    摘要： In making a transition from two-point communication to three-point communication, by making preparations for three-point communication without interrupting two-point communication, and by making a transition to three-point communication when preparations are completed, momentary interruption of the conversation is eliminated. That is, while maintaining two-point communication, the transcoders at each point are made to acquire rate control information for all points, after which the transition to three-point communication is made.

    摘要： A first feature value calculator calculates a feature value of an entire screen, and a second feature value calculator calculates a feature value of only an image area designated by designation data stored in a designation data storage. An interpolation determiner outputs a control signal indicative of interpolation-ON if the two feature values are matched or outputs a control signal indicative of interpolation-OFF if not. A center area interpolator uses a motion vector output from a motion estimator to generate an interpolated image within an image area. Side area interpolator performs process of interpolating a side area of the screen on interpolation-ON and stops the process of interpolating a side area of the screen on interpolation-OFF. Therefore, on interpolation-ON, an interpolated frame interpolating the entire screen is output. On interpolation-OFF, an interpolated frame interpolating only the designated image area is output.

    摘要翻译： 第一特征值计算器计算整个屏幕的特征值，第二特征值计算器仅计算由存储在指定数据存储器中的指定数据指定的图像区域的特征值。 如果两个特征值匹配，则内插确定器输出指示内插的控制信号，或者如果不是，则输出指示内插关闭的控制信号。 中心区域内插器使用从运动估计器输出的运动矢量来生成图像区域内的内插图像。 侧面插值器执行插值插入时对画面的侧面进行插值的处理，并且在内插关闭时停止对画面的侧面区域的内插处理。 因此，在内插ON时，输出插入整个画面的内插帧。 在内插关闭时，仅输出指定图像区域的内插帧。

    摘要： In a video signal processing device that generates an interpolated frame between original-image frames formed by an existing video signal, a frame interpolation unit generates pixel interpolation information indicating for each pixel a process in which a pixel forming the interpolated frame is generated. Next, an enhancement-filter-coefficient adjusting unit determines for each pixel a level of enhancement to be applied to the pixel forming the interpolated frame by using pixel interpolation information, and adjusts for each pixel a coefficient of an enhancement filter according to a determined level. An enhancement-filter applying unit then applies the enhancement filter of which coefficient is adjusted for each pixel, to each pixel forming the interpolated frame.

    摘要： In a scan conversion apparatus, a first interpolation pixel generation unit generates an interpolation pixel of a nonexistent line for one of images of two fields based on a motion vector detected between the images of the same parity. A second interpolation pixel generation unit generates an intra-field interpolation pixel of a nonexistent line by using a pixel for the image of the field for which the interpolation pixel has been generated by the first interpolation pixel generation unit, among the images of the two fields. An erroneous-interpolation detection unit detects an erroneous interpolation for the interpolation pixel generated by the first interpolation pixel generation unit by comparing with pixels existing in the upper and lower lines. A signal blending output unit outputs a video signal using interpolation pixels generated by the first and second interpolation pixel generation units based on the detection by the erroneous-interpolation detection unit.

    摘要： A creating apparatus includes a capturing unit, extracting units, and a creating unit. The capturing unit captures a plurality of video signals of images imaged at positions that are different by parallax. The extracting unit extracts a display time-period from at least one of the video signals from among the video signals. The creating unit creates, for a display time-period, a stereoscopic video signal by using the video signals of the images imaged at the positions that are different by parallax. Furthermore, the creating unit creates, for a time other than the display time-period, a stereoscopic video signal having a certain depth by using one of the video signals from among the video signals of the images imaged at the positions that are different by parallax.
