Abstract: A system and method for producing formatted information related to at least one image-capture appliance and/or at least one image-restitution appliance. The system and method provide for production of formatted information related to defects of the appliance, especially blurring and noise, from a measured field. This measured field is obtained from a universal set by performing the operations: capturing or restituting the universal set by the appliance to produce an image; choosing an image zone within the image; calculating a reference image from the image; selecting, within the reference image, a reference zone homologous to the image zone; choosing a base for representing all or part of the image zones and reference zones; selecting variable characteristics of the appliance; and in this way the measured field is obtained. The system and method are applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.

Abstract: A system and a method for calculating a transformed image from a digital image and from formatted information related to defects of an appliance chain for image capture and/or restitution. The system and method provide for automatically determining the characteristic noise data from formatted information and/or from the digital image. The transformed image can therefore be corrected such that it does not exhibit any visible or annoying defects, especially defects related to noise, as regards its subsequent use. The system and method are applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.

Abstract: A method and a system for producing formatted information related to defects of appliances of a chain of appliances. To produce the formatted information related to the defects of an image-capture appliance of the chain, the method includes a first calculation algorithm with which there can be chosen, within a set of parameterizable transformation models, within a set of parameterizable reverse transformation models, within a set of synthesis images, within a set of reference scenes, and within a set of transformed images: a reference scene, and/or a transformed image, and/or a parameterizable transformation model, with which a reference image of the reference scene can be transformed to the transformed image, and/or a parameterizable reverse transformation model, with which the transformed image can be transformed to the reference image, and/or a synthesis image obtained from the reference scene and/or obtained from the reference image.

Abstract: A method and system for providing, in accordance with a standard format, formatted information to an image-processor, especially software and/or components. The formatted information is related to defects of a chain of appliances including an image-capture appliance and/or an image-restitution appliance. The image-processor uses the formatted data to modify the quality of at least one image derived from or addressed to the chain of appliances. The formatted information includes data characterizing defects of the image-capture appliance, especially distortion characteristics, and/or data characterizing defects of the image-restitution appliance, especially distortion characteristics. The method fills in at least one field of the standard format with the formatted information. This field is designated by a field name and contains at least one field value.

Abstract: A method and system with which quality of an image derived from or addressed to a chain of appliances can be modified. Formatted information related to defects of the appliances is employed. The method and system: compile directories of sources of formatted information related to the appliances, search automatically for the formatted information related to the appliances, and modify the image automatically by image-processing software and/or image-processing components by taking into account the obtained formatted information. The formatted information can be modified as a function of variable characteristics of the image to be processed and/or the appliances. With the method and system it is possible to process images derived from appliances that have diverse origins and that have been commercialized gradually over time. Such a method and system are applicable to processing of photographic or video images and in optical instrumentation, industrial controls, robotics, metrology, etc.

Abstract: The invention relates to a processing system and method for producing formatted information related to the appliances (APP1 to 3) of an appliance chain (APP1). This appliance chain comprises in particular at least one image-capture appliance (APP1) and/or at least one image-restitution appliance (App3) for capturing and/or restituting an image (M) on a medium (SC). The invention aims at producing formatted information related to the geometric distortions of at least one appliance of the said chain. The invention provides different alternative embodiments, especially that with which fixed characteristics of the appliances and/or variable characteristics depending on the image (I) can be taken into account. The fixed characteristics and/or the variable characteristics are capable of being associated with one or more characteristic values, especially the focal length and/or the focusing.

Abstract: The invention concerns a method and a system for reducing update frequency of image processing means (P1), in particular a software and/or a component. The image processing means (P1) enable to modify the quality of digital images (P2) derived from and addressed to a set of appliances (P3). The set of appliances (P3) comprises an image capture device and/or an image scanning device. The image processing means (P1) use formatted data (P4) dependent on at least one variable, associated with the defects (P5) of at least on appliance (P25) of said set of appliances (P3). The formatted data include in particular parameters (P9) of at least a parameterable model dependent on said variables. The formatted data enable to establish a correspondence, in particular by means of a correspondence table, between part of said variables and identifiers. The identifiers enable to determine the value of the variable corresponding to an identifier taking into account said identifier and the image (P2).

Abstract: The invention relates to a system and a method for correcting the chromatic aberrations (1) of a color image (3) composed of a plurality of digitized color planes (4). This color image (3) is assumed to have been produced by means of an optical system (5). According to the invention, the geometric anomalies of the said digitized color planes (4) are modeled and corrected, at least partly, in such a way as to obtain corrected digitized color planes (17). The corrected digitized color planes (17) are then combined in such a manner as to obtain a color image (19) corrected completely or partly for the chromatic aberrations (1). The invention is applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.
