    • An image data processing apparatus includes the following elements. A lossless compression device performs lossless compression. A configuration controller performs control so that a first configuration including a first line memory set and a decompression circuit set and a second configuration including a second line memory set are selectively set in a reconfigurable circuit. A maximum size determining device determines the maximum size of lines of the compressed image data. An output controller performs control so that, when the maximum size is equal to or smaller than a predetermined threshold, the first configuration is set and the compressed image data is output to an image processing circuit via the first line memory set, and so that, when the maximum size is greater than the predetermined threshold, the second configuration is set and the non-compressed image data is output to the image processing circuit via the second line memory set.
    • 图像数据处理装置包括以下要素。 无损压缩装置执行无损压缩。 配置控制器执行控制,使得在可重新配置的电路中选择性地设置包括第一行存储器组和解压缩电路组的第一配置以及包括第二行存储器组的第二配置。 最大尺寸确定装置确定压缩图像数据的行的最大尺寸。 输出控制器执行控制,使得当最大尺寸等于或小于预定阈值时,设置第一配置,并且经由第一行存储器将经压缩的图像数据输出到图像处理电路, 当最大尺寸大于预定阈值时,设置第二配置,并且经由第二行存储器组将非压缩图像数据输出到图像处理电路。
