Abstract: A method for capturing a digital panoramic image, includes projecting a panorama onto an image sensor by means of a fish-eye objective lens having a constant field angle relative to its optical axis. The image sensor is rectangular in shape. The fish-eye objective lens is provided to project onto the image sensor, without reducing the field of view, a distorted panoramic image that covers a number of pixels on the image sensor higher than the number of pixels that would be covered by an image disk.

Abstract: A method for capturing a digital panoramic image includes projecting a panorama onto an image sensor by means of a panoramic objective lens. The panoramic objective lens has a distribution function of the image points that is not linear relative to the field angle of the object points of the panorama, such that at least one zone of the image obtained is expanded while at least another zone of the image is compressed. When a panoramic image obtained is then displayed, correcting the non-linearity of the initial image is required and is performed by means of a reciprocal function of the non-linear distribution function of the objective lens or by means of the non-linear distribution function.

Abstract: The present invention relates to a method for capturing a digital panoramic image, by projecting a panorama onto an image sensor by means of a fish-eye objective lens having a constant field angle relative to its optical axis, the image sensor being rectangular in shape. According to the present invention, the fish-eye objective lens is provided to project onto the image sensor, without reducing the field of view, a distorted panoramic image (ID1) that covers a number of pixels on the image sensor higher than the number of pixels that would be covered by an image disk. Advantages: improvement in the definition in a useful zone of the image, particularly to improve the quality of digital zooms.

Abstract: A method for correcting the color of a digital panoramic image obtained uses at least one initial wide-angle image the image points of which are transferred into a three-dimensional coordinate system. The method includes inserting a color-grading zone into the initial image at the time of the exposure, the grading zone comprising at least three primary colors combined or presented in the form of a sequence of colors; detecting the color-grading zone in the panoramic image, performed by means of a digital image analysis algorithm; and correcting the colors of the image points of the digital panoramic image, performed with reference to the primary colors present in the grading zone.
