摘要： To code the current frame of a moving picture, a weighting coefficient and the mean pixel values in the current frame and a reference frame are obtained. The weighting coefficient is used to modify the mean pixel value in the reference frame, and an offset value is calculated from the resulting modified mean pixel value and the mean pixel value in the current frame. Reference image blocks are then selected from the reference frame, and a predicted image block is generated by applying the weighting coefficient and the offset value to each selected reference image block. Because of the modification of the mean pixel value of the reference frame, pixel values in the predicted image blocks are distributed around the mean pixel value in the current frame, which leads to efficient coding.
摘要翻译：为了对运动图像的当前帧进行编码，获得当前帧和参考帧中的加权系数和平均像素值。加权系数用于修改参考帧中的平均像素值，并根据得到的修改的平均像素值和当前帧中的平均像素值计算偏移值。然后从参考帧中选择参考图像块，并且通过将加权系数和偏移值应用于每个选择的参考图像块来生成预测图像块。由于参考帧的平均像素值的修改，预测图像块中的像素值分布在当前帧中的平均像素值周围，这导致有效的编码。

摘要： A moving image encoding device that encodes a difference between a predicted image and an original image is provided. The predicted image is generated using a weighted reference image, for which a weight is multiplied with and an offset is added to a reference image. The moving image encoding device includes an image data reduction section and a weighting estimation section. The image data reduction section reduces data volumes of the original image and the reference image while retaining characteristics of the original image and the reference image. The weighting estimation section estimates weighting parameters on the basis of image data of the original image and reference image of which the data volumes have been reduced by the image data reduction section.

摘要： A moving picture coding apparatus divides each frame of a moving picture into parts and assigns the parts to different coding units, which compressively code their respective parts. The coding process includes motion compensation with respect to a reference frame. Each coding unit has its own reference frame memory. To generate reference frame data, each coding unit receives, decodes, and decompresses the coded data generated by at least one other coding unit, as well as decompressing the data it has coded itself. Consequently, only ordinary coded data have to be passed between different coding units, which saves bandwidth and eliminates the need for special coding hardware and development and testing tools.

摘要： A camera controller allows the user to control a predominant camera currently shooting a subject and its nearby cameras simply by manipulating the predominant camera. The camera controller is communicably connected to networked cameras held at positions and controls the shooting direction of the imager built in the cameras according to control data. The controller has a video data detector for extracting motion picture data produced by the predominant camera from motion picture data produced by all of the cameras, and a camera control that corrects control data about the shooting camera with camera control request data entered by the user. The camera control outputs the corrected control data about the shooting camera to the predominant camera and also to the nearby cameras near the predominant camera.
