1. An image processing apparatus comprising:
- encoding means for encoding binary signals and multi-level color signals;
binarization means for converting a muti-level color signal into a binary color signal;
removal means for removing the edge component from the multi-level color signal, using a signal derived from the binary signal produced by said binarization means;
first encoder means for encoding the binary signal from said binarization means and outputting first encoded data;
second encoder means for encoding the muti-level color signal of which edge component is removed by said removal means and outputting second encoded data, andcontrol means for controlling said second encoder means not to output the second encoded data.

Abstract
An image processing apparatus comprising binarization means for converting a multi-level color signal into binary form, removal means for removing edge component from the multi-level color signal, based on a binary color signal from said binarization means, and encoder means for encoding the binary color signal from said binarization means and the multi-level color signal having edge component removed with said removal means.

10. An image processing method comprising the steps of:
-
encoding binary signals and multi-level color signals; converting a multi-level color signal into a binary color signal; removing the edge component from the muti-level color signal, using a signal derived from the binary signal converted in said converting step; a first encoding step of encoding the binary signal converted in said converting step, and outputting first encoded data; and a second encoding step of encoding the muti-level color signal after removal of the edge component in said removing step, and outputting second encoded data, and cont rolling said second encoding step such that the second encoded data is not output in said second encoding step. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
