Title: Picture matching system
Inventor: WATANABE YUTAKA
IPC: H04N13/00
Filed: 1989-02-06
Abstract: PURPOSE:To assume the change of brightness and contrast with the use of a detected displacement quantity by detecting the displacement of a discrete picture by means of the inverse conversion of the phase difference of a Fourier transformation coefficient. CONSTITUTION:Discrete input pictures 1 and 2 at two frames are respectively Fourier-transformed by Fourier transformation circuits 3 and 4, the difference between phase items 5 and 6 of the Fourier coefficient is obtained by a phase difference calculating circuit 7, and inversely converted again by a inverse Fourier transformation circuit 8. Next the input picture (X) 2 is shifted by a displacement quantity alpha by a data shift circuit 10. Shifted data 11 and the input picture (Z) 1 to be the other original data are inputted to a brightness/ contrast assuming circuit 12. In the brightness/contrast assuming circuit, respective assumed values 13a and 14a of the brightness and contrast are calculated and outputted. Thus the assumption of a motion vector including the assumption of a brightness change in time and the assumption of the parallax vector between stereo pictures including the assumption of a spatial brightness change can be correctly executed.
