    Abstract: Rotations of a camera around two axes are detected by two gyro sensors. A color temperature of a photographing location is detected by an AWB sensor. One of a plurality of low-pass filters, the cut-off frequency component of which is different, can be connected to one gyro sensor. The low-pass filter which is connected to the gyro sensor, is changed by a transfer switch based on the output result of the AWB sensor, so that a frequency range which is retrieved from the output voltage of the gyro sensor is controlled. With respect to another gyro sensor, a similar operation is carried out. A hand-tremble correcting circuit calculates a driving amount of an image sensor, by which the tremble is canceled, based on the output voltages of the gyro sensors in which a predetermined frequency range was retrieved in accordance with the condition of the photographing location.

When a lens holder and an X slider are moved in the X direction, small balls roll between the side surface of the lens holder and the inner surface of a frame of a Y slider, thereby reducing a sliding load therebetween. When the lens holder and the Y slider are moved in the X direction, small balls roll between the side surface of the lens holder and the inner surface of the frame of the X slider, thereby reducing a sliding load therebetween. Therefore, it is possible to achieve an optical image stabilizer having low power consumption, a smooth operation, and high responsibility. In addition, the thickness of the lens holder is equal to or smaller than the sum of the thicknesses of the X slider and the Y slider overlapped with each other.

    Abstract: The power consumption is reduced by efficiently using C-AF (continuous autofocus). An angular velocity detection circuit calculates angular velocity based on output from a yaw direction angular velocity sensor and a pitch direction angular velocity sensor. Based on the angular velocity, a shake width detection circuit 45 continuously detects the shake amount of the apparatus. If the maximum value of the shake amount during the latest Nms (N milli-seconds) is less than a pre-determined value, it is judged to be a time for shooting operation and the C-AF is operated. If the maximum value of the shake width during the latest Nms is the pre-determined amount or more, it is judged that shooting operation is not being performed and the C-AF is stopped. In this manner, the power consumption can be reduced by operating the C-AF only as needed.

  • Patent number: 7428375
    Abstract: Auto-focus in a digital camera is improved by stabilizing successive images. Each auto-focus image is correlated to previous images so that scene movement or motion can be tracked. The area in the scene where focus figure-of-merit is computed is adjusted according to the amount of scene movement. Also, two separate focus frames may be compared to determine the direction and speed of the motion. This improves the accuracy of the focus figure-of-merit which results in fewer autofocus failures.

  • Patent number: 7400824
    Abstract: An anti-shake apparatus includes a movable unit supported by a fixed unit and movable in first and second directions as well as rotated on a movable plane. A first and second driving unit supply driving forces to the movable unit in a first direction. A third and fourth driving unit supply driving forces to the movable unit in a second direction. A first detector detects a direction of a gravitational force acting on the movable unit. A second detector detects a rotational movement around a straight line perpendicular to the movable plane. A control unit controls the third and fourth driving forces to correct the rotational movement when the gravitational direction is parallel to the first direction. The control unit controls the first and second driving forces to correct the rotational movement when the gravitational direction is parallel to the second direction.

  • Publication number: 20080136931
    Abstract: In an imaging device that generates a correction image by performing, on the basis of shake information on a target image, shake correction processing on the target image when a correction instruction is issued by a user while the target image is displayed on a display unit, and that displays the corrected image on the display unit, preceding correction performs the shake correction processing before the issuing of the correction instruction. To suppress an increase in power consumption, due to the preceding correction, however, the preceding correction is not performed when the amount of camera shake of a target image is determined to be too small by referring to the amount of shake of a target image. Moreover, the frequency of the issuing of correction instructions for a target image in the past is referenced, and in a case where the frequency is low, the preceding correction is not performed.

  • Patent number: 7340160
    Abstract: Disclosed is an imaging apparatus capable of realizing a camera shake correction function while reducing the size and power consumption of the apparatus without deteriorating the use efficiency of an image sensor thereof. An imaging device has photoelectric conversion elements arranged two-dimensionally and a transfer path for transferring electric charge converted by the photoelectric conversion element. A motion detection unit detects motion of the apparatus according to timing pulses generated by a time management circuit at shorter intervals than exposure time. A drive circuit transfers the electric charge previously read onto the transfer path for a predetermined distance according to the detected motion. Electric charge newly read out and converted by the photoelectric conversion elements at the intervals of the timing pulses is added to the previous electric charge which has been transferred on transfer path.

  • Publication number: 20080044170
    Abstract: An image capturing system capable of providing an optimal exposure setting and method of operating the same are disclosed. The image capturing system includes a CMOS image sensor having photosensitive cells; a lens module having a mechanical shutter; a memory having a program for exposure analysis and a program for detecting motion stored therein; and a controller having a processor. The processor is configured to execute the program for exposure analysis and the program for detecting motion. The exposure analysis includes determining the exposure time for capturing an image of a scene based on the brightness of the scene and comparing the exposure time with the closing time of the mechanical shutter. The controller is operable to set the image capturing system to either a “Global-Reset mode” or an “Electronic-Rolling-Shutter” (ERS) mode based on the output of the exposure analysis and motion detection.

  • Patent number: 7298398
    Abstract: The present invention provides a technique capable of changing the image capturing direction of a camera at high speed while suppressing noise generated by resonance. At the time of changing the angle of the image capturing direction of a surveillance camera from a base angle to a first angle, if driving of both of a motor for panning and a motor for tilting is simply started simultaneously and completed simultaneously, there is a case such that the motor for panning generates resonance with the body of the surveillance camera or the like and noise becomes too loud. In such a case, the drive speed of the motor for panning, that is, the pulse rate is shifted to a high speed side on which resonance does not generate and the panning is finished first. Specifically, the angle of the image capturing direction is changed from the base angle to a second angle and, after that, changed from the second angle to the first angle.
