    • An information processing apparatus searches search target frame images in video data to find a frame image matching a search query frame image. An extractor extracts characteristic quantities expressing the characteristics of respective images. A reliability judge judges the reliability of the values of each characteristic quantity in a characteristic quantity group extracted from the search query frame. If certain characteristic quantity values in the search query frame are judged to be of low reliability, the converter converts those values into predetermined values. Values are similarly converted for all search target frames. A comparer compares the converted characteristic quantities in the search query frame to the converted characteristic quantities in all search target frames. On the basis of the comparisons, a decision unit then chooses a search solution frame that matches the search query frame. In so doing, search processing robustness with respect to data variance is improved.
    • 信息处理设备搜索视频数据中的搜索目标帧图像以找到与搜索查询帧图像匹配的帧图像。 提取器提取表示各图像的特征的特征量。 可靠性判断判断从搜索查询框中提取的特征量组中的每个特征量的值的可靠性。 如果判断搜索查询帧中的某些特征量值具有低可靠性,则转换器将这些值转换成预定值。 对所有搜索目标帧类似地转换值。 比较器将搜索查询帧中的转换特征量与所有搜索目标帧中的转换特征量进行比较。 在比较的基础上,决策单元然后选择与搜索查询框架匹配的搜索解决方案框架。 这样做,提高了关于数据方差的搜索处理鲁棒性。

    • The present invention relates to a signal processing device and signal processing method, and program and recording medium, whereby images and the like closer approximating real world signals can be obtained. With regard to an input image of dimensions fewer than the dimensions of actual world light signals, wherein actual world light signals have been projected and a part of the continuity of the actual world light signals has been lost, actual world signals are estimated at an actual world signal estimating unit 10003 from the input image within a processing region set at a processing region setting unit 10001, corresponding to continuity set at a continuity setting unit 10002. On the other hand, information relating to at least one of processing region, continuity, and actual world signals, is supplied from a user I/F 10006 to the processing region setting unit 10001, continuity setting unit 10002, or actual world signal estimating unit 10003, according to user operations. The present invention can be applied to, for example, cases of removing movement blurring from an image, for example.
    • 本发明涉及一种信号处理装置和信号处理方法以及程序和记录介质,由此可以获得近似真实世界信号的图像等。 对于尺寸小于实际世界光信号的尺寸的输入图像,其中实际世界光信号已被投影并且实际世界光信号的一部分连续性已经丢失,实际的世界信号被估计为实际的世界信号 对应于在连续性设定部10002设定的连续性,处理区域设定部10001设定的处理区域内的输入图像的世界信号推定部10003。 另一方面,从用户I / F 10006向处理区域设定部10001,连续性设定部10002或实际世界信号推定部提供与处理区域,连续性,实际世界信号中的至少一个有关的信息 10003,根据用户操作。 例如,本发明可以应用于例如从图像中去除运动模糊的情况。
