  • Patent number: 7119930
    Abstract: The invention relates to a method of recording an image of an object (103) using an electronic camera (102), one or more light sources (104), and means for light distribution (105), where light emitted from the light sources (104) is distributed to illuminate the object (103), light being reflected to the camera (102). In the light distribution, an integrating cavity (106) is used to whose inner side (107) a light reflecting coating has been applied, and which is provided with first and second openings (109, 110). The camera (102) is placed in alignment with the first opening (109) so that the optical axis of the camera extends through the first and second openings (109, 110). The object (103) is received in the second opening (110), and the interior of the integrating cavity is illuminated using the one or more light sources (104). The invention also relates to an apparatus for performing the method.
