Abstract: A method for automatically producing a digital image includes selecting at least one capture mode for capturing at least two image signals from an image capture device. The image capture device captures at least two image signals of the same scene in a RAW format, each image signal being captured according to the image capture mode. A file in a standardized format comprising each image signal and metadata representative of the capture mode is generated and stored. The created file is digitally processed by selecting at least one processing algorithm to process at least two image signals according to the metadata representative of the capture mode, and by fusing at least two image signals according to each chosen image processing algorithm into a fused digital image signal.

Abstract: A processing system and method for producing formatted information related to appliances of an appliance chain. This appliance chain includes at least one image-capture appliance and/or at least one image-restitution appliance for capturing and/or restituting an image on a medium. The system and method produce formatted information related to geometric distortions of at least one appliance of the chain. Fixed characteristics of the appliances and/or variable characteristics depending on the image can be taken into account. The fixed characteristics and/or the variable characteristics can be associated with one or more characteristic values, especially the focal length and/or the focusing. Then, measured formatted information related to the geometric distortions of the appliance are produced from a measured field. 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 correcting chromatic aberrations of a color image composed of a plurality of digitized color planes. The color image is assumed to have been produced by an optical system. According to the system and method, geometric anomalies of the digitized color planes are modeled and corrected, at least partly, in such a way to obtain corrected digitized color planes. The corrected digitized color planes are then combined to obtain a color image corrected completely or partly for the chromatic aberrations. The system and method are applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.

Abstract: Th invention relates to a method and system for modifying a digital image (100) consisting of pixels. Said digital image is divided into areas (103). At least one area value is assigned to each area Zi (103). At least one parameter value Vpij (203) is assigned to each of said areas (103). A set of couples (Zi, Vpij) forms a parameter image (201). The inventive method consists (a) in determining the determined parameter values Vpir for each area (103), the parameter image (201) being called determined parameter image, (b) in adjusting the determined parameter image by reducing the variations thereof, (c) in modifying pixel values (102) of the determined pixel (101) of said digital image (100) according to the parameter values (203) of said adjusted parameter image, whereby the digital image is differentially modified for each of said pixels and quasi regularly for contiguous areas.

Abstract: The invention relates to a system and method for calculating a transformed image from a digital image and formatted information related to a geometric transformation, especially formatted information related to the distortion and/or chromatic aberrations of an appliance chain. This calculation is carried out on the basis of an approximation of the said geometric transformation. The invention is applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.
