PURPOSE:To attain sure still display even to a moving picture part by introducing an interpolation data in a field or an inter-frame interpolation data selectively during the still picture reproducing period. CONSTITUTION:In throwing a still picture switch S1 for moving picture to the position of earth, a low level voltage is inputted to a changeover switch 3, a mixing ratio switching circuit 8 and a memory control circuit 2. As a result, the memory control circuit 2 inhibits the write in the timing when the AD conversion is finished in the video period and only the readout is executed without changing the write state of memories M1-M4. Moreover, the changeover switch 3 is thrown to the position of a 1st memory M1, to form the inter-field interpolation data by the read data of the 1st memory M1. Moreover, the mixing rate changeover circuit 8 sets the mixing ratio of the inter-frame interpolation data in the mixing circuit 7 and inputs only the in-field interpolation data to a TCI decode circuit 9. Thus, even when the moving picture is in stand still, the still picture reproduction is applied by the in-field interpolation data without flair.
