Abstract: Various examples related to determining a location of an active speaker are provided. In one example, image data of a room from an image capture device is received and a three dimensional model is generated. First audio data from a first microphone array at the image capture device is received. Second audio data from a second microphone array laterally spaced from the image capture device is received. Using the three dimensional model, a location of the second microphone array with respect to the image capture device is determined. Using the audio data and the location and angular orientation of the second microphone array, an estimated location of the active speaker is determined. Using the estimated location, a setting for the image capture device is determined and outputted to highlight the active speaker.

Abstract: A privacy camera, such as a light field camera that includes an array of cameras or an RGBZ camera(s)) is used to capture images and display images according to a selected privacy mode. The privacy mode may include a blur background mode and a background replacement mode and can be automatically selected based on the meeting type, participants, location, and device type. A region of interest and/or an object(s) of interest (e.g. one or more persons in a foreground) is determined and the privacy camera is configured to clearly show the region/object of interest and obscure or replace the background according to the selected privacy mode. The displayed image includes the region/object(s) of interest clearly shown (e.g. in focus) and any objects in a background of the combined image shown having a limited depth of field (e.g. blurry/not in focus) and/or the background replaced with another image and/or fill.

Abstract translation: 使用隐私摄像机，例如包括摄像机阵列或RGBZ摄像机的光场摄像机），以根据所选隐私模式捕获图像和显示图像。 隐私模式可以包括模糊背景模式和背景替换模式，并且可以基于会议类型，参与者，位置和设备类型自动选择。 确定感兴趣的区域和/或感兴趣的对象（例如前景中的一个或多个人），并且隐私摄像机被配置为清楚地显示感兴趣的区域/对象，并且根据 所选隐私模式。 显示的图像包括清楚地显示（例如，焦点）的感兴趣的区域/对象，并且所示的组合图像的背景中的任何物体具有有限的景深（例如模糊/不在焦点）和/或背景 替换为另一个图像和/或填充。
