  • Publication number: 20050068454
    Abstract: The present invention aims at depth or field improvements or digital cameras, where differently-focused images of a scene, to be photographed, are exposed. A final image is produced from these primary-shots, where depth of field-limitations related to classic photo-lenses, are essentially eliminated. Specific new problems related to camera-viewfinders and camera-focusing are emerging however, due to the increasing number of image % being registered. Following the present invention, advantageous procedures regarding camera viewfinders, for visualizing the individual primary shots as well as images processed for improved depth of field, are outlined. A simple technique for upgrading a standard digital camera for depth of field-improvement operation, including an adequate method for preselecting focuses, is illustrated by FIG. 5. These problems and others, related to a photographers adjustments and handling of various kinds of depth of field-enhancing cameras are remedied by applying the present invention.

  • Publication number: 20040080661
    Abstract: The object of the present invention is to eliminate hitherto restrictive conditions related to photography, like when attempting to register pictures with infinite depth of field, more or less, or attempt full detail-reproduction of light and shade. This is, according to the present invention, accomplished by making several recordings with differing states of focus or exposure, the images registered being similarly subdivided into smaller image-parts and a resultant image bing produced by selecting those image-parts from each set, being most suitable. Optimal image definition of an image-part can for instance be assessed by contrast-measurement techniques or separate range-finding with a laser. An analogous optimal representation of image detail can also be achieved.
