摘要： 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.

摘要： In a stereoscopic image imaging method which captures an image of an object to be displayed as a stereoscopic image, a three-dimensional image is generated in real time from multi-viewpoint images captured by a multi-camera, and is displayed on a viewer provided to the multi-camera, thus allowing a photographer to adjust an imaging condition. The photographer is informed of parameters, which implements a display state adjusted by an observer of a three-dimensional display while observing the three-dimensional image, via the viewer, and the photographer can capture appropriate multi-viewpoint images.

摘要： An image processing system according to an embodiment includes a stereoscopic display device, a transform unit, an image generating unit, and a display control unit. The transform unit reduces or enlarges volume data which is three-dimensional (3D) image data such that among scales of a stereoscopic image assumed to be displayed on the stereoscopic display device using a parallax image group obtained from the volume data, a scale in a depth direction on a display surface of the stereoscopic display device is substantially the same as a scale in another direction which is a direction other than the depth direction. The image generating unit generates a parallax image group by performing a rendering process on transformed volume data. The display control unit causes the parallax image group to be displayed on the stereoscopic display device.
