    • An image processing apparatus includes a sort unit for sorting original image data into edge image data and planar image data, a first coding unit for coding the sorted planar image data according to the fractal block coding method, and a second coding unit for coding the sorted edge image data according to a coding method differing from the fractal block coding method. Thus, an image processing apparatus is provided that can have picture quality of a reproduced image improved even for a block that has maximum density difference such as an edge portion. The image processing apparatus can include a first coding unit for coding original image data according to the fractal block coding method, an extractor for extracting error between blocks, a comparator for comparing the amount of extracted error with a predetermined value, and a second coding unit for coding error information according to a coding method different from the fractal block coding method when the error amount is greater than the predetermined value as a result of comparison.
    • 图像处理装置包括:分类单元,用于将原始图像数据分类为边缘图像数据和平面图像数据;第一编码单元,用于根据分形块编码方法对分类的平面图像数据进行编码;以及第二编码单元, 根据与分形块编码方法不同的编码方法的边缘图像数据。 因此,提供了即使对于诸如边缘部分具有最大密度差的块,也能够改善再现图像的图像质量的图像处理装置。 图像处理装置可以包括:第一编码单元,用于根据分形块编码方法对原始图像数据进行编码;提取器,用于提取块之间的误差;比较器,用于将提取的误差量与预定值进行比较;以及第二编码单元 作为比较结果,当误差量大于预定值时,根据与分形块编码方法不同的编码方法编码错误信息。

    • An information processing apparatus communicable with a first terminal device is configured to transmit a message in response to receiving an inquiry. The information processing apparatus includes: reference information referenced when responding to the inquiry received from the first terminal device, which includes at least one set of a question item and a response corresponding to the question item; and history information including inquiries received from the first terminal device and messages that are transmitted or received with respect to the received inquiries. The information processing apparatus opens a first screen displaying information in the history information, receives an operation of selecting change target information from the information displayed on the first screen, opens a second screen for updating the reference information corresponding to the selected change target information, and receives an updating operation for updating the reference information corresponding to the selected change target information through the second screen.
