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