PURPOSE:To segment exactly a word from image information which has been read from an original of European language, etc., by deciding a break of a projection of width exceeding a deciding threshold value, to be a gap between words. CONSTITUTION:A vertical projection extracting circuit 20 derives a projection in the vertical direction of sentence line image information which has been inputted from a line buffer 16. Also, to a gap histogram generating circuit 22, information of a vertical projection of one sentence line is inputted from the circuit 20, and a gap histogram is generated by calculating a frequency of width of a break of the vertical projection. This histogram is inputted to a deciding threshold value determining circuit 24, detects the maximum width corresponding to a peak and sends it to a word segmenting circuit 26. The circuit 26 discriminates the break of the vertical projection of width exceeding a word gap deciding threshold value, as an inter-word gap, from the information of the vertical projection which is inputted from the circuit 20, and segments image information of a word which has been delimited by the inter-word gap from the sentence line image information.
