  • Patent number: 8212889
    Abstract: The invention concerns a method for activating a function by using a measurement taken from at least one digital image (10) having at least two colors (195, 196) and originating from an image-capturing apparatus, the method including measuring the relative sharpness (190) between at least two colors in at least one region R of the image, and Controlling at least one action (191) depending on the measured relative sharpness.
    Type: Grant

  • Patent number: 7920172
    Abstract: A method for activating a function by using a measurement taken from at least one digital image having at least two colors and originating from an image-capturing apparatus, wherein a relative sharpness is measured between at least two colors on at least one region of the digital image, and at least one function is activated depending on the measured relative sharpness.

  • Publication number: 20080158377
    Abstract: The invention concerns a method for activating a function by using a measurement taken from at least one digital image (10) having at least two colours (195, 196) and originating from an image-capturing apparatus. According to such method: the relative sharpness is measured (190) between at least two colours in at least one region R of the image, and at least one action is controlled (191) depending on the measured relative sharpness.

  • Patent number: 7346221
    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.

  • Patent number: 7343040
    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.
