Abstract:
An image coding apparatus for coding an object image by separating a shape representing the outline of said object and a texture representing the pixel values of said object,said image coding apparatus comprising:a first encoder for generating a shape code by coding said shape in slices;a second encoder for generating a texture code by coding said texture in the same slices;a unit for generating a synchronization code for each object image;a data arrangement unit for adding the generated synchronization code with respect to shape codes and texture codes on a frame by frame basis;a first memory for storing a shape code for pixels of at least one slice of a current frame positioned where shape coding for the at least one slice has already terminated;a second memory for storing a texture code for pixels of at least one slice of the current frame positioned where texture coding has already terminated;said first encoder coding a shape associated with a current slice of the current frame by referring to the shape code stored in said first memory;and said second encoder coding a texture of the current slice by referring to the texture code stored in said second memory.
