METHOD FOR PROCESSING IMAGE DATA AND SYSTEM FOR IMPLEMENTING SUCH METHOD |
摘要 |
In an image processing system, a method is shown for efficiently transmitting data representing picture information in fields subsequent to a first field and for suppressing motion induced flicker in the processed image. Using previously processed first field data which is used to predict values for picture elements in subsequent fields, a gradient value is calculated which indicates relative picture activity. A difference value for the picture elements in the subsequent fields is calculated and is limited in magnitude by the gradient value for each picture element. The limited difference value is encoded as a function of previous difference value and transmitted to a remote location for decoding and picture reconstruction and display. |
