  • Patent number: 7813631
    Abstract: In an image-taking apparatus, a main CPU reads a sensitivity level that has been set, thereby determining whether a subject distance measured in AF processing is longer as compared to a threshold. The threshold is variable such that the higher the sensitivity level is the longer the threshold is. When the main CPU determines that the subject distance is longer as compared to the threshold, a metering/distance-measuring CPU causes a first light emitter having a xenon tube to emit light in response to an instruction from the main CPU. When the main CPU determines that the subject distance is shorter as compared to the threshold, the metering/distance-measuring CPU causes a second light emitter having an LED to emit light in response to an instruction from the main CPU.

  • Patent number: 7808532
    Abstract: A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash. A second image is taken of the same subject matter with the use of flash. The foreground information in the flash image is illuminated by the flash to a much greater extent than the background information. Based on this property, the strategy applies processing to extract the foreground information from the background information. The strategy supplements the flash information by also taking into consideration motion information and color information.

  • Patent number: 7697038
    Abstract: An imaging apparatus comprises an image sensing unit in which a plurality of photoelectric conversion elements are arranged on an image sensing plane, and a control unit. The control unit has a first mode in which image signals are read out from a first photoelectric conversion element group arranged in a first region of the image sensing plane, and a second mode in which image signals are read out from a second photoelectric conversion element group arranged in a second region that is smaller than the first region of the image sensing plane In addition, the control unit performs control such that a readout period of a line arranged on the image sensing plane in the first mode is substantially equal to that of a line arranged on the image sensing plane in the second mode when switching between the two modes.

  • Patent number: 7697062
    Abstract: The present invention relates to a method in a camera for determining a camera setting when using pulsed flash is provided. The camera comprises a source of light. The source of light is adapted to emit light to illuminate an object. The object is further illuminated by ambient light. The method comprises the steps of: Capturing a first image data of the object when the object is illuminated by light emitted by the source of light and by the ambient light, capturing a second image data of the same object when the object is illuminated by the ambient light but not by light from the source of light, creating a difference image data by subtracting the second image data from the first image data. The method comprises the further step of determine a camera setting based on the created difference image data. The determined camera setting is to be used when capturing a third image of the object, using emitted pulsed flash by the source of light to illuminate the object.

    Abstract: The invention provides a greeting card having provided therein an imaging device, the imaging device being configured to capture an image, the capture of an image being controlled by operation of an activation means and a detection means. The activation means being operable on the detection means and is switchable by a user between a non-activated mode, and an activated mode. On adoption of the activated mode, a subsequent detection of the occurrence of a preset event by the detection means effects a corresponding issuance of a trigger signal, the trigger signal causing the capture of the image by the imaging device.
