  • Method and device to obtain an element of information on depth in the field seen by picture-shooting device
    Patent number: 5534924
    Abstract: A method and an apparatus is disclosed for extracting from a single shot, two pictures of an illuminated scene having a foreground zone and a background zone respectively. The first picture has a depth of field which is greater than the second picture. Subsequently the high frequency components are extracted from each of the pictures in order to reflect characteristics of each of the pictures which have the greatest amount of contrast or sharpness. The two high frequency signals are compared in order to obtain a depth of field signal based upon the differences between the two signals.
