  • Publication number: 20150254891
    Abstract: Thresholds b1, b2, b3, and b4 are set in the luminance of a raw image. In an image 84a of the lowermost layer, the region in which the luminance is equal to or higher than b1 is left. In an image 84b over it, the region in which the luminance is equal to or higher than b2 is left. In an image 84c over it, the region in which the luminance is equal to or higher than b3 is left. In an image 84d of the uppermost layer, the region in which the luminance is equal to or higher than b4 is left. In each of these images, the alpha value of the other region is set to 0. The images are integrated with the color information of the raw image to generate final slice images. A display image is generated by stacking the generated slice images sequentially from the lowermost layer at predetermined intervals and performing drawing according to the point of sight.

  • Publication number: 20140306952
    Abstract: In an image processing apparatus, a sensor output data acquisition unit acquires data of layered image information from a sensor group. A slice image generation unit generates data of a two-dimensional image for each slice plane surfaces in which distribution is acquired. An image axis conversion unit generates similar data of a two-dimensional image for a plurality of plane surfaces that are perpendicular to an axis different from a sensor axis. A slice image management unit of a display processing unit manages a slice image that is used for drawing according to the position of a viewpoint or the like. Memory for drawing sequentially stores data of an image necessary for drawing. An additional object image storage unit stores image data of an object that is additionally displayed such as a cursor or the like. An image drawing unit draws a three-dimensional object using data of the slice image.

A digital video signal output from the Vout terminal is provided to a display device via a HDMI. The first GPU and a second GPU are connected to each other via a data bus for bidirectional data exchange. The second GPU applies a predetermined rendering process on data provided from the first GPU via a data input and output interface. The rendered data is returned to the first GPU via the data input and output interface. The first GPU processes the data returned from the second GPU as necessary and outputs a digital video signal via the Vout terminal and the HDMI.

  • Patent number: 8559798
    Abstract: A rendering process for rendering an image frame and a postprocess for adapting the image frame to a display are separated. A rendering processing unit 42 generates an image frame sequence by performing rendering at a predetermined frame rate regardless of a condition that the image frame should meet for output to the display. A postprocessing unit 50 subjects the image frame sequence generated by the rendering processing unit to a merge process so as to generate and output an updated image frame sequence that meets the condition. Since the rendering process and the postprocess are separated, the image frame sequence can be generated regardless of the specification of the display such as resolution and frame rate of the display.

  • Publication number: 20120121496
    Abstract: A hydrazine-fixing group such as a ketone group, a formyl group, a chlormethyl group or an amide group, which is capable of releasably fixing hydrazine, is introduced into a side chain of a synthetic resin, and hydrazine is fixed to the hydrazine-fixing group. Since a hydrazine storage resin of the present invention has a hydrazine-releasable group capable of releasing hydrazine, it is able to store hydrazine stably. In addition, hydrazine can be supplied by releasing hydrazine from the hydrazine-releasable group. Consequently, the hydrazine storage resin can be widely used in various industrial fields requiring supply of hydrazine.
