  • Patent number: 10600170
    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.

  • Patent number: 9536284
    Abstract: A method and a system are described where the quality of an image can be modified, using formatted information related to the defects of the appliances of the chain of appliances. The method may include compiling directories of sources of formatted information related to the said appliances, searching automatically for this formatted information related to the appliances of the said chain of appliances, modifying the said image automatically by image-processing software or components by taking into account the formatted information. Additionally, the formatted information may be modified as a function of variable characteristics of the image to be processed and of the chain of appliances. Thus, it is possible to process the images derived from appliances that may be of diverse origins and that have been commercialized gradually over time, such as photographic or video images in optical instrumentation, industrial controls, robotics, metrology, etc.

  • Patent number: 8994873
    Abstract: A system for capturing at least one image of a scene. The system estimates at least one value representative of the sharpness in at least one area of at least one initial captured image of a scene. The autofocus module captures the initial image with a predefined focus. On the basis of at least the value representative of the estimated sharpness, the system selects a first operating mode or a second operating mode. In the first mode, the autofocus module controls the focus of the system to capture a sharper image of the scene. In the second mode, the initial captured image or another captured image is processed by the digital processing unit, the other image being captured with the predefined focus.

  • Patent number: 8736683
    Abstract: The invention relates to a method for estimating a defect in an image-capturing system (I), which produces, with regard to any first image (I), representing any scene (S), a variation in the field of a characteristic of the first image, having an order of magnitude that is statistically lower than a variation in the field of said characteristic added by the scene. The method comprises: calculating, in at least a first portion of the field of the first image, a measurement (?(I)) related to said characteristic of the first image, an estimative magnitude (?) of said defect, depending on the calculated measurement and having a variation having the same order of magnitude as the variation in the field of said characteristic of the first image produced by said defect.

  • Patent number: 8634004
    Abstract: Method of monitoring an image capture system (1) comprising a sensor (C) comprising a plurality of photosensitive elements (Z1, Z2, Zn) and an optical device (L) for focusing the light emitted from a scene towards the sensor. This method comprises the obtaining (100) of respective responses of certain at least of the photosensitive elements (E1, E1?, P1, P2) of the sensor to an exposure of the image capture system to any scene (S), followed by a determination (200) of at least one deviation (?) between at least one quantity (G) deduced from the responses obtained and at least one reference quantity (Gref). These steps may be followed by an estimation (300) of an optical effect of the image capture system (1) on the basis of said deviation (?) determined and optionally by an implementation of an action able to at least partially compensate (400) for the estimated optical defect.
