Abstract: The invention relates to a method of annotation of images captured by a digital camera equipped with a previewing means, comprising: the supply with the camera of an operating mode enabling a user to select one image (12) to be annotated, and to capture at least one additional previewed image; the automatic extraction (20) of an annotation (A) from the additional image; and the creation (22) of a new image by combining the annotation (A) and the image to be annotated (12), while respecting, in the new image, a location and enlargement ratio of the annotation virtually identical to those of the annotation in the additional image.

Abstract: The invention relates to a method of data transmission by an ad-hoc network of mobile communication equipment (16a, 16b, 16c, 16d), from at least one source equipment (12) to at least one collection terminal (14), by means of mobile relay equipment (16c), in which for each communication equipment, at least one quality factor is updated (Q0, Q1, Q2 Q3, Q4, Q5). According to the invention, the quality factor of each relay equipment depends on a history of data transmission, and data transmission from mobile equipment to mobile relay equipment is conditional on the quality factor of the relay equipment capable of receiving the data.

Abstract: A method of distributing multimedia data from a central distribution station to local equipment including: linking one image characteristic (32, 34, 36, 38, 40, 42, 44, 46, 48) with at least one set of multimedia data stored by the central distribution station respectively; making available to at least one user of a support (10) having at least one selection image (12, 14, 16, 18, 20, 22) in response to the capture of at least one image of the support by the local equipment, and calculating a characteristic of the captured image; searching for a multimedia data set of the central station linked to the image characteristic closest to the characteristic calculated; transferring of the corresponding multimedia data to the local equipment.

Abstract: The invention relates to a variable focal length lens with a chamber (10) having symmetry of revolution around an axis (14) and containing one first transparent fluid (20) and one second transparent fluid (22) that have different optical indices and are immiscible, so as to form a meniscus (24), and that have different electrical conductivities, and means (30, 40) to modify the curvature of the meniscus. According to the invention, the means to modify the curvature of the meniscus comprises means of applying an electric field dissymmetrical in relation to the axis of said chamber. The invention has applications in the production of cameras.

Abstract: The invention is in the field of digital imaging. The invention relates more specifically to a method for automatically adding and finding characterization data linked to images. The method is implemented in a cellular communications network (1). The method according to the invention is used in a cellular communications network (1), and enables fast, user-friendly and private, management of image characterization data, such as their geolocalization.

Abstract: An image processing system includes a client device including a limited display having a resolution less than VGA and a bit depth less than 24 bits for displaying a low resolution digital image and image processing operation indicators, an operator interface for user input, a CPU and a memory, the CPU being capable of running a limited client image processing program, and a first communication port; an image processing server for performing an image processing operation on a high definition image stored at the image processing server, for producing a low resolution version of the image for display on the limited display of the client device, and for producing image processing operation indicators indicating a particular image processing operation, the image processing server including a second communication port and being responsive to remote user inputs to produce a processed digital image; and a limited bandwidth mobile communication network connectable with the first and second communication ports for tran

Abstract: The present invention concerns a method for managing a quick distribution of images. The method comprises the following steps: receiving, from a user, at least one image associated with a messaging system address; digitizing said at least one image when the image is not in digital form; storing said at least one image on a server; and sending a message to the messaging system address associated with said at least one image giving the information that said at least one image is available on the server.
