Method and apparatus of image processing

摘要: An image processing apparatus generates an after-image effect by using a first memory in which one field of digital composite video signal selected from every 4 fields is stored successively and second the same as any group successively, combining outputted output together. method according to invention includes steps dividing picture into plurality regions, writing data each point regions corresponding locations only during periods selected, for cycle four fields. Another characterized at least period successive n-fields (n natural number equal or greater than 2).
