PURPOSE:To make it possible to stretch input screen even to a complicated three dimensional object and to obtain special effects of image never experienced before by performing address operation at the write-out side, and by carrying out the interpolation of frame. CONSTITUTION:An input image signal is converted into plural bits of a digital signal by an A/D convertor, and written in memory 14 following a write-address formation circuit 13 after receiving the processing in advance by a low pass filter (LPF)8 and an interpolator 9. Three dimensional address formation circuit 14 stretches an input image signal to a three dimensional object every n frames to form three dimensional addresses X, Y, Z. A frame interpolator 10 interpolates the operated three dimensional addresses X, Y, Z in each n(>1) frame to prepare the data of i frame (n>=i>=1). A fill-up circuit 12 converts two dimensional data after conversion by fluoroscopy into an actual address on the screen. |
