    • The image display apparatus of the present invention examines the transparency of a pixel to determine whether the Z coordinate of the pixel should be written in the depth buffer. Therefore, when the objects which are constituted by polygons, wherein opaque pixels and translucent pixels coexist, intersect each other, the variation in the display of image patterns which are to be displayed is increased. Since the writing control is performed under simple conditions, i.e., in accordance with the transparency of a pixel, an image closer to the ideal one can be selected without substantially increasing the load imposed on the rendering circuit.
    • 本发明的图像显示装置检查像素的透明度,以确定像素的Z坐标是否应写入深度缓冲器。 因此,当由不透明像素和半透明像素共存的由多边形构成的物体相互交叉时,增加了要显示的图像图案的显示的变化。 由于在简单的条件下执行写入控制,即根据像素的透明度,可以选择更接近理想图像的图像,而基本上不增加施加在渲染电路上的负载。

    • Provided is a digitizer function-equipped liquid crystal display device capable of preventing the wire shadows of a loop antenna from being projected on a liquid crystal panel and capable of being applied to a large size liquid crystal panel. It is also possible to provide an information processing electronic device and a game device provided with the digitizer function-equipped liquid crystal display device. Here, the digitizer function-equipped liquid crystal display device includes: a liquid crystal panel 1; a light diffusion member 2 which is disposed between the liquid crystal panel 1 and a backlight 5 irradiating the liquid crystal panel 1 with light; an electromagnetic induction type loop antenna which is disposed at a portion apart from the light diffusion member 2 in the direction toward the backlight 5 by a predetermined spacing so as to detect a position on the plane of the liquid crystal panel 1 in one coordinate axis direction and another coordinate axis direction that intersects the one coordinate axis direction; and a spacing retaining means for retaining the spacing between the light diffusion member 2 and loop antenna at a predetermined spacing value. As the spacing retaining means, a first light transmitting member 3 formed of a plate material having a light transmitting property is used.

    • In the present invention, the appearance frequency of all image information items to be encoded is determined, short code words are allocated from predetermined code words in accordance with leaves of a bifurcating scheme to image information items having an appearance frequency up to a predetermined ranking, in sequential fashion starting from the image information item having the highest appearance frequency, and a predetermined identifier is appended to the beginning of each of the remaining image information items, the resulting codes being taken as the respective code words allocated to said remaining image information items. Thereby, it is possible to provide an image information encoding method whereby decoding by hardware can be performed readily.
    • 在本发明中,确定要编码的所有图像信息项目的出现频率,根据分叉方案的叶片从预定码字分配短码字到具有高达预定等级的出现频率的图像信息项, 从具有最高出现频率的图像信息项开始的顺序方式,并且在每个剩余图像信息项的开头附加预定标识符,将所得到的代码作为分配给所述剩余图像信息项的各个代码字 。 因此,可以提供一种图像信息编码方法,从而可以容易地执行硬件解码。
