There is provided an encoding apparatus, an encoding method, a decoding apparatus, and a decoding method that make it possible to acquire two-dimensional image data of a viewpoint corresponding to a predetermined display image generation method and depth image data without depending upon the viewpoint upon image pickup. A conversion unit generates, from three-dimensional data of an image pickup object, two-dimensional image data of a plurality of viewpoints corresponding to a predetermined display image generation method and depth image data indicative of a position of each of pixels in a depthwise direction of the image pickup object. An encoding unit encodes the two-dimensional image data and the depth image data generated by the conversion unit. A transmission unit transmits the two-dimensional image data and the depth image data encoded by the encoding unit. The present disclosure can be applied, for example, to an encoding apparatus and so forth.

This patent provides a method and apparatus for acquiring imagery with improve spatial resolution through an apparatus called a “light painting imaging device”. Other aspects of this invention correct for barrel distortion and pincushion distortion.

Systems and techniques are provided for camera synchronization. An example method can include determining, for each camera of a plurality of cameras, a common point within an exposure time corresponding to a frame being requested from each camera.

An image processing apparatus that performs processing concerning the display of a stereoscopic image so as to improve the convenience of a user in viewing a stereoscopic image. A head mount display displays a stereoscopic image using image data including a plurality of images having different viewpoints. The image data is processed based on metadata attached to the image data. In a case where information indicating that the image data is associated with a file format which cannot cause the head mount display to perform display is included in the metadata, the image data is converted into a file format which can cause the head mount display to perform display.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.
