  • Publication number: 20100220986
    Abstract: The method of manufacturing a photograph comprises, in the following order, the steps: a) focussing, so as to reach a first focussing state (A), which is a desired in-focus state with respect to an image plane (87) of a focussed-state detection arrangement (70); b) shifting from said first focussing state (A) to a second focussing state (B), which is different from said first focussing state (A); and c) taking an image by means of said image taking element (60). The image taking apparatus (1) comprises an image-forming optical system (20); a focussing section (29); a focussed-state detection arrangement (70); an image taking element (60); and a control module (4); wherein said control module (4) is adapted to adjusting said focussing section (29), so as to shift from said first focussing state (A) to said second focussing state (B). An enhanced control of the in-focus state of taken images can be achieved.

  • Patent number: 6967677
    Abstract: A device in the form of a flat matrix of optoelectric transducer elements is mounted in a camera so that the flat matrix is perpendicular to an axis of an imaging beam in the camera and is movable in a pre-selected direction perpendicular to the imaging beam axis by a support apparatus which includes transfer levers that are tiltable about three swivel axes that are parallel and extend perpendicularly to the preselected direction.

  • Patent number: 6812959
    Abstract: An optoelectric transducer arrangement (7b) is moved by being driven and by being controlled by means of cam/curve guides to convert the whole image to be imaged in a still camera despite that said transducer has a sensor surface that is smaller than the image area to be imaged in the image plane (B). The cam/curve arrangement includes four cam disks (15), for example, whereby one cam disk (15a) is driven by a motor. The transducer (7b) rides on a transducer carrier plate (21), which is moved by means of cams (19) on the cam disks (15, 15a). The transducer movement occurs thereby in a translatory manner.

  • Patent number: 6141051
    Abstract: In a still photographic camera, the focal plane is determined by a matrix-like transducer arrangement (7) of optoelectronic sensor elements (9). The viewfinder image is directly generated by evaluation of the electric output signals (e.sub.9) from the transducerelements (9) that form the transducer arrangement (7).
