Abstract:
Provided is a dot area extraction method including extracting a first dot area in binary data based on periodicity of pixels for every first range by dividing the binary data in a first direction or a second direction in the first range which includes a first number of pixels in the first direction and a second number of pixels in the second direction, and extracting a second dot area in the binary data based on the periodicity of the pixels for every second range by dividing the binary data in the first direction or the second direction in the second range which includes a third number of pixels in the first direction and a fourth number of pixels in the second direction.
