    • A plurality of texture data of a surface of an object to be displayed as viewed from a plurality of assumed directions are stored in a texture memory. When a CPU sends to a graphic processor information specifying a shape of the surface, a direction to view the surface and a texture in the texture memory as a command, a geometric operation unit produces read information of the texture memory based on the input information. A triangle generator reads the texture data corresponding to the view direction of the surface of the object by the read information for texture mapping. An image of the texture mapped image of the surface of the object is stored in a frame memory and displayed on a monitor. When there is no texture data corresponding to the view direction, a plurality of texture data closest thereto are read from the texture memory and interpolated to produce an appropriate texture data.
    • 从多个假定方向观看要显示的对象的表面的多个纹理数据被存储在纹理存储器中。 当CPU向图形处理器发送指定表面形状的信息时,将纹理存储器中的表面和纹理的方向作为命令,几何运算单元根据输入信息产生纹理存储器的读取信息。 三角形生成器通过用于纹理映射的读取信息来读取对应于物体表面的视图方向的纹理数据。 将物体表面的纹理映射图像的图像存储在帧存储器中并显示在监视器上。 当没有对应于视图方向的纹理数据时,从纹理存储器读取与其最接近的多个纹理数据,并进行内插以产生适当的纹理数据。

    • A technology for detecting an RFID by a reader writer and transmitting harmonics for reading and writing the RFID timely without using an object detection sensor is provided. Using a nonlinearity of a rectifier or a demodulator in an IC chip of the RFID, a continuous wave or a modulated wave of two or more different frequencies is output from the reader writer. The RFID receives the continuous wave or the modulated wave of two or more different frequencies and the reader writer receives harmonics intermodulation generated by the rectifier or the demodulator in the IC chip. Therefore, the RFID can be detected without any special object detection sensor, and a modulated wave for reading or writing the RFID can be transmitted.

    • In order to provide a highly secure system at a low cost without providing a complicated logic circuit for an RFID tag, in a system including an RFID tag (10) and a interrogator (20), the interrogator (10) is provided with a password creating unit (1100) which computes an electronic key (131) and a keyword unique to the RFID tag with a predetermined irreversible function to create a password. By using the password as a key, item information of an item attached with the RFID tag (20) is encrypted with a predetermined encryption function. The encrypted item information and the keyword are written to the RFID tag (20). The interrogator (10) reads the encrypted item information and the keyword from the RFID tag (20), causes the password creating unit (1100) to compute the password by using the keyword, and uses the password as a key to decrypt the read encrypted item information.

    • A graphics system which accelerates generation of pixels including transparent objects by simply adding more rendering devices. The system has composition means and a plurality of rendering devices each comprising a geometric processor, a rendering processor and a frame memory that holds color, depth and weight data in a screen bit map format. Given a plurality of sets of color, depth and weight data about any one pixel position from the frame memories, the composition means first compares the depth data, and multiplies successively the weight and color data starting with those corresponding to the depth data closest to the foreground, thereby generating new pixel data. The system thus permits merging of transparent objects.
