    • A temporarily labelled image data generating circuit is composed of an initial label memory, which stores the initial temporary label values of pixels that are connected within the line being scanned, and a run length counter, which counts the number of pixels of the connected pixels, and finally labelled image data is generated following the generation of temporarily labelled image data and temporary label table data, which indicate the conversion relation for the modification of the temporary labels, using the initial label memory and run length counter, which improves the processing speed by reducing the number of times the memory is accessed and reduces the storage capacity of the working memory.
    • 临时标记的图像数据生成电路由初始标签存储器构成,该初始标签存储器存储连接在被扫描的行中的像素的初始临时标签值,以及对所连接的像素的像素数进行计数的游程长度计数器, 并且使用初始标签存储器和游程长度计数器生成临时标记的图像数据和临时标签表数据之后生成标记的图像数据,这些临时标签表数据指示用于修改临时标签的转换关系,这提高了处理速度 减少内存访问次数,减少工作内存的存储容量。
