  • Publication number: 20180332214
    Abstract: There is provided an image processing apparatus. A focal position determining unit determines, for each of a plurality of captured image data, a focal position in a depth direction at a target position. The focal position determining unit determines a position at which a subject at the target position is in focus as the focal position if a first focus mode has been selected by a selecting unit, and determines the focal position for each of the plurality of captured image data such that the focal positions track a position at which a subject at the target position is in focus at a speed that is less than or equal to a threshold value, in an order of generation of the plurality of captured image data, if a second focus mode has been selected by the selecting unit.

  • Publication number: 20120287246
    Abstract: An image processing apparatus capable of appropriately displaying a face frame in a manner superimposed on a three-dimensional video image. In a three-dimensional photography image pickup apparatus as the image processing apparatus, two video images are acquired by shooting an object, and a face area is detected in each of the two video images. The face area detected in one of the two video images and the face area detected in the other video image are associated with each other. The three-dimensional photography image pickup apparatus generates face area-related information including positions on a display panel where face area images are to be displayed. The face area images are generated according to the face area-related information. The two video images are combined with the respective face area images, and the combined video images are output to the display panel.

  • Patent number: 7289579
    Abstract: An apparatus is provided in which a parameter of Viterbi decoding is adjusted on the basis of a metric difference for evaluation of PRML signal quality to increase the error rate even when using a medium on which recording is performed under a large-distortion condition. When a reproduced signal is binarized by maximum likelihood decoding such that a state transition sequence most probable to be correct of m kinds of state transition sequences from a first state at time n?1 to a second state at time n is selected, a metric difference between the most probable state transition sequence and a second most probable state transition sequence at a predetermined time is computed, and a parameter (a reference amplitude value or a metric) of a maximum likelihood decoder is corrected on the basis of the metric difference to optimize maximum likelihood decoding operation.

  • Patent number: 7164786
    Abstract: Images sensed through object lenses 100R and 100L, having zoom lenses, with image sensors 102R and 102L are processed by image signal processors 104R and 104L, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor 220, where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensors 102R and 102L and that they fall within the both focal depths of the image sensors 102R and 102L.
