摘要： The present system ensures that external noise sources do not taint sensor data recorded about a user's sleep parameters, to reduces false positives and false negatives, and provide a more accurate record of the user's sleep sounds, by cycling on and off noise sources. Additionally, the present system, in one embodiment, may be used to track changes in sound patterns from the user and from the environment. This may lead to early warning of health issues, as well as issues with the devices in the bedroom.

摘要： A video processing circuit includes a processor that receives an encoded image having first and second regions, decodes the first region of the image, modifies the decoded first region, and re-encodes the modified first region. Such a circuit allows one to modify a region of an image by decoding and re-encoding only that region instead of the entire image. For example, if one wishes to overlay an EPG on a bottom portion of a video frame, then the circuit can decode only the EPG and the bottom portion of the frame, overlay the decoded EPG on the bottom frame portion, and re-encode the overlaid bottom frame portion. Therefore, this technique often reduces the processing time, and thus the cost and complexity of the processing circuit, as compared to a circuit that decodes and re-encode the entire frame during an image overlay process.
摘要翻译：视频处理电路包括接收具有第一和第二区域的编码图像的处理器，对图像的第一区域进行解码，修改解码的第一区域，并重新编码修改的第一区域。这样的电路允许通过仅解码和重新编码该区域而不是整个图像来修改图像的区域。例如，如果希望将EPG覆盖在视频帧的底部上，则该电路只能解码该EPG和该帧的底部部分，将解码的EPG覆盖在底部帧部分上，并重新编码重叠的底部框架部分。因此，与在图像重叠处理期间对整个帧进行解码和重新编码的电路相比，该技术通常减少了处理时间，从而降低了处理电路的成本和复杂性。

摘要： An improved method for automatic exposure control at a digital camera is described. In response to a user request for capture of a digital image, image data is captured on the camera's image sensor. The captured image data includes pixel values of brightness of pixels of the image sensor. A histogram of pixel values is generated based upon brightness of pixels of the image sensor. The histogram that is generated is then evaluated to determine whether an image is overexposed or underexposed. Coarse exposure settings for capture of a digital image are automatically generated based upon scaling the histogram of pixel values towards the midpoint of a pre-selected interval. The coarse exposure settings and image data that have been captured are evaluated to determine whether light sources are present. In the event that light sources are determined not to be present, the coarse exposure settings are adjusted based upon not scaling said histogram beyond the largest histogram value.
摘要翻译：描述了用于数字照相机的自动曝光控制的改进方法。响应于用户捕获数字图像的请求，在相机的图像传感器上捕获图像数据。拍摄图像数据包括图像传感器的像素的亮度的像素值。基于图像传感器的像素的亮度生成像素值的直方图。然后评估生成的直方图以确定图像是否曝光过度还是曝光不足。基于将像素值的直方图朝向预选间隔的中点缩放来自动生成用于捕获数字图像的粗暴曝光设置。评估已经捕获的粗暴曝光设置和图像数据以确定是否存在光源。在确定不存在光源的情况下，基于不缩放所述直方图超过最大直方图值来调整粗略曝光设置。

摘要： A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”
摘要翻译：描述了一种媒体假脱机系统，其提供用于从客户端设备有效地传输媒体内容的方法，例如来自无线数字照相机的数字图像的传输。媒体假脱机程序或网关通过充当瘦客户机设备与目标主机或服务器（由服务器基础设施支持）之间的协议网关来解决无线传输问题。更具体地说，本发明的媒体假脱机器作为瘦客户端设备（例如，无线数字照相机形式的“移动可视通信器”）和服务器基础设施（例如基于服务器的计算机系统或“ 摄影服务提供商的Web服务器“）。该任务需要接受来自各种客户端设备（例如，无线数字照相机）的多个同时连接，从那些设备提取信息（例如，数字照片或其他媒体内容），然后将该信息上传到目标服务器基础设施。在基本操作中，媒体后台处理程序向每个客户端设备查询客户端设备认为应上传的信息（例如，媒体，如图片），然后介质后台处理程序查询服务器基础结构以获得尚未上传的图片子集。这种改进的设备和目标主机之间的信息的协调或同步允许通过基本上允许媒体假脱机程序“拾取其停留在何处”来有效地恢复丢弃的蜂窝数据呼叫。

摘要： A system providing methods for improved compression of images that have been compressed using Discrete Cosine Transform (DCT) based compression is described. A digital image that has been compressed using DCT based compression, such as an image compressed using the Joint Photographic Experts Group (JPEG) compression scheme, is received and partially decompressed to generate DCT coefficients of the image. The decoded coefficients of the image are then rearranged to aggregate like frequencies together. After rearrangement, the image is recompressed using a wavelet-based compression scheme.
