In an image processing apparatus and method, such a problem that the user must wait for a long time until region separation processing is completed is solved. A binary-coding unit performs binary coding of a luminance component of input color-image data. An encoding unit performs arithmetic encoding of the binary image data, and another encoding unit performs block encoding of the color-image data, and codes obtained from the two encoding units are stored in different storage units. A predetermined pair of codes read from the storage unit are decoded by decoding units. A region discrimination unit discriminates image regions of decoded binary image data, and outputs data of character-line-drawing regions. A color-gradation-image extraction unit extracts data of color-gradation-image regions from decoded color-image data.
