    Abstract: A focus detection device includes an imaging element, a storage controller, and a focus detector. The imaging element is provided on a light path of a light flux incident via an optical system and has a plurality of pixels of charge storage type two-dimensionally arranged. The storage controller controls to sequentially store charges in pixels arranged in a first direction among the plurality of pixels and controls to sequentially store charges in pixels arranged in a second direction opposite to the first direction. The focus detector detects a focus adjustment state of the optical system based on a first output obtained when the storage controller sequentially performs storage control in the first direction and a second output obtained when the storage controller sequentially performs storage control in the second direction.

  • Patent number: 7495692
    Abstract: In an image processing device such as an electronic camera having a detecting section which detects blurring of an image (movement of the image) picked up by an imaging element, a part of evaluation or calculation required for controls (AF, AE, AWB, etc.) is performed in parallel with the detection of the blurring of the image in order to speed up the controls. After completing the detection of the image blurring, an influence of the blurring is corrected to perform final calculation. In this case, an image area as a calculation object can be limited to raise a processing efficiency.

  • Publication number: 20090027544
    Abstract: Methods and systems for capturing an image. Light is received through an imaging lens that has an adjustable focal center. A motion vector representing motion of the imaging lens is estimated and a shift vector is estimated in response to the motion vector. The shift vector is converted into a voltage gradient and provided to the imaging lens. The voltage gradient shifts the focal center of the imaging lens to compensate for the motion of the imaging lens.

    Abstract: Methods and apparatus for accurately auto focusing a lens of an imaging device. The method includes the steps of focusing an image of a subject on an imager, determining that the subject has moved, and refocusing the image of the subject on the imager by comparing a first brightness of a first scene captured before determining that the subject has moved and a second brightness of a second scene captured after determining that the subject has moved. The first brightness and second brightness are provided with the assistance of a light source.

  • 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: 7423686
    Abstract: To track a region of interest (“ROI”) such as, for example, in a viewfinder of a camera, both the location and distance of a point in the ROI are estimated for a time in the future, based on actual measurements of locations and distances of the point at the present and in the past. Focus is controlled so as to focus on the point of interest based on the estimate of the future location and distance.

  • Patent number: RE42555
    Abstract: A digital-camera processor receives mono-color digital pixels from an image sensor. Each mono-color pixel is red, blue, or green. The stream of pixels from the sensor has alternating green and red pixels on odd lines, and blue and green pixels on even lines in a Bayer pattern. Each mono-color pixel is white balanced by multiplying with a gain determined in a previous frame and then stored in a line buffer. A horizontal interpolator receives an array of pixels from the line buffer. The horizontal interpolator generates missing color values by interpolation within horizontal lines in the array. The intermediate results from the horizontal interpolator are stored in a column buffer, and represent one column of pixels from the line buffer. A vertical interpolator generates the final RGB value for the pixel in the middle of the column register by vertical interpolation. The RGB values are converted to YUV. The vertical interpolator also generates green values for pixels above and below the middle pixel.
