20090079761 | APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCT FOR RENDERING MULTI-VIEWPOINT IMAGES - For each of rendering programs in each of which a rendering procedure is described, a piece of shape data indicating a shape of a rendering target object serving as a rendering target is specified, and also information related to viewpoint positions that are different from one another is specified as a rendering condition that is used when the rendering program is executed. A multi-viewpoint image that is obtained by rendering a rendering target object with respect to each of the viewpoint positions is generated by sequentially rendering, in correspondence with execution of each of the rendering programs, images of the rendering target object to be rendered by using the rendering program, while the viewpoint is changed one after another. | 03-26-2009 |
20090096786 | APPARATUS OF AND METHOD FOR DRAWING GRAPHICS, AND COMPUTER PROGRAM PRODUCT - An apparatus of drawing graphics includes an edge coefficient calculator calculating, from vertex data on vertices of a triangle, edge coefficients of edge functions used to determine whether a pixel is present in an inside region of the triangle, and a bounding box calculator calculating a bounding box of projected images of the triangle on a projection plane based on the edge coefficients. The apparatus also includes a starting point determiner and a traverser. The starting point determiner classifies the projected images of the triangle based on a combination of the edge coefficients for respective sides of the triangle, and determines a scan starting point from a corner of the bounding box based on classification of the projected images. The traverser generates pixel data used in rasterization by scanning the bounding box from the scan starting point. | 04-16-2009 |

20120268455 | IMAGE PROCESSING APPARATUS AND METHOD - An image processing apparatus according to an embodiment includes a displaying device, a receiver, a calculator, and a controller. The displaying device can display a stereoscopic image. The receiver receives a start signal used for starting setting a viewing zone in which the stereoscopic image can be viewed by a viewer. The calculator calculates, on the basis of position information of the viewer, viewing zone information representing a position of the viewing zone when the start signal is received. The controller controls the displaying device so as to set the viewing zone corresponding to the viewing zone information. | 10-25-2012 |
20130257870 | IMAGE PROCESSING APPARATUS, STEREOSCOPIC IMAGE DISPLAY APPARATUS, IMAGE PROCESSING METHOD AND COMPUTER PROGRAM PRODUCT - According to an embodiment, an image processing apparatus includes an acquiring unit configured to acquire volume data of a three-dimensional image; and a superimposed image generating unit configured to generate a superimposed image that is made by superimposing light information on a depth image when a parallax image obtained by rendering the volume data from multiple viewpoints is displayed as a stereoscopic image. The light information represents a relationship between a position in a depth direction of the stereoscopic image and resolution of the stereoscopic image. The depth image is obtained by rendering the volume data from a depth viewpoint at which the entire volume data in the depth direction is viewable. | 10-03-2013 |
