    • PROBLEM TO BE SOLVED: To improve the experience of a multimedia multipoint user by correlating the position of a conference attendance on a display to the voice of the conference attendance.SOLUTION: Audio streams are differentiated so as to emphasize broadcasting of the audio streams through one or more loudspeakers closest to a position of a speaking endpoint in a videoconference layout that is displayed at the endpoint. For example, the audio broadcasted at a loudspeaker that is at a far-side of the screen might be attenuated or delayed compared to audio broadcasted at a loudspeaker that is located at a near-side of the display. Audio signals from two or more endpoints according to the positions in a layout of the endpoints are processed and then the endpoints broadcast spatial audio streams.
    • 要解决的问题:通过将显示器上的会议考勤的位置与会议出席的语音相关联来改善多媒体多点用户的体验。 解决方案:音频流被区分,以便通过一个或多个扬声器来强调音频流的广播,该扬声器最靠近在端点处显示的视频会议布局中的说话端点的位置。 例如,与在位于显示器附近的扬声器处广播的音频相比,在屏幕的远侧的扬声器处广播的音频可能衰减或延迟。 来自两个或更多个端点的根据端点布局中的位置的音频信号被处理,然后端点广播空间音频流。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a drawn image sharing device capable of optimally setting an imaging device more quickly than a conventional one.SOLUTION: A drawn image sharing device includes: an image division section 26 for dividing an image acquired from an imaging device by an image acquisition section 22 into first and second images; and an image combination section 27 for combining a difference image generated by a difference image generation section 23. The difference image generation section 23 generates a first difference image representing a difference between an image having the same zone as the first image and the first image in an image supplied from an image supply section 21, and generates a second difference image representing a difference between an image having the same zone as the second image and the second image in an image supplied from the image supply section 21. The image combination section 27 arranges the first difference image at a position of the second image and arranges the second difference image at a position of the first image, thereby combining the first difference image with the second difference image. The image supply section 21 supplies the image combined by the image combination section 27 to an imaging device so as to form an image on a drawing object.
    • 要解决的问题:提供能够比传统图像更快地设置成像装置的绘制图像共享装置。 绘制图像共享装置包括:图像分割部分26,用于将由图像获取部分22获取的图像获取的图像划分成第一和第二图像; 以及用于组合由差分图像生成部23生成的差异图像的图像组合部27.差异图像生成部23生成表示与第一图像具有相同区域的图像与第一图像之间的差异的第一差异图像 从图像供给部21提供的图像,并且生成表示从图像供给部21提供的图像中表示与第二图像具有相同区域的图像与第二图像之间的差异的第二差分图像。图像组合部分27 将第一差分图像排列在第二图像的位置,并将第二差分图像排列在第一图像的位置处,从而将第一差分图像与第二差分图像组合。 图像供给部21将由图像合成部27组合的图像提供给成像装置,以便在绘图对象上形成图像。 版权所有(C)2012,JPO&INPIT
