Abstract
Image encoding apparatus can operate in a plane sequential encoding mode and in a dot sequential encoding mode. Furthermore, the apparatus may automatically selects any one of these encoding modes or the modes may be selected manually.
Claims30
Image encoding apparatus comprising:
- first encoding means for encoding an image plane sequentially;
- second encoding means for encoding the image dot sequentially;
- and
- selection means for selecting one of said first and second encoding means to provide encoded data.

Image encoding apparatus comprising:
- first encoding means for encoding an image having a plurality of planes by a method in which data of one plane is encoded with reference to other planes;
- second encoding means for encoding the image by a method in which data of one plane is encoded without reference to other planes;
- and
- selection means for selecting one of said first and second encoding means to provide encoded data.
