    Abstract: The invention provides an image detecting module including a base, a carrier movably disposed on the base, an image detecting unit disposed on the carrier, a contact portion fixed to the carrier, and a fixed member fixed to the base. The fixed member has a protrusion movably contacting a recess of the contact portion. When an external force is exerted on the base and the carrier moves with respect to the base, the protrusion slides on a surface of the recess. When the external force is released, the protrusion slides to the bottom of the recess, such that the carrier is held in a predetermined position with respect to the base.

    Abstract: An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds a threshold. A controller selectively transfers acquired images for storage. A motion extractor determines motion parameters of a selected, stored image. An image re-constructor corrects the selected image with associated motion parameters. A selected plurality of images nominally of the same scene are merged and corrected by the image re-constructor to produce a high quality image of the scene.

  • 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.

  • Patent number: 7760237
    Abstract: An imaging device according to the present invention includes: an image-capturing optical system forming an image of a subject on a surface of an image sensor; a blur-detecting unit detecting a blur of an optical axis in the image-capturing optical system; an image-capturing unit which divides a total exposure time by a predetermined dividing number to repeat image capturing, and generates a number of images corresponding to the dividing number; and a composing unit which finds a motion vector based on the images in the dividing number generated by the image-capturing unit and on the blur detected by the blur-detecting unit and composes the generated images in the dividing number based on the motion vector. Therefore, it is possible to precisely correct a blur while shortening the time required for the blur correction.

  • Publication number: 20100177198
    Abstract: An imaging device capable of detecting and correcting, with high accuracy, the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging without being influenced by the individual variation, temperature characteristic, and variation with time of the sensor. To correct the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging, the result of detection of the angle of inclination of the device by an angle sensor (8a) is corrected with the result of detection of the angle of inclination of the image on the basis of the feature of the captured image by an image inclination detecting section (7), and the imaging device (3) is rotated around the optical axis or an axis parallel to the optical axis according to the corrected angle of inclination of the device.

  • Publication number: 20100177197
    Abstract: An imaging apparatus wherein a captured image is subjected to a rotational transform so as to correct the inclination of one or more subjects in the captured image. The imaging apparatus defines, with reference to a physical inclination detected by a sensor, an angle range in which the image is to be processed. The imaging apparatus then processes the captured image and detects lines therein and inclination angles thereof. The imaging apparatus then creates histograms indicative of frequency distributions of the inclination angles of those lines, and selects, in the created histograms, an inclination angle having a frequency that satisfies a predetermined criterion, as a rotational angle to be used for the rotational transform.

  • Patent number: 7750943
    Abstract: A shooting-information-detecting section detects shooting information from an image pick-up section. A motion-detecting section detects a motion direction of an image on an overall screen based on a motion direction of the image pick-up section contained in the shooting information. A processing-region-setting section sets a processing region in at least any one of a predicted target image and a peripheral image thereof, which correspond to a target pixel in the predicted target image. A processing-coefficient-setting section sets a motion-blur-removing-processing coefficient that corresponds to the motion direction detected in the motion-detecting section. A pixel-value-generating section generates a pixel value that corresponds to the target pixel based on a pixel value of a pixel in the processing region set in the processing-region-setting section and the processing coefficient set in the processing-coefficient-setting section. Motion-blur-removing processing can be accurately performed.

  • Patent number: 7742077
    Abstract: A video image stabilization system includes a camera having an image capturing device capturing a video image. The camera has a selectively adjustable field of view. A processing device is operably coupled to the camera. The processing device receives signals indicative of the field of view of the camera and images captured by the camera. The processing device automatically tracks movements of at least one object in the images. The processing device determines a stabilizing adjustment for the video image as a function of an unintended change in the field of view of the camera during a time interval between capture of a first image and capture of a second image. The determining is based upon the signals indicative of the field of view and an analysis of the first and second images.

    Abstract: Exposed images from a CCD (101) are each captured to Surfaces A, B and C in an SDRAM (103) in a repeated sequence from A, B to C, and the latest image among the images thus captured is displayed. While an image on Surface B is being transferred, an image on Surface A is used as the image to be displayed. The next exposure is started, and images to be displayed are switched, at the same timing as the transfer is started. An image to be displayed on an LCD monitor (1?) is stopped from being updated when camera shake compensating device starts to be released from the mechanical holding. The next switching of images and the transfer of an exposed image from the CCD (101) to the SDRAM 103 are prohibited. When the release of the mechanical holding is completed, the next exposed image is transferred from the CCD (101) to the SDARM (103). Updating is permitted for displaying the image which is transferred to the SDRAM (103) on a display device.

  • Patent number: RE42289
    Abstract: An image system which captures, along with the images, information defining both the position and the orientation of the camera along with the distance to the subject. A video camera is attached to three accelerometers, two gyroscopes, and a rangefinder. Data gathered from these devices and defining the pitch, yaw, and roll of the camera, the camera's acceleration, and the distance to the subject is captured and recorded along with video images. The video images are later stored within a computer's data base along with data defining the position and orientation of the camera and the distance to the subject for each image, this latter data being computed from the captured data. The images may then be presented to the user in a three-dimensional display in which the user can navigate through the images using a joystick device, with the images located in positions corresponding to the positions in space of the objects that were imaged.
