Abstract: A method, apparatus and computer program product are provided to signal grouping types in an image container file. Relative to the construction of an image container file, the method, apparatus and computer program product construct an image container file having a group box with a grouping type associated with burst-captured images, time-synchronized images captured by a plurality of image capture devices or an image item associated with an audio track. With respect to the processing of an image container file, the method, apparatus and computer program product permit an image container file having a group box with a grouping type associated with one of burst-captured images, time-synchronized images captured by a plurality of image capture devices or an image item associated with an audio track to be processed to cause one or more image items from the image container file to be rendered in accordance with the grouping type.

Abstract: The embodiments relate to a method comprising receiving visual data in a file format compatible with ISO base media file format; processing the visual data to detect one or more content elements; storing the detected one or more content elements and information on the used process as a metadata; and including the metadata to the media file in association with the visual data. The embodiments also relate to a technical equipment for implementing the method.

Abstract: The embodiments relate to a method comprising receiving visual data from image capturing means, said visual data comprising a plurality of entities (510); processing the visual data to determine one or more grouping types for at least selected entities of said plurality of entities (520); storing said one or more grouping types as a metadata of a container file format, said one or more grouping types being associated with said selected entities (530); and including the metadata to a container file in association with said visual data (540).
