Definitions

  • the present invention relates to method and apparatus for capturing metadata for a content item, e.g. a photograph, a video segment or an audio segment.
  • Metadata or annotations are required to assist users in browsing images in their increasingly large collections. Given the large number of images, manually adding metadata or annotations is not a realistic option. Consequently, as much metadata as possible should be generated automatically. Examples of metadata are the time, date and location that are captured when the picture is taken. Furthermore, metadata may include the names of the persons captured by the image. These may be identified by facial recognition techniques.
  • the image capture device communicates with external devices.
  • the external devices such as smart tags etc.
  • These tags send information to the image capture device to identify the object and from this information the metadata is generated.
  • Identification of a person captured by the image can be made by use of facial recognition software.
  • This software is complex and expensive and the processing required slows down the automatic generation of the metadata.
  • the image capture device is a portable device, the power consumption of running such software is, invariably, unacceptable.
  • the performance of facial recognition is typically very sensitive to the lighting conditions on the image and the position of the face in the image. This can lead to inaccurate results.
  • the content item may be a still picture, a video segment or an audio segment, for example.
  • a method for identifying at least one person within a vicinity of a location of capture of a content item comprising the steps of: receiving a unique identifier, the unique identifier not being part of the content item; and identifying said at least one person from said received unique identifier.
  • an apparatus for identifying at least one person within a vicinity of a location of capture of content comprising: a receiver for receiving a unique identifier, the unique identifier not being part of the content item; and processing means for identifying said at least one person from said received unique identifier.
  • any persons regardless of whether or not they were captured by the content item can be identified.
  • the method and apparatus of the present invention do not rely on analysis of the content item after it has been captured since it receives identifiers at the time the content item is captured to identify the persons present. Furthermore, it does not require use of facial recognition software.
  • the unique identifier or information derived from the unique identifier may be embedded in the content item or may be stored separately to the content item.
  • the unique identifier is stored in the metadata and in a second embodiment, also the "friendly name" of the corresponding person is stored in the metadata.
  • the browser needs to have the translation table between unique identifier and "friendly name”. This may require an additional Bluetooth receiver and/or additional manual effort to create the mapping table.
  • the unique identifier should preferably be in the metadata as well, as not all people may be known.
  • a method for enabling to browse a plurality of content items each of said plurality of content items having metadata associated therewith, said associated metadata comprising a unique identifier for identifying a person who was present within a vicinity of a location of said each image when it was captured, the method comprising the steps of: selecting from said plurality of content items at least one content item, the person identified by the unique identifier of the metadata associated with the selected content item matching a selected person; and enabling browsing of said at least one content item.
  • an apparatus enabling browsing of a plurality of content items, each of said plurality of content items having metadata associated therewith, said associated metadata comprising a unique identifier identifying a person who was present within a vicinity of a location of said each content item when it was captured, the apparatus comprising: a selector for selecting from said plurality of content items at least one content item, the person identified by the unique identifier of the metadata associated with the selected content item matching a selected person; and means for enabling browsing of said at least one content item.
  • the user can then easily browse stored content items, e.g. images, and present a personalised view of those content items in which a particular person was present when the content item was captured regardless of whether or not the person was captured by the content item.
  • stored content items e.g. images
  • a method for exchanging content items at least a first communication terminal having access to at least one content item, said content item having metadata associated therewith, said associated metadata comprising a unique identifier for identifying a person who was present within a vicinity of a location of the content item when it was captured, the method comprising the steps of: said first communication terminal enabling the identified person to access to the at least one content item.
  • the method may further comprise the step of a second communication terminal sending a request to said first communication terminal for at least one content item in which a specified person was present within the vicinity of the location of the content item when it was captured.
  • an apparatus for exchanging content items said apparatus having access to at least one content item, said content item having metadata associated therewith, said associated metadata comprising a unique identifier for identifying a person who was present within a vicinity of a location of the content item when it was captured, the apparatus comprising: means for enabling the identified person to access the at least one content item.
  • Content items e.g. digital images, can, therefore, be easily exchanged or shared among those persons present when the image was captured.
  • the communication terminals comprise mobile telephones which may have integral image capture devices (cameras).
  • Many mobile telephones include Bluetooth transceivers.
  • the Bluetooth network technology covers a limited range, typically 10 - 10O m, dependent on the power class in which the devices operate. In the preferred embodiments, this network is used to collect a list of the Bluetooth devices in the vicinity at a certain point in time.
  • the bluetooth module may be integrated in a digital image capture device (camera). At the moment of capturing an image, the device stores the list of bluetooth devices it detects in its vicinity within the metadata to associate with the image being captured.
  • another device that typically is used in conjunction with the digital image capture device, has a bluetooth module that records a list of bluetooth devices (e.g. mobile telephones) that it detects in its vicinity, as a function of time. This information is later correlated to the images taken by an image capture device by using the time that images were captured.
  • Figure 1 is a simple schematic of apparatus according to an embodiment of the present invention
  • Figure 2 is a flow chart of the method steps according to an embodiment of the present invention
  • Figure 3 is a flow chart of the method steps according to another embodiment of the present invention.
  • the apparatus comprises a transceiver 101 which receives incoming transmissions containing a unique identifier of a device within the range of the apparatus.
  • the unique identifier is the bluetooth identification of the device within the short range of communication of the apparatus.
  • the output of the transceiver 101 is connected to a processor 103.
  • the apparatus further comprises an integral image capture device 105 which is connected to the processor 103 and an image store 107.
  • the processor 103 is also connected to the image store 107.
  • the processor 103 may also access a local memory store 109. Operation of the apparatus will now be described with reference to figure 2.
  • the transceiver 101 of the apparatus transmits a request, as the user activates the image capture device 105 to capture an image, via short-range wireless communication, such as bluetooth, to other bluetooth devices within its range (vicinity), step 203.
  • Each bluetooth device responds to the request and transmits its unique identifier to the transceiver 101 of the apparatus.
  • the transceiver 101 receives a list of unique identifiers within its vicinity, step 205.
  • the processor 103 looks up the unique identifiers in its local memory store 109 which includes a table of mappings of unique identifiers and the name of the person associated with that unique identifier.
  • this step may be carried out at a later stage, for example after capturing the image / just before storing the person information.
  • the mappings are stored in a remote database, for example a database accessed via the Internet.
  • the processor 103 identifies the person who is in the vicinity of the device, step 207.
  • the image is captured by the image capture device 105, step 209, and the digital image is stored in the image store 107 with associated metadata or annotation which includes a list of those unique identifiers which were also in the vicinity of the device when the image was captured and a list of the persons who were in the vicinity of the device when the image was captured.
  • the list of unique identifiers which were in the vicinity of the device when the image was captured may contain identifiers for which no mapping to the name of the person is known (person unknown), step 211. If the mapping table is in a remote device, the retrieval of names associated with identifiers may have to be postponed.
  • the method of this embodiment comprises an additional step, step 301, in which the transceiver 101 continuously scans the network for which devices are present.
  • step 301 the transceiver 101 continuously scans the network for which devices are present.
  • the devices present at that moment are stored and the persons in the vicinity of the location when the image is captured can be identified.
  • the table of mappings can be extended to include a history log file, which indicates that a person is identified by a unique identifier (bluetooth device) between certain dates. This can, therefore, take into account any change of ownership of a device and correctly identify the person present.
  • the table of mappings may be built by the user and stored in local memory
  • mappings can be made available via other services such as Internet services, where users can register their bluetooth devices and link them to their own identification.
  • Metadata can be generated including information about which persons were present on the occasion a certain image was captured.
  • This increases the recognition rate, as conventional face recognition software is not required. It can be used to create a personalised view of the image collection of a family, for example show me all pictures "when I was there" regardless of whether or not captured by the images. Further, it can be used to facilitate sharing of images between people that were on the same occasion. For example, images can be exchanged where I was present and sent to another who was also present on the same occasion. In this situation, it may very well be possible that the other user is not known to the sender.
  • the bluetooth device identifier can be used to find these people/their pictures.
