    • With a minimal process load, to determine level of the image of an image data file, for image data files of a format that saves images in the form of coefficients of discrete frequency components. Image data that includes a plurality of coefficients representing the pattern of change of color of the image are acquired (Step S10). Multiple sets of basic pattern data that respectively include a plurality of basic coefficients representing basic patterns of color change are prepared. Then, based on a comparison of the two, one set of selected basic pattern data is selected from among the multiple sets of basic pattern data (Step S20). Subsequently, the blur level of the image of the image data is calculated, based on the basic blur level associated with the selected basic pattern data (S30-S70).
    • 以最小的过程负载,确定图像数据文件的图像的级别,用于以以离散频率分量的系数的形式保存图像的格式的图像数据文件。 获取包含表示图像的颜色变化图案的多个系数的图像数据(步骤S10)。 准备分别包括表示颜色变化的基本图案的多个基本系数的多组基本图案数据。 然后,基于两者的比较,从多组基本模式数据中选择一组选择的基本模式数据(步骤S20)。 随后,基于与所选择的基本图案数据相关联的基本模糊级别来计算图像数据的图像的模糊级别(S30-S70)。

    • In response to a search request, the type of the terminal from which the request originated is determined, and a selection history is weighted and accumulated so that the order of the results of a search carried out according to set search conditions varies depending on the selection history. In the case where the type of the request origin terminal is a terminal type in which the number of search results that can be displayed on a single screen is less than in other terminal types or the movement of the screen is more complicated than in other terminal types and search results have been selected across a plurality of screens, a greater weight is applied to the selection history of the selected search results than for other terminal types.
    • 响应于搜索请求,确定发起请求的终端的类型,并且对选择历史进行加权和累加,使得根据设置的搜索条件执行的搜索结果的顺序根据选择而变化 历史。 在请求起始终端的类型是可以在单个屏幕上显示的搜索结果的数量小于其他终端类型的终端类型或者屏幕的移动比其他终端中的复杂的终端类型的情况下 已经在多个屏幕中选择了类型和搜索结果,对于所选择的搜索结果的选择历史,对于其他终端类型应用更大的权重。

    • A printer fetches a horizontal direction DCT coefficient group and a vertical direction DCT coefficient group for each block from the JPEG data. The printer selects edge patterns similar to the brightness changes expressed by these coefficient groups from a specified table, and records those pattern numbers in a RAM. The printer judges whether or not the brightness changes of the blocks with each other adjacent are continuous based on the pattern number of each block recorded in the RAM. And by connecting the edge patterns when those brightness changes are continuous, the printer accumulates the blur widths that exist extending over the blocks. Then, based on this cumulative value, the printer determines the presence or absence of image blur. It is possible thereby to detect with good precision the blur of images even for high resolution images while reducing the used memory capacity.
    • 打印机从JPEG数据中取出每个块的水平方向DCT系数组和垂直方向DCT系数组。 打印机从指定的表中选择与这些系数组所表示的亮度变化类似的边缘图案,并将这些图案号记录在RAM中。 打印机基于记录在RAM中的每个块的图案号来判断彼此相邻的块的亮度变化是否连续。 并且通过连接边缘图案,当这些亮度变化是连续的时,打印机会累积存在于块上的模糊宽度。 然后,基于该累计值,打印机确定图像模糊的存在或不存在。 因此,即使对于高分辨率图像也可以精确地检测图像的模糊,同时减少了所使用的存储器容量。
