ABSTRACT:
On processing an input picture into a processed picture in compliance with an input concatenated-command, a command editing unit edits the input concatenated-command into an edited concatenated-command which is equivalent in function to the input concatenated-command and is less in length than the input concatenated-command. A command executing unit executes the edited concatenated-command for the input picture to produce the processed picture. Preferably, the command editing unit has a dividing unit which processes the input concatenated-command into a succession of elementary commands. A combining unit combines the elementary commands into the edited concatenated-command by deleting, from the succession of the elementary commands, a succession of a particular elementary command and an inverse elementary command which immediately succeeds the particular elementary command and is inverse in function to the particular elementary command. Alternatively, the combining unit may produce the edited concatenated-command by substituting an equivalent elementary command for a succession of a specific elementary command and a succeeding elementary command which immediately succeeds the specific elementary command and is equivalent in function to the succession of the specific and the succeeding elementary commands. The input concatenated-command is typically a concatenation of input commands, each of which is greater in length than each elementary command.
