摘要： The present invention relates to utilization of metadata associated with a printed image. Portions of images and metadata are stored, each of the metadata being associated with a portion of the images. Imaging means are used to read a portion of the printed image. Correspondence between the read portion and the stored portions is determined. Metadata associated with a stored portion is retrieved in response to the determined correspondence between the read portion and the stored portion in question exceeding a predetermined threshold value. Further, the retrieved metadata or additional data indicated by it is retrieved.

摘要： 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, digitised 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.
