ABSTRACT:
This invention has as its object to provide an image processing apparatus and method, which can re-arrange image data in correspondence with the recording unit used without increasing the capacity of a line memory used in HV conversion, even when the amount of image data to be processed increases to attain a higher resolution. In order to achieve the above object, according to this invention, the following technique is disclosed. Pixel data output from a quantization unit are converted into ID data indicating dot patterns to be converted on the basis of their density values in a representative color table, and thereafter, the arrangement order, in the horizontal direction, of a plurality of ID data is re-arranged in correspondence with the arrangement direction (vertical direction) of nozzles of a recording head.
