<p>PURPOSE:To perform the displacement of a digital picture, the MTF compensation and the gradation compensation at one time, by using the same space data. CONSTITUTION:The picture signal D.IN which is sampled with every picture element and equalized is delayed by a degree equivalent to a line directly or via plural line buffers LB1-LB3 to be fed to space registers S1-S16. Thus the space data S.DATA is extracted within a specific picture element region. At the same time, the position state of a noticed picture element, i.e., an object of process is calculated by a calculating circuit and from the line synchronizing signal L.SYNC and the picture element clock CLK. Then the data is altered by the state signal SS and the data S.DATA and in accordance with the contents of process (process designating signal PC) which is designated by a data converting circuit 2. As a result, the varying magnification of a digital picture, the MTF compensation and the gradation compensation are carried out at one time.</p> |
