PROBLEM TO BE SOLVED: To provide a half tone processor which can get a high-quality half tone image high in reproducibility, and can finish the processing in a short time, and a medium having recorded its procedure. SOLUTION: These are a half tone processor consisting of a block dividing means which divides a input image into blocks consisting of specified size of picture elements, an adaptation computing means which makes the picture element of each block a vector and compares this with a code word to serve as a candidate of conversion and computes the adaptation, and an image generating means which generates an image in the block, based on the code word where the adaptation is maximum, and a storage medium having recorded its procedure.
