Definitions
- the invention relates to a communication system for recording and managing digital images.
- a camera for recording digital images is known from [1].
- a message transmission system is known from document [2].
- the invention is therefore based on the problem of creating a communication system for recording and managing digital images, in which the management and archiving of digital images can be carried out simply, quickly and clearly.
- the problem is solved by the communication system according to claim 1.
- the communication system has at least one camera for recording images, an image transmission unit as well as a transmission unit and a server.
- the camera is set up to take pictures that are stored in digital form in a camera memory of the camera.
- An image transmission unit is coupled to the camera. With the image transmission unit, the images are read out of the camera memory and fed to the transmission unit. With the sending unit, the images and the ordering features associated with the images, which characterize the images, are sent to a server.
- the server has a receiving unit, an analysis unit and an archive store. The transmitted data is received in the server with the receiving unit. The data are analyzed with the analysis unit with regard to the order features contained in the data and the images are archived in an archive memory coupled to the analysis unit, taking into account the order features.
- the communication system has a number of advantages.
- this communication system can also transmit still images, that is, photographs.
- the transmitted data contain the images as well as the order features clearly assigned to the images, which characterize the images.
- the order features are extracted from the data and used to store the digital images in such a way that they can be easily found in the server's archive memory, even with a large number of digital images to be archived and managed. In this way it is possible to ensure automatic archiving of the digital images in the server. Storage takes place depending on the extracted classification features, which enables simple, fast, clear archiving of digital images. Further developments of the invention result from the dependent claims.
- the transmission unit is a mobile telephone. This makes it possible to record the recorded image / voice information directly at any location and send it to a central server and thus to distribute the data in duplicate form without losing time.
- a further development of the communication system around a speech recognition unit in the telephone unit achieves additional compression of the data to be transmitted, since the audio information to be transmitted can be further compressed.
- the ordering features it is advantageous for the ordering features to have audio data. In this way, very simple, user-friendly archiving of the image data is achieved, since the user only has to speak information into the telephone unit about the captured image, as in the case of a telephone conversation.
- the audio data can also be provided in a form other than in speech as order features.
- the audio data can be present, for example, in specific noises characterizing the image data or in freely selectable music.
- the date and / or time of the acquisition of the image and / or the time of transmission of the data are used as ordering features.
- the order features can be extracted in the server in an extremely simple manner and converted directly into the information as to where in the archive store the digital images are to be stored in the server.
- the implementation can, for example take place that the received digital images are stored in directories of the archive memory in the server, which are divided according to the transmitted order features.
- the communication system can be implemented with less hardware expenditure and is therefore more cost-effective, since an extremely simple extraction of the order features and subsequent ones Implementation in the memory address of the archive store is achieved.
- an image analysis unit in the server for determining the quality of the images. If the required quality is higher than that supplied, a higher image resolution of the images can be requested from the server in a further embodiment. However, if the image quality compared to the actually required image quality in the server is higher than required, a lower data transmission rate can be set and images with lower image quality can be requested from the telephone unit. This enables the required transfer rate and the associated costs for transferring the images to be reduced.
- Image transmission unit is integrated in a connection between the camera and the transmission unit. This configuration makes the communication system even more flexible, since the camera, the image transmission unit and the transmission unit can be physically separate and only interact when the images are transmitted.
- An embodiment of the invention is shown in the figures and is explained in more detail below.

- the order features OM can be implicitly contained in the digital image itself, in particular in a specific semantics of the image content, in buildings, in a recorded landscape or in a recorded vehicle type.
- the analysis unit AE must be designed to analyze the image semantics. If the order features OM are implicitly contained in the digital image, the analysis unit AE is designed as a pattern recognition unit that searches for specific, predetermined features in the digital image.
- the order features OM can also be contained in the transmitted data which contain the digital images, in particular the address or the telephone number of the radio telephone 104 which transmits the data.
- the information about the date and / or the time of the recording time of the respective digital image and / or the sending of the respective digital image to the server 303 can also be contained in the data. If this is the case, the analysis unit AE is designed in such a way that this information can be extracted from the data. This corresponds to a simple analysis of the header field of the transmitted message that contains the data.
- the order features OM can contain the following types of information:
- audio data 501 for example melodies, songs, noises or also speech 502 spoken by the user into the radio telephone 104,
- the analysis unit AE is set up according to the type of the order features OM, so that the analysis unit AE is able to extract the order features OM from the data.
- Different forms of implementation can be used for this, for example any type of parser with which the respective information is extracted. Parsers are known from document [4].
- FIG. 4 shows the process for recording, transmission and archiving of recorded digital images in its individual process steps in a flow chart.
- a first step 401 the images are recorded with the camera 102.
- the images are stored in digital form as digital images in the camera memory 107 (step 402).
- the images are transmitted from the cellular phone 104 to the server 303 via the transmission system 302 (step 403).
- the data are received (step 404) and the order features OM, which characterize the digital images, are extracted (step 405) from the received data.
- the images and possibly additionally the order features OM and further information characterizing or describing the pictures are archived in the server 303, ie stored (step 406), the order features OM being taken into account during the archiving.
