    • An image processing device includes a scanner, which reads a plurality of images and inputs them as multivalue digital image data; a matching data producing section which, based on the inputted multivalue image data, produces matching data for joining the respective inputted images; a post-processing section, which binarizes the image data of each image inputted by the scanner; a joining section, which synthesizes the respective inputted images into a single image by joining the binary data produced by the post-processing section, which corresponds to the image data of the respective inputted images, on the basis of the matching data produced by the matching data producing section; and a printer for outputting the image joined by the joining section. Thus an image processing device can be provided which is capable of joining any type of image, whether from written characters, halftone dot, or photographic originals, and of performing this joining processing at high speed.
    • 图像处理装置包括扫描器,其读取多个图像并将其输入为多值数字图像数据; 匹配数据产生部分,基于输入的多值图像数据,产生用于连接各个输入图像的匹配数据; 后处理部分,其对由扫描器输入的每个图像的图像数据进行二值化; 一个接合部分,其通过将由后处理部分产生的二进制数据与对应于各个输入图像的图像数据相对应的二进制数据通过匹配产生的匹配数据合成到单个图像中 数据生成部分; 以及用于输出由所述连接部连接的图像的打印机。 因此,可以提供能够连接任何类型的图像的图像处理装置,无论是从书写字符,半色调点或照相原稿,以及高速执行该接合处理。

    • A moving image encoding apparatus includes a first-step encoding section for executing a plurality of times first-step encoding by use of different quantization control variables; a code-amount estimation section for estimating, for all the quantization control variables, an amount of codes generated for each frame by making use of a plurality of results of the encoding; a code-amount allocation section for allocating an amount of codes for each frame on the basis of results of the estimation; and a second-step encoding section for executing second-step encoding on the basis of the amount of codes allocated to each frame. The first-step encoding section changes the number of times of execution of the encoding in accordance with the attribute of each frame, and omits a portion of processes contained in the coding process in the second and subsequent executions of the encoding process.
    • 运动图像编码装置包括:第一步编码部分,用于通过使用不同的量化控制变量执行多次第一步编码; 码量估计部分,用于通过利用所述编码的多个结果,针对所有的量化控制变量来估计针对每一帧产生的代码量; 码量分配部分,用于根据估计结果分配每帧的码量; 以及第二步编码部分,用于基于分配给每个帧的代码量来执行第二步编码。 第一步编码单元根据每帧的属性改变编码的执行次数,并且在编码处理的第二次和随后的执行中省略包含在编码处理中的处理的一部分。
