Abstract: PURPOSE: To improve the quality of a final output picture by giving capability to execute different processing for different data type to a post-processing device. CONSTITUTION: A first data generator A20 and a second data generator B22 are connected to a discriminative encoder 24. The output of the discriminative encoder 24 is coupled to the input of a frame storage device 26, and the output of the frame storage device 26 is coupled to the input of a post-processing discriminator 28. The output of the post-processing discriminator 28 is divided in conformity to the generation source of data stored in the frame storage device 26. The data generated from the data generator A20 is coupled to the input of a data converting device A30, and the data generated from the data generator B22 is coupled to the input of the data converting device B32. The output of the data converting device A30 and the data converting device B32 is coupled to the input of a marking device 34. Thus, the sharp text output of high contrast and the output of a continuous gray scale excellent in the viewpoint of visual sensation can be obtained from the marking device 34.
