1. An image processing system, comprising:
- a data communication network (1) over which an image being processed is transmitted, the image being represented by image data digitized in an electronic form of representation;
an image correcting device (2a) connected to the data communication network (1), the image correcting device being configured to process the image to enhance the image visual quality and/or print the image to different formats;
wherein the image correcting device includes a classifying device for automatic classification of the image, the classifying device (3) including an adding device arranged to add information data to the image data, the information data added by the classifying device classifies the subject matter of the image and provides specific processing instructions in the form of metadata;
wherein the image correcting device further includes a correcting device (4) for automatic correction of the image, the image correcting device arranged to add information data to the image data, wherein the information data added by the correcting device improves the quality of the image by providing specific processing instructions in the information data; and
a plurality of image processing devices (2a, 2b, 2c) connected to the data communication network (1), each image processing device including a profile generating device arranged to extract processing instructions from the metadata, the profile generating device being configured to process the image according to the processing instructions.

Abstract
The invention relates to a system and a procedure for image processing. The system comprises a data communication network (1) which serves as a channel for the transmission of the image being processed, digitized in an electronic form of representation, and an image processing device (2; 2a, 2b, 2c), which is connected to the data communication network (1) and which processes the image to enhance its visual quality to print the image to different formats. According to the invention, the image processing system comprises a classifying device (3), which automatically classifies the image, and a correcting device (4), which automatically corrects the image.

4. A procedure for image processing comprising the steps of:
-
transmitting an image digitized in an electronic form along a data communication network;
processing the image in an image correcting device connected to the data communication network to enhance its visual quality;
printing the image in different formats;
automatically classifying the image in the image correcting device based upon the subject matter of the image; and
automatically correcting the image in the image correcting device to improve the quality of the image;
wherein information data is added to the image data by the image correcting device, the information data being related to the classifying and correcting of the image data and comprising device specific processing instructions in the form of metadata; and
wherein the image is processed in an output device connected to the data communication network according to the processing instructions extracted from the information data, wherein the processing instructions are specific for the output device. - View Dependent Claims (5, 6, 7, 8)
