PURPOSE:To save current consumption and to reduce the number of external circuits by outputting an inverted address signal obtained by inversing a 1st address signal and selecting and outputting partially the 1st address signal and the inversed address signal. CONSTITUTION:An inverting circuit 6 finds out the complement of an address only at a frame conversion part out of address in the 1st reading address 103 and forms and outputs 1 2nd reading address 104. A 1st selector 7 inputs the 1st and 2nd reading addresses 103, 104, selects the 2nd reading address 104 at the frame conversion part and the 1st reading address 103 at the other part and outputs 3rd reading address 105. Thus, the complement of only the address requiring frame connersion can be be found out. Consequently, an economical frame conversion circuit having a wide application range can be constituted. |
