    摘要: 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.

    摘要: 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.
