A moving image signal decoding apparatus comprises a receiving circuit for extracting a frame code from an inputted signal, a frame decoding circuit for decoding the frame code to obtain a reproduced frame, and a frame interpolating circuit for obtaining an interpolated frame between the reproduced frames.

Why it's free to use
- Filed May 10, 1990 and granted February 15, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 10, 2010.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
