    • An image information transmission apparatus of this invention encodes and transmits image information. An image information signal of one frame consisting of a plurality of pixel data is divided into a plurality of blocks each consisting of a predetermined number of pixel data. At least two reference value data associated with a dynamic range of levels of the pixel data constituting each of the divided blocks, and distribution state data associated with a distribution state thereof are formed. Each pixel data constituting the block is encoded on the basis of the formed reference value data and the formed distribution state data to obtain encoded data. A transmission data series is formed and transmitted using the formed reference value data, the formed distribution state data, and the encoded data as transmission units. Therefore, the image information signal can be highly effectively transmitted with minimum image quality degradation caused by encoding.
    • 本发明的图像信息发送装置对图像信息进行编码和发送。 由多个像素数据构成的一帧的图像信息信号被分成多个块,每个块由预定数量的像素数据组成。 形成与构成每个分割块的像素数据的动态动态范围相关联的至少两个参考值数据,以及与其分布状态相关联的分配状态数据。 基于所形成的基准值数据和形成的分布状态数据对构成块的每个像素数据进行编码以获得编码数据。 使用形成的基准值数据,形成的分配状态数据和编码数据作为发送单位来形成和发送发送数据序列。 因此,可以以由编码导致的最小图像质量劣化来高效地传输图像信息信号。
