Abstract

PURPOSE: To convert an image signal into a signal matching an image display unit which is different in scanning form and scanning period by rearranging respective lines of both fields obtained by interlaced scanning to a sequential scanning form and calling them in order synchronously with the sequential scanning of an image display. CONSTITUTION: Image information 2 obtained by interlaced scanning through a television camera 1, etc., has its odd field components 4 and even field components 5 decided by an odd/even field detecting means 3, pieces of image information of the field components 4 and 5 are stored in a couple of frame memories 6 and 7, and image information of each line is read alternately out of them in order by an image information read means 8. For the reading operation of the image information read means 8, the selection of the frame memories for image display for image display is synchronized by a read synchronizing means 11 with the switching of fields of interlaced scanning. Consequently, an image display unit for a computer is diverted to the display of a composite image as it is, so the image information of interlaced scanning can be converted into image information of sequential scanning.
