    • A simple compression and decompression method provides excellent effects by reducing the storage capacity of an image memory, while adapting to the properties of image. On the basis of luminance information extracted by a luminance extraction block 110, a compression conversion rule setting block 120 sets a compression conversion rule to a compression conversion table 130. In accordance with this compression conversion rule, an image compression block 140 compresses original image data and holds the compressed image data in an image memory 150 along with a type of the compression conversion rule. This type of the compression conversion rule held in the image memory 150 is extracted by a decompression conversion rule setting block 160. In accordance with this type, a decompression conversion rule is set to a decompression conversion table 170. In accordance with the decompression conversion rule set to the decompression conversion table 170, an image decompression block 180 decompresses the compressed image data held in the image memory 150.
    • 简单的压缩和解压缩方法通过降低图像存储器的存储容量,同时适应图像的属性,提供了出色的效果。 根据由亮度提取块110提取的亮度信息,压缩转换规则设置块120将压缩转换规则设置为压缩转换表130.根据该压缩转换规则,图像压缩块140压缩原始图像数据 并且将压缩图像数据与压缩转换规则的类型一起保存在图像存储器150中。 通过解压缩转换规则设置块160提取保存在图像存储器150中的这种类型的压缩转换规则。根据这种类型,解压缩转换规则被设置为解压缩转换表170.根据解压缩转换规则 设置到解压缩转换表170,图像解压缩块180解压缩保存在图像存储器150中的压缩图像数据。
