    • A bit stream is decoded to generate first quantized DCT-coefficients. The first quantized DCT-coefficients are inversely quantized using a first quantization table, thereby generating DCT-coefficients. The resulting DCT-coefficients are quantized using a second quantization table, thereby generating second quantized DCT-coefficients. Elements in the second quantization table are smaller in value than those in the first quantization table. Predetermined additional information is embedded into the second quantized DCT-coefficients. The second quantized DCT-coefficients having the additional information embedded therein are encoded to produce a bit stream having the additional information embedded therein. The second quantization table is set to be smaller in value than the first quantization table.
    • 解码比特流以产生第一量化DCT系数。 第一量化DCT系数使用第一量化表进行逆量化,从而生成DCT系数。 使用第二量化表量化得到的DCT系数,从而生成第二量化的DCT系数。 第二量化表中的元素的值比第一量化表中的要小。 预定的附加信息被嵌入到第二量化DCT系数中。 具有嵌入其中的附加信息的第二量化DCT系数被编码以产生其中嵌入有附加信息的比特流。 第二量化表被设置为比第一量化表小的值。

    • In a latch apparatus, a latch mechanism arranged at a vehicle body or a door, holds the door towards the vehicle body in a half closed state and a fully closed state. An open lever, a door opening action of which cancels the half closed state or the fully closed state of the door held by the latch mechanism, is arranged to be interlocked with the latch mechanism and to be able to swing. A first handle lever performs an opening action based on an opening operation of a first operation handle. A second handle lever performs an opening action based on an opening operation of a second operation handle. A cancel lever coupled to a closer apparatus that brings the door in the half closed state to the fully closed state, is caused to abut on the open lever to perform a canceling action, thereby disabling a drive of the closer apparatus.
    • 在闩锁装置中,布置在车体或门上的闩锁机构在半闭合状态和完全关闭状态下将车门保持朝向车体。 打开的杠杆,其打开动作抵消由闩锁机构保持的门的半关闭状态或完全关闭状态,被布置成与闩锁机构互锁并且能够摆动。 第一手柄杆基于第一操作手柄的打开操作执行打开动作。 第二手柄杆基于第二操作手柄的打开操作执行打开动作。 使关闭装置的取消杆与将关闭状态的门处于完全关闭状态的关闭装置相接触,使其抵靠在打开的杠杆上以执行取消动作,从而禁止更近的装置的驱动。

    • Even in the case where a positional misalignment occurs to an embedded digital watermark, watermark information is accurately detected. A digital watermark embedding device includes a block dividing section for dividing digital data into a plurality of blocks each having a predetermined size, and a block selecting section for selecting m blocks (m is an integer no less than 2) from the plurality of the blocks in accordance with a predetermined order. The device further includes an additional pattern setting section for setting a combination of m additional patterns which are selected from a plurality types of additional patterns, the combination corresponding to one data element to be embedded into the selected m blocks, and an additional pattern embedding section for embedding each of the set additional patterns into each of the selected blocks.
    • 即使在嵌入式数字水印发生位置偏移的情况下,也能够精确地检测出水印信息。 一种数字水印嵌入装置,具有:数字数据分割部,将数字数据分割成多个具有预定尺寸的块;块选择部,从多个块中选择m个块(m为2以上的整数) 按照预定的顺序。 该装置还包括附加模式设置部分,用于设置从多种类型的附加模式中选择的m个附加模式的组合,对应于要嵌入到所选择的m个模块中的一个数据元素的组合,以及附加模式嵌入部分 用于将每个所设置的附加图案嵌入到每个所选择的块中。
