The present disclosure pertains to an encoding device and encoding method, and a decoding device and decoding method which make it possible to obtain depth image data and two-dimensional image data for a viewpoint that corresponds to a prescribed display image generation method, regardless of the viewpoint at the time of image capture From three-dimensional data of an imaging subject generated from two-dimensional image data for a plurality of viewpoints, a conversion unit generates two-dimensional image data for a plurality of viewpoints that correspond to the prescribed display image generation method, and generates depth image data expressing the location in the depth direction of the imaging subject for each pixel An encoding unit encodes the depth image data and two-dimensional image data generated by the conversion unit A transmission unit transmits the depth image data and two-dimensional image data encoded by the encoding unit This disclosure is applicable, for example, to an encoding device or the like

Encoding device and encoding method, and decoding device and decoding method

In the present invention, when a 3D medical image is displayed on a 3D display, the position of accompanying information displayed at the same time is appropriately controlled. The position of the accompanying information in the coordinate system of a 3D signal value that is an item to be drawn is computed, and said position is saved in a storage unit. By integrating a 3D data area and an accompanying information area, a drawing process unit generates an output image to be displayed in a display unit, said 3D data area being drawn for an area specified by mask information that specifies an area to be drawn among an array of the 3D signal value that is the item to be drawn, and being drawn on the basis of information that specifies a drawing method for a 2D image based on the 3D signal value array, and said accompanying information area being drawn for the accompanying information, which is associated with the item to be drawn, and being drawn on the basis of position information for the accompanying information determined by a drawing control unit. The display unit displays the drawn output image.

Image display device, method and program

A hand-held information processing terminal includes a display, a camera arranged in proximity to the display and capable of obtaining an image of a user including infrared components, an estimation module that estimates relative positional relation between the display and the user based on the obtained image, a generation module that generates a plurality of display images in accordance with the relative positional relation, and a control module that provides stereoscopic display to the user in accordance with a position thereof with the use of the plurality of display images.

An information processing apparatus generates rendered images associated with 3D representations of an object indicated by image groups each including a plurality of parts of 2D images by using the image group to perform at least one of movement and deformation of each part included in the image groups. At this time, the apparatus sequentially decides rendering directions in which the object is rendered in the rendered images, and determines a moving direction determined by transition of the sequentially decided rendering directions. The apparatus differentiates the rendering direction, in which at least some parts of the image groups used to generate the rendered images are changed to different parts, in accordance with the determined moving direction.

Recording medium, information processing apparatus, and control method

PROBLEM TO BE SOLVED: To realize favorable stereovision in various display environments.SOLUTION: Mobile communication terminals 110, 130 are computers such as portable telephones capable of performing telephone conversations and data communication, so as to perform the telephone conversations and the data communication with another mobile communication terminal 10 or perform the data communication with an image data conversion device 120 via a mobile communication network 100. The image data conversion device 120 is a computer such as a server device capable of performing the data communication, so as to perform image data conversion processing to attain stereovision. At that time, the image data conversion device 120 specifies the model of the mobile communication terminal 130 and performs the image data conversion processing corresponding to its display environment. Consequently, the favorable stereovision is realized in the display environment of the mobile communication terminal 130.
