    摘要: An apparatus, method, and computer-readable medium for motion sensor-based video stabilization. A motion sensor may capture motion data of a video sequence. A controller may compute instantaneous motion of the camera for a current frame of the video sequence and accumulated motion of the camera corresponding to motion of a plurality of frames of the video sequence. The controller may compare the instantaneous motion to a first threshold value, compare the accumulated motion to a second threshold value, and set a video stabilization strength parameter for the current frame based on the results of the comparison. A video stabilization unit may perform video stabilization on the current frame according to the frame's strength parameter.

    摘要: An apparatus, method, and computer-readable medium for motion sensor-based video stabilization. A motion sensor may capture motion data of a video sequence. A controller may compute average motion data of the camera used to capture the video sequence based on motion data from the motion sensor. The controller may then determine the difference between the actual camera motion and the average camera motion to set a video stabilization strength parameter for the frames in the video sequence. A video stabilization unit may utilize the strength parameter to stabilize the frames in the video sequence.

    摘要: This disclosure pertains to devices, methods, and computer readable media for reducing rolling shutter distortion effects in captured video frames based on timestamped positional information obtained from positional sensors in communication with an image capture device. In general, rolling shutter reduction techniques are described for generating and applying image segment-specific perspective transforms to already-captured segments (i.e., portions) of images in a video sequence, so as to counter or compensate for unwanted distortions that occurred during the read out of the image sensor. Such distortions may be due to, for example, the use of CMOS sensors combined with the rapid movement of the image capture device. In contrast to the prior art, rolling shutter reduction techniques described herein may be applied to captured images in real-time or near real-time using positional sensor information and without intensive image processing that would require an analysis of the content of the underlying image data.

    摘要: A spring-sheet-type vibration motor comprises a motor body with an output shaft on a front end and an end cap coupled between a supporting bracket and the motor body on the rear end. The end cap supports one or more electric brushes against the motor body. The supporting bracket includes an end face and a prolonged portion extending therefrom toward the front end of the motor body. One or more connecting terminals are coupled to the supporting bracket, with a first portion coupled to the end face and a front end of a second portion coupled to the prolonged portion. Each terminal further includes a third portion extending obliquely away from the front end of the second portion, a fourth portion bending upward from an end of the third portion, and a contact disposed on a lower surface of a connecting area of the third portion and the fourth portion.

    摘要: A unique sync mark is applied by an encoder to the beginning of each frame in a data packet of a Windows Media™ Audio bitstream by a Microsoft® Windows Media™ Audio (WMA) codec. The WMA decoder handles errors at the frame level for each data packet. When a frame in a data packet of a WMA file is corrupted, the decoder can continue to decode the next frame by searching for the next sync mark at the beginning of the next frame. Accordingly, error propagation is confined to a single frame and the decoder can simultaneously handle bit errors and packet erasures when decompressing a received audio bitstream.

    摘要翻译: 唯一的同步标记由编码器应用于Windows Media TM音频(WMA)编解码器的Windows Media TM音频比特流的数据分组中每帧的开头。 WMA解码器处理每个数据包的帧级别的错误。 当WMA文件的数据分组中的帧被破坏时,解码器可以通过在下一帧开始搜索下一个同步标记来继续解码下一帧。 因此,误差传播局限于单个帧,并且当解压缩所接收的音频比特流时,解码器可以同时处理比特错误和分组擦除。
