Claims
4. A moving image signal encoding apparatus according to claim 2, wherein said interpolated frame encoder includes a subtractor for obtaining a difference between said interpolated frame and a corresponding frame of said input moving image signal, and an error encoder for encoding said difference to obtain an interpolated frame code.
5. A moving image signal encoding apparatus according to claim 2, wherein said interpolated frame encoder includes: a subtractor for obtaining a difference between said interpolated frame and a corresponding frame of said input moving image signal; an error calculator for obtaining a value of said difference; an encoded area selector for determining an area for encoding said difference by an output of said error calculator, and an encoder for encoding said difference by using an output of said encoded area selector to obtain an interpolated frame code.
