    • An image processing apparatus performs color conversion processing on an input image. The image processing apparatus includes a block pallet conversion unit, a first color converting unit and a restoration unit. The block pallet conversion unit converts the input image in units of blocks into (i) pallet color information including pallet colors number of which is less than pixels included in one of the blocks and (ii) selection information used to select one of the pallet colors for each pixel. The first color converting unit performs color conversion on the pallet color information obtained by the block pallet conversion unit. The restoration unit selects for each pixel, based on the selection information, one of the pallet colors of the pallet color information, which is color-converted by the first color converting unit, to restores an image.
    • 图像处理装置对输入图像执行颜色转换处理。 图像处理装置包括块托盘转换单元,第一颜色转换单元和恢复单元。 块托盘转换单元将输入图像以块为单位转换成(i)托盘颜色信息,其中托盘颜色信息小于包括在一个块中的像素的托盘颜色数量,以及(ii)用于选择托盘颜色之一的选择信息 对于每个像素 第一颜色转换单元对由块托盘转换单元获得的托盘颜色信息执行颜色转换。 恢复单元根据选择信息为每个像素选择由第一颜色转换单元进行颜色转换的托盘颜色信息的托盘颜色之一,以恢复图像。

    • There is provided a centrifugal fan including an upper casing which has an air suction opening, a lower casing, and an impeller which is disposed between the upper casing and the lower casing. The impeller includes an upper shroud which is provided on an upper casing side, and a plurality of blades which are arranged along a circumference direction below the upper shroud, and is rotatable around a rotary shaft. The upper casing and the lower casing configure an open-type casing. A surface of the upper shroud facing the upper casing includes a first portion which becomes closer to the lower casing as separating further from the rotary shaft. A surface of the upper casing facing the upper shroud includes a second portion which faces the first portion of the upper shroud and becomes closer to the lower casing as separating further from the rotary shaft.
    • 提供了一种离心式风扇,其包括具有空气吸入口,下壳体和设置在上壳体和下壳体之间的叶轮的上壳体。 叶轮包括设置在上壳体侧的上护罩和沿着上护罩下方的圆周方向布置的多个叶片,并且可绕旋转轴旋转。 上壳体和下壳体构成开式壳体。 上罩的面向上壳体的表面包括第一部分,该第一部分随着与旋转轴分离而变得更靠近下壳体。 面向上护罩的上壳体的表面包括与上护罩的第一部分相对的第二部分,并且随着离开旋转轴的分离而变得更接近下壳体。
