An image coding apparatus and method code an object image by separating the object image into a shape representing the outline of the object image and a texture representing the pixel values of the object image. The coded object image is decoded by an image decoding apparatus and method adapted for the image coding apparatus and method. The image decoding apparatus and method generate a shape code by coding the shape in predetermined units, generate a texture code by coding the texture in predetermined units, and generate a synchronization code with respect to the shape code for each predetermined unit and the texture code for each predetermined unit. The generated synchronization code is added to the shape code for each predetermined unit and the texture code for each predetermined unit, which thus provides codes enabling restoration from an erroneous condition.
