  • Patent number: 6816678
    Abstract: The present invention is in the photographic field, and is used to measure sensitometric characteristics of a photographic element. The present invention relates more particularly to a method that enables the production of a sensitometric control patch with exposure gradient, placed on a photographic element, and enables the measurement of the sensitometric characteristics of the photographic element. The sensitometric control patch is produced so as to obtain on the exposed photographic film strip, a single sensitometric control comprising a gradient of exposure areas, and enables all the sensitometric characteristics of the film to be obtained. The sensitometric control patch is produced from the nominal sensitometric characteristics of the film, and the instantaneous speed of relative movement of the film in front of the light energy source. The present invention has its application in the photography field and in particular the motion picture field.

  • Patent number: 6809792
    Abstract: An apparatus and method for forming a substantially invisible watermark or copy-deterrent pattern within a motion picture frame that utilizes spectral image data in order to apply a pattern that is not objectionable to a viewer, but that can be sensed and recorded by a video camera device. A digital watermark or copy deterrent pattern, message, animation, or obscuring effect can be formed to identify a legally distributed copy, degrade the quality of an illegally recorded copy, or expand the storage requirements for an illegally recorded copy using this technique. The pattern is applied using some combination of UV and IR light sources just outside the visible range, displayed on the movie screen. An illegally recorded copy may bear a visible watermark or copy-deterrent pattern which can be detected upon playback. A copy-deterrent pattern can also be used to make video compression techniques less effective, requiring that an illegally recorded copy require excessive amounts of storage media.

    Abstract: In one aspect, an imaging system is provided. The imaging system has a taking lens unit adapted to focus light from a scene, and a beam splitter receiving light from the scene with a portion of the received light traveling from the beam splitter to a first imaging surface and a portion of the received light traveling from the beam splitter to a second imaging surface. A first image capture system is provided for capturing an image based upon the light traveling to the first imaging surface, and a second image capture system is provided for capturing a second image based upon the image formed at the second imaging surface. An array of micro-lenses is in optical association with the first imaging surface, with each micro-lens in the array concentrating a first fraction of the light from the beam splitter onto concentrated image areas of the first imaging surface. Wherein the first image capture system forms an image based upon the light concentrated onto the concentrated image areas.

  • Patent number: 6801718
    Abstract: Modes of a camera are classified into groups according to their type. On an LCD panel, the different groups are displayed on different rows, and modes to be selected out of each group are displayed in different columns. Group selection is accomplished by vertically manipulating a selector button, and mode selection out of each group is accomplished by laterally manipulating the selector button. This makes possible displaying of selectable modes classified by group on the LCD panel in a way perceivable at a glance. Furthermore, the choice of a group and that of a mode within each group are matched in the mode display arrangement to facilitate the operation for mode selection.

  • Patent number: 6801716
    Abstract: A flash control device comprises a distance input part, a calculating part, and an emission control part. When an electronic flash device is in an FP flash mode, the calculating part calculates a proper flash intensity according to an object distance, an f-number, and sensitivity, the f-number and the sensitivity of a camera. When the electronic flash device is in a discrete flash mode, the calculating part calculates a proper flash intensity according to an object distance, an f-number, and the sensitivity. The emission control part instructs the electronic flash device to flash with a proper flash intensity. The flash control device controls flashing so that the object is illuminated with a proper exposure amount.

  • Patent number: 6798986
    Abstract: In the present invention, slave light emissions are controlled in such a manner that a flash light amount ratio between master and slave flash lights during pre-flash is caused to be approximately equal to a flash light amount ratio between master and slave flash lights during main flash. In another aspect of the present invention, the slave light emissions are controlled in such a manner that a flash time ratio between master and slave flash lights during pre-flash is caused to be approximately equal to a flash time ratio between master and slave flash lights during main flash. Such a control over the slave light emissions realizes a flash illumination having an appropriate amount of light.

  • Patent number: 6788889
    Abstract: In multi-point distance measurement, the distance of a distance measurement object is three-way divided into a very short distance range, a short distance range and a moderate to long distance range, and if the distance of an object located at a very short distance is measured in any one of the endmost distance measurement areas of a plurality of distance measurement areas, and all the distances measured in other distance measurement areas belong to the moderate to long distance, the distance belonging to the very short distance range is not employed, and the shortest distance of distances belonging to the moderate to long distance range is employed as a measured distance. On the other hand, if any of the distances measured in other distance measurement areas belongs to the short distance range which is closer than the moderate to long distance range, the distance belonging to the very short distance range is employed, thereby reducing the frequency of erroneous distance measurement.
