  • Patent number: 10044912
    Abstract: A short delay time from imaging of an imaging element to displaying on a view finder is realized using a simple circuit configuration. In a live view mode, an image processing circuit performs image processing on imaging data from an image sensor, and generates image data of a display image. When processing for one line ends, progress information is output. When the image data of the display image is able to be output in synchronization with a second horizontal synchronization signal, a timing generator causes a data enable signal to be active, and supplies the image data to a data input unit according to this progress information on the other hand, when the image data is unable to be output, the timing generator causes the data enable signal to be inactive and supplies dummy data to the data input unit.

  • Patent number: 9049434
    Abstract: A 3D imaging device determines during imaging whether the captured images will be viewed three-dimensionally without causing fatigue while simulating actual human perception. In a 3D imaging device, a warning unit provides a warning to a photographer indicating that the captured images of the scene to be imaged will not be perceived as a 3D video having an appropriate 3D effect when a control unit determines that the captured images will not be perceived as such an appropriate 3D video. The 3D imaging device is prevented from obtaining an inappropriate 3D image (3D video).

  • Patent number: 9025051
    Abstract: Various methods are provided for automatically adjusting a zoom feature in accordance with a camera movement to perform a dolly zoom effect. One example method may include causing reception of a first image frame from video data, wherein the first image frame comprises two or more interest points, causing reception of a second image frame from the video data, wherein the second image frame comprises the two or more interest points in a different location, and tracking a difference in location of the two or more interest points from the first image frame to the second image frame. The method may also include calculating a scaling factor and applying the scaling factor to the second image frame.

  • Patent number: 9001234
    Abstract: The invention provides an imager readout architecture utilizing analog-to-digital converters (ADC), the architecture comprising a band-limited sigma delta modulator (SDM) ADC; and a serpentine readout, which can be configured to allow the band-limited SDM to multiplex between multiple columns by avoiding discontinuities at the edges of a row. SDM ADC image reconstruction artifacts are minimized using a modified serpentine read out methodology, the methodology comprising using primary and redundant slices with the serpentine read out in opposite directions and averaging the slices. Advantageously, the invention can be used to develop a read out integrated circuit (ROIC) for strained layer superlattice imagers (SLS) using sigma delta modulator (SDM) based analog to digital converters (SDM ADC).

  • Patent number: 8995018
    Abstract: A color space converter converts data points from one color space to another color space using a lookup table. Color space converters may be used in any device that involves image processing, such as displays and printers. An interface receives an input value in a first color space. A controller access a lookup table stored in memory to determine an upper bound and a lower bound of a subset of the color space. An output value is interpolated between the upper bound and the lower bound using interpolation values. The interpolation values of the last subset in any dimension of the color space are modified by a scale factor to approximate ideal values.

  • Patent number: 8994838
    Abstract: Determining an amount of motion in a second frame of video with reference to a first frame of video. Adaptively predicting a cropping factor for the second frame in response to the determined amount of motion. The cropping factor specifies a portion of the second frame that is to be excluded from the second frame. The predicted cropping factor is adaptively changed for a successive plurality of frames by buffering the first frame to predict a desired cropping factor for the second frame, wherein the first frame occurs prior to the second frame.

  • Patent number: 8994877
    Abstract: A digital camera system synchronizes a flash to an array of image sensing elements. The array of image sensing elements senses an image focused on the array by a lens. The system includes an array controller that implements an electronic rolling shutter to capture the image as a frame. The electronic rolling shutter includes read and reset pointers that the array controller scans through the array to capture integrated photo charges on the image sensing elements to generate the frame. The number of lines between the reset and read pointers defines the integration time of the imager. The system also includes a flash controller that synchronizes the flash to a portion of the frame. When the flash is activated, the camera system reduces the integration time and synchronizes the flash to the scanning of a selected portion of the array.
