PURPOSE:To suppress the picture distortion generated due to the quick change of the magnitude of a motion vector. CONSTITUTION:When the magnitude ¦V¦ of a motion vector V detected by a motion vector detecting circuit 13 exceeds a threshold THV outputted from a threshold generating circuit 42, an upper threshold THH of an adaptive motion interpolation switching control circuit 32 is controlled so as to be gradually increased in accordance with the increase of difference DELTAV between them. Then, the inclination of the control characteristic of an adaptive motion interpolation coefficient beta is reduced. As the result, a linear field interpolation signal S2 is selected more easily in comparison with the case that ¦V¦ does not exceed the threshold THV. |
