  • Patent number: 8294766
    Abstract: Systems and methods are providing for navigating a three-dimensional model using deterministic movement of an electronic device. An electronic device can load and provide an initial display of a three dimensional model (e.g., of an environment or of an object). As the user moves the electronic device, motion sensing components, positioning circuitry, and other components can detect the device movement and adjust the displayed portion of the three-dimensional model to reflect the movement of the device. By walking with the device in the user's real environment, a user can virtually navigate a representation of a three-dimensional environment. In some embodiments, a user can record an object or environment using an electronic device, and tag the recorded images or video with movement information describing the movement of the device during the recording. The recorded information can then be processed with the movement information to generate a three-dimensional model of the recorded environment or object.

  • Patent number: 8279290
    Abstract: In an image pickup apparatus in which image stabilization is performed based on shake sensor and movement-vector-obtaining method which can perform accurate blur correction since shake components difficult to be detected by shake sensor can be detected by the movement-vector-obtaining method, the image blur due to high frequency vibration such as vehicle vibration cannot be corrected by the movement vector in low-frame-rate shooting since the detectable frequency band narrows in high frequency. Therefore, it is necessary to optimize the combination of blur information from the angular velocity sensor and from the movement vector, according to the frequency band detectable by the movement vector depending on change in frame rate. The combination ratio of blur correction based on blur information from angular velocity sensor, acceleration sensor and blur correction based on movement vector is determined depending on frequency detectable by the movement vector which inevitably changes depending on frame rate.

    Abstract: When sensing an image using an image sensor driven by the rolling shutter method, a shake of an image sensing apparatus in the exposure period of the image sensor is detected, and the temporal characteristic of the detected shake is obtained. For the temporal characteristic of the shake, the frequency distribution of the distortion amount of an object image that is generated in the image owing to the shake is analyzed. For at least the center frequency, the temporal characteristic of the shake is compensated for to eliminate a phase shift generated when the temporal characteristic of the shake is obtained. An object image distortion arising from the shake for each line of the image sensor is corrected using a correction amount calculated from the compensated temporal characteristic of the shake.

  • Patent number: 8218888
    Abstract: Motion blur periods (bf) are detected (14) from gradation differences (g1) between a first image signal (d1) and a second image signal (d2), gradation differences (g2) between the second image signal (d2) and a third image signal (d3), and results of the detection of transition periods (h) in the gradations of the second image signal (d2), and the second image signal (d2) is corrected (3) only during the detected motion blur periods (bf). Transition periods (h) are deemed to occur when, for example, the absolute value of a gradation change in the second image signal is greater than a first predetermined threshold value (S1) and less than a second predetermined threshold value S2 (<S2). Motion blur in the image signal can be detected without increased circuit size, and accordingly, the detected motion blur can be reduced.

  • Patent number: 8208030
    Abstract: Method for motion detection in a current picture (CP) with respect to a reference picture (RP), wherein for a plurality of locations in the current picture (CP) respective difference values (|D|) are determined (B100). A respective difference value is determined based on a difference between a first value and a second value, wherein the first value is descriptive of a photometric measure of one of the locations in the current picture (CP) and the second value is descriptive of the photometric measure of a corresponding location in the reference picture (RP). Based on the difference values, a histogram is determined (B102). The histogram is used as a basis for determining (B104) a threshold (T1, T2, T3). At a respective location in the current picture (CP), motion is detected by comparing the threshold (T1, T2, T3) to the difference value (|D|) of the respective location.

  • Patent number: 8203613
    Abstract: In an image acquisition apparatus, RAW data obtained in image acquisition with an imager in which a color filter is disposed in a front face is divided into each identical color by a RAW data dividing unit, a compression coding processing unit produces coded data of each color by compressing the RAW data at a compression rate controlled for each color, and the coded data of each color is recorded in a recording unit. A motion compensation unit compensates a relative positional relationship between frames by estimating a motion of a subject between frames of plural images, using specific color division coded data which is decoded by the compression coding processing unit and a RAW format data reproducing unit, the specific color division coded data being coded data of a color close to a peak of spectral sensitivity of human vision in the coded data of each color.
