    摘要: A method for motion accounting and compensation while encoding allows improvement of the restored image quality. Image is a predicted frame in video sequence. Motion compensation is understood as an error residual signal compressing scheme, executed during video sequence encoding. According to the teachings of the current invention, errors are accounted for during encoding. Error accounting is subtracting the original image from the predicted frame. The error values are written to the output stream compactly with the minimum code length. The stored error values are added to the predicted frame during the decoding process. The method taught herein is applied for all the predicted frames from the video sequence, thereby allowing one to improve the quality of decompressed video film that was compressed with a significant compression ratio.

    摘要: A method of manufacturing an electronic component with a contact having a terminal section for brazing and a contact section includes steps that construct a contact base member of a material that is poorly wettable, forms a primer plating layer of a material that is poorly wettable to the weld brazing material on the base member, forms a finish plating layer of a material that is highly wettable to the weld brazing material on the primer plating layer, and selectively removes a portion of the finish plating layer to obtain an exposed region of the primer plating layer that serves as an arresting region for arresting the weld brazing material from creeping up and migrating along the highly wettable finish plating layer in brazing the terminal section to the brazing pad of a wiring board.
