Standard converter for TV equipment - avoids motion fuzziness with rapid movements by combining output half images to give harmonic movements

摘要

The standard converter, which is used for processing television pictures, has electronic storage tubes and uses a fresly cleared store for each of the output half-images or half-frames in the output standard. The input standard has its half-images broken down into weighted components for passing into the store at the appropriate position in the cycle. There are 2 or 3 half images from the input standard are used to construct one output standard half-image. The advantage lies in combining the output half-images so that movements are harmonic, which avoids fuzziness and jerky effects with rapid movement.
