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.

The amount of parallax of a 3D image can be adjusted by intuitive operation. A zoom lever is thrown to telephoto side to cause the graphic processing unit to generate images for the left eye and the right eye adjusted such that a position where a component is drawn is far from a center line and the zoom lever is thrown to wide angle side to cause the graphic processing unit to generate images for the left eye and the right eye adjusted such that the position where the component is drawn is near the center line.

An image synthesis method includes a placement information obtaining step of obtaining placement information about a plurality of images in which adjacent images have a common subject region, and a synthesis step of combining the images using a mapping mode in accordance with the placement information. Prior to performing mapping transformation of the input images, coordinate-space transformation parameters for transforming the coordinate space of one image among the images into the coordinate space of another image are generated. The images are combined based on a given mapping mode and the coordinate-space transformation parameters.

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&#x2212;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.

Images sensed through object lensesR andL, having zoom lenses, with image sensorsR andL are processed by image signal processorsR andL, 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, 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 sensorsR andL and that they fall within the both focal depths of the image sensorsR andL.
