e.g.,). The request () includes at least time information about at least a first portion of the video data. The first portion of video data is received from the video server (). A redirection message (e.g.,) is also received from the video server (). The redirection message () specifies a next one of the video servers () containing a temporally adjacent further portion of the video data.

Method of requesting video data distributed across a plurality of video servers

A method () of displaying video data using a video recording system (). The method () records a first stream of video data captured by a first camera (e.g.,) and a first event associated with the first camera (). The method records a second stream of video data captured by a second camera (e.g.,) and a second event associated with the second camera (). A playback speed is determined based at least on a difference between a current play time position and a time position of a nearest one of the first event and the second event. The first stream and the second stream of video data are displayed in a synchronized manner. The first stream of video data and the second stream of video data are displayed at the playback speed.

Method, apparatus and system for displaying video data

Disclosed is an arrangement () for displaying video footage captured by a controllable camera (), the arrangement comprising a memory () storing the captured footage, means for constructing a representation () of a field of view accessible by the camera (), means for retrieving, from the memory (), the stored footage () and parameters characterising the control state of the camera () when the footage was captured, and means for displaying the footage (), the representation () of the field of view, and an indicator () on the representation () dependent upon the parameters.
