  • Patent number: 8217933
    Abstract: A collision target map and a collision target LUT are generated for each pixel to be subjected to rendering as collision target information with recorded identification information for CG data rendering on the pixel, while carrying out rendering of colliding object group CG data. Then, collision target information corresponding to a rendering pixel is referenced while carrying out rendering of collided object group CG data. In a case in which the colliding object group CG data is contained in the collision target information, it is determined that collision detection should be carried out for a virtual object being rendered, and collision detection information is generated. Such collision detection information allows collision between virtual objects to be detected at high speed.

  • Patent number: 8212916
    Abstract: An image display device that is capable of checking a focusing operation at the time of shooting by a user easily even if a small-sized monitor is used. A luminance-signal extracting unit extracts a luminance signal from a video signal. An amplitude change calculating unit calculates an amplitude change component of the luminance signal extracted. An edge-signal extracting unit extracts an edge signal from the luminance signal extracted. An amplitude calculating unit calculates an amplitude of the edge signal extracted. An amplitude-ratio calculating unit calculates a ratio of the amplitude of the edge signal to the amplitude change component of the luminance signal. A color conversion unit converts the edge signal to add colors according to the calculation result. An adder unit adds the color-converted edge signal and the luminance signal. A display unit displays the video signal to which the color-converted edge signal is added.

  • Patent number: 8212896
    Abstract: An image capturing apparatus is provided that is capable of performing both object detection using image recognition and object detection using movement detection on successively captured images. In the image capturing apparatus, the reliability of the result of the object detection using image recognition is evaluated based on the previous detection results.

  • Patent number: 8208070
    Abstract: When a video output apparatus (100) is connected, a video display apparatus (200) obtains information of content data stored in the video output apparatus (100). Then, based on the obtained information, the video display apparatus (200) determines whether the content data is decodable with respect to itself. If it is not decodable, it requests the video output apparatus (100) to decode the content data before transferring the content data using a data transfer method specified. By doing this, an appropriate transfer protocol is selected automatically when transferring content data between the video display apparatus (200) and the video output apparatus (100).
