    • An image signal encoding apparatus for encoding an image signal in which image of one picture plane consisting of a plurality of pixel data are divided into a plurality of blocks each consisting of a predetermined number of pixel data. For each of the blocks, a pair of reference value data regarding the maximum and minimum values of the levels of the pixel data constructing the block are formed. On the basis of the formed reference value data, encoded date is formed by encoding each of the pixel data of the block. Decoded data is formed by decoding the encoded data formed on the basis of the reference value data. By comparing each of the pixel data of the block with the decoded data, errors are detected. The reference value data are corrected in accordance with the result of the detection. Thus, the encoding errors are reduced and it is possible to perform the encoding with less deterioration in picture quality of the image signal.
    • 一种用于编码图像信号的图像信号编码装置,其中由多个像素数据组成的一个图像的图像被划分成由预定数量的像素数据组成的多个块。 对于每个块,形成关于构成该块的像素数据的电平的最大值和最小值的一对参考值数据。 基于形成的参考值数据,通过对块的每个像素数据进行编码来形成编码日期。 通过对基于参考值数据形成的编码数据进行解码来形成解码数据。 通过将块的像素数据与解码数据进行比较,检测出错误。 参考值数据根据检测结果进行校正。 因此,编码错误减少,并且可以以较少的图像信号的图像质量劣化来执行编码。
