  • Patent number: 11012615
    Abstract: A digital camera includes a detection unit, an operation history storage unit, an analysis unit, a determination unit, and a warning unit. The detection unit detects an imaging operation and a setting operation of a user as user operation information. The setting operation is an operation to set setting information of a first setting item and setting information of a second setting item selectable exclusively with respect to the setting information of the first setting item for setting items relating to imaging conditions. The analysis unit acquires normal operation information based on an imaging operation history and a setting operation history stored in the operation history storage unit. After the normal operation information is acquired, in a case where the user operation information is different from the normal operation information, the determination unit determines that the user is in the confused state. The warning unit issues a warning in a case where determination is made to be the confused state.

  • Patent number: 10931869
    Abstract: A digital camera includes a rear display unit, an imaging optical system, an operation button, a touch panel, a shutter unit, an imaging element, a main control unit, a digital signal processing unit, and a setting information storage unit. After setting information is set in a first setting item and a second setting item of an imaging condition, in a case where the setting information of the first setting item is changed through the touch panel, the main control unit changes the setting information of the second setting item to setting information according to the setting information of the first setting item after the change. When determination is made that a specific setting operation is performed, the main control unit reads the setting information of the first setting item and the second setting item from the setting information storage unit and restores the setting information to the setting information before the change.

  • Patent number: 10924653
    Abstract: In a case where a user sets an imaging condition setting rule based on a setting menu (M), a setting item of the imaging condition setting rule is selected from among a plurality of setting items. In a case where the setting item of the imaging condition setting rule is selected, a selection candidate list of an imaging condition setting rule having selection candidates “ALL FIRST-WIN”, “ALL LATE-WIN”, and “MIXED” is displayed. In a case where “ALL FIRST-WIN” is selected, a first-win processing unit is executed in all combinations of two setting items. In a case where “ALL LATE-WIN” is selected, a late-win processing unit is executed in all combinations of two setting items. Then, in a case where “MIXED” is selected, a mixed state is brought in which a combination, in which the first-win processing unit is executed, and a combination, in which the late-win processing unit is executed, are mixed.

  • Patent number: 8976232
    Abstract: A distance determining section increases a convergence point distance by a distance proportionate to an operation of an up key. The distance determining section reduces the convergence point distance by a distance proportionate to an operation of a down key. A target convergence point distance is incremented by 1 m per pressing operation of the up key. The target convergence point distance is decremented by 1 m per pressing operation of the down key. A shift amount setting section converts the target convergence point distance into a shift amount that corresponds to the target convergence point distance. The shift amount is set to an image shifting section. The image shifting section shifts each cut out region by the shift amount from a reference position and cuts out viewpoint images with the cut out regions from original left and right viewpoint images. Thus, the parallax-adjusted viewpoint images are produced.

  • Patent number: 7848626
    Abstract: A shake detection technique which does not mistakenly detect a swing-back component at the end of panning as a shake is provided. A shake detection apparatus includes: a sensor which detects velocity or angular velocity; a high-pass filter which removes a low-frequency component from an output signal of the sensor; a shake detection device which detects shake of an apparatus body based on an output signal from the high-pass filter; a determination device which determines whether the output signal of the high-pass filter contains a swing-back component outputted when a shake continued in one direction stops; and a removal device which removes the swing-back component from the output signal of the high-pass filter based on a determination result of the determination device.

  • Publication number: 20050018059
    Abstract: A high sensitive image signal output from a main pixel and a low sensitive image signal output from a sub pixel are input to an image signal processing circuit. A composite parameter which is changed in response to setting conditions of image quality is input to an image composite processor from a system controller. The image composite processor generates a composed image signal by composing the high and low sensitive image signals based on the composite ratio designated by the composite parameter.
