  • Patent number: 7791644
    Abstract: When a camera body is shaken, a piezoelectric element generates a signal corresponding to angular velocity. The output signal of the element is amplified by a synchronous detection amplifier and is sent to a high-pass filter. An output signal of the filter is integrated after digital conversion and is outputted as a shake amount of the camera body. An initialization-trigger generating circuit generates an initialization trigger in predetermined cycles. When the trigger is inputted, the amplifier outputs a first zero-level signal. A zero-level initialization circuit initializes the filter every input of the trigger to output a second zero-level signal. The two zero-level signals have a reference signal value to be outputted at a time of the angular velocity zero. During the initialization, the reference signal value is applied to both sides of the filter to remove drift components included in the output signal thereof.

  • Publication number: 20100086290
    Abstract: An image pickup apparatus which is capable of achieving excellent moving image shooting even when strobe popup is not successfully performed during moving image shooting. A camera implementing the image pickup apparatus has a strobe that shifts between a retracted position and a service position. When a motor for operating the camera performs reverse rotation, the strobe is driven to the service position. An MPU instructs the motor to drive the strobe to the service position, and determines, based on a signal from a popup position-detecting switch, whether or not the strobe has been normally driven to the service position. When the strobe has not been normally driven to the service position, the MPU performs error handling. The error handling is carried out differently between a case where moving image shooting is being performed and a case where the moving image shooting is not being performed.

  • Patent number: 7693342
    Abstract: An evaluating method of image information acquires image information, performs camera shake evaluation of the image information by determining a camera shake direction on the basis of the image information, and performs out-of-focus evaluation of the image information by using information concerning a camera shake direction determined in the camera shake evaluation.

  • Patent number: 7683936
    Abstract: An angular-velocity detector includes a first sensor, a second sensor, and a controller. The first sensor is used for detecting motion around an axis of a second direction perpendicular to a first direction. The second sensor is used for detecting motion around an axis of the first direction. The controller performs an operation that corrects an output error caused by an angle of inclination of the second sensor by using a first correction coefficient that is a ratio of a second amplitude to a first amplitude. The first amplitude is amplitude of output value from the first sensor when the angular-velocity detector is in first motion around an axis of the second direction without second motion around an axis of the first direction. The second amplitude is amplitude of output value from the second sensor when the angular-velocity detector is in the first motion without the second motion.

  • Patent number: 7680403
    Abstract: In order to efficiently remove dust, an image pick up apparatus is provided with an image sensor for acquiring subject images via a photographing lens, a shift mechanism, holding the image sensor, capable of moving the image sensor in a first direction orthogonal to the optical axis of the photographing lens, and in a second direction that is different from the first direction, a sensor arranged in front of the image sensor, for detecting vibration applied to the optical element that is displaced by the shift mechanism together with the image sensor, and a controller for driving the shift mechanism according to output of the sensor for detecting vibration when operation is carried out to prevent image shake due to vibration applied to the image pickup apparatus, and moving the shift mechanism in accordance with a specified pattern regardless of sensor output when carrying out a dust removal operation for removing dust that has become attached to the surface of the optical element.

  • Patent number: 7675543
    Abstract: Segments of interest within video footage are identified automatically. Such segments of interest include portions of the footage which were taken using a hand held camera and which show a static subject, portions which track the motion of a moving subject, and portions which show an abrupt event. Methods are presented for identifying such segments, based on motion and/or color analysis of the video footage or based on observations of discontinuities in the video footage following a period of stability.

  • Patent number: 7639932
    Abstract: An optical apparatus detects the moving velocity of a main object on an imaging plane and computes the moving velocity of the main object on the basis of the difference between the detected moving velocity on the imaging plane and the velocity of a panning shot captured by a user. During exposure, the optical apparatus detects the difference between the computed moving velocity of the main object and the panning-shot velocity, that is, an error of the panning-shot velocity, and decenters the optical axis of an imaging lens so as to correct the error, thereby enabling the user to capture a satisfactory panning shot.

  • Patent number: 7623775
    Abstract: Maximum and minimum aperture sizes are regulated with regard to a diaphragm in order to secure predetermined optical capability in an optical unit which includes a taking lens and the diaphragm. In a normal taking, the diaphragm is used within a normal taking range from the maximum to the minimum aperture sizes. In the present invention, an aperture size which is larger than the maximum size and a size which is smaller than the minimum size (extra aperture size or extra small size) are respectively set at outside the range that secures the capability. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure (AE) adjustment, auto focus (AF) adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels.
