Abstract

A data processing apparatus having a data analysis circuit for extracting data control information from data provided with the data control information to be used for restricting various processes, a data processing circuit for performing various processes for the data added with the data control information, a display unit for displaying a process function of each of the various processes to be executed by the data processing circuit, and a control circuit for controlling the data processing circuit and the display unit in accordance with the data control information extracted by the data analysis circuit, wherein the control circuit inhibits to execute an inhibited process in accordance with the data control information extracted from the data and controls the display unit to change a display style of the process function of each of the various processes to an inhibition display style.

Claims

1. A data processing apparatus comprising:

data analysis means for extracting data control information from data provided with the data control information to be used for restricting various processes;

data processing means for performing various processes for the data added with the data control information;

display means for displaying a process function of each of the various processes to be executed by said data processing means; and

control means for controlling said data processing means and said display means in accordance with the data control information extracted by said data analysis means,

wherein said control means inhibits to execute an inhibited process in accordance with the data control information extracted from the data and controls said display means to change a display style of the process function of each of the various processes to an inhibition display style.
