Image coding method and apparatus |
November 6, 2007 |
| A motion detection block includes a wavelet transform section which receives a current image I1 and a reference image I2 as inputs. The motion detection section detects a motion vector using size-reduced images RI1 and RI2 generated by transform in the wavelet transform section. Thus |

Encoding device and encoding method for changing code amount of compressed image data |
May 14, 2002 |
| Compressed image data from a code memory is separated into quantization step values, code table information and variable-length codes. The variable-length codes are each decoded into a run length, a size and an additional bit string and written into a size memory. A size conversion s |
