    • When data of one block is subjected to Huffman decoding (S100 to S120), inverse quantization processing is executed on the decoded data (S130), and when a present block is a starting point block, starting point restoring information (file pointer, decoding intermediate information and DC component) for restoring the image file with the block as a starting point is stored in a predetermined area of a data buffer (S140, S150). Then, inverse DCT calculation processing is carried out, color conversion processing is executed (S160, S170) and the histogram of RGB values is accumulated and stored in a predetermined area of the data buffer (S180).
    • 当对一个块的数据进行霍夫曼解码(S100至S120)时,对解码数据执行逆量化处理(S130),当当前块是起始点时,起始点恢复信息(文件指针,解码中间件 信息和DC分量)存储在数据缓冲器的预定区域中(S140,S150)。 然后,执行逆DCT计算处理,进行颜色转换处理(S160,S170),并且RGB值的直方图被累积并存储在数据缓冲器的预定区域中(S180)。

    • An image scanner printer that reads an original image and that prints out the original image includes a red-eye detection unit, a YCC image storage processing unit, a YCC/RGB conversion unit, a red-eye correction unit, and a print data creating unit. The red-eye detection unit detects red-eye that is included in an image corresponding to a predetermined number of lines of RGB image data when the original image is read. The YCC image storage processing unit converts the predetermined number of lines of the RGB image data into YCC image data and stores all the data as one unit JPEG image. The YCC/RGB conversion unit converts the YCC image data into RGB image data in units of a line or in units of a predetermined number of lines. The red-eye correction unit executes red-eye correction on the RGB image data when an image corresponding to the converted RGB image data includes a red-eye area that is stored in a red-eye table. When print data are created from the RGB image data, the print data creating unit, for RGB image data, among the RGB image data, on which the red-eye correction has been performed, creates print data from the RGB image data on which the red-eye correction has been performed.
    • 读取原始图像并打印原始图像的图像扫描仪打印机包括红眼检测单元,YCC图像存储处理单元,YCC / RGB转换单元,红眼校正单元和创建的打印数据 单元。 当读取原始图像时,红眼检测单元检测包括在与预定数量的RGB图像数据相对应的图像中的红眼。 YCC图像存储处理单元将预定数量的RGB图像数据的行转换为YCC图像数据,并将所有数据存储为一个单位JPEG图像。 YCC / RGB转换单元将YCC图像数据以行或以预定行数为单位转换为RGB图像数据。 当与转换的RGB图像数据相对应的图像包括存储在红眼表中的红眼区域时,红眼校正单元对RGB图像数据执行红眼校正。 当从RGB图像数据创建打印数据时,用于RGB图像数据的打印数据创建单元在其上执行了红眼校正的RGB图像数据中,从根据RGB图像数据的RGB图像数据创建打印数据, 已进行红眼修正。

    • In order to process image data including a plurality of pixels, a plurality of pixel groups, each of which includes a plurality of pixels, are extracted from the image data sequentially. Next, it is judged whether each of the pixel groups includes only at least one of a white pixel and a black pixel. At least one first pixel group in the pixel groups is binarized in accordance with an arrangement of the at least one of the white pixel and the black pixel therein, in a case where it is judged that the first pixel group includes only at least one of the white pixel and the black pixel, thereby generating at least one first data item. A first resolution of at least one second pixel group in the pixel groups is reduced to a second resolution, in a case where it is judged that the second pixel group includes at least one pixel other than the white pixel and the black pixel, thereby generating at least one second data item.
