An area discrimination system discriminates areas from each other in a binary image. The system includes a reducing unit for reducing a binary image supplied from an external unit, a skew detector for detecting skew of the binary image with respect to a predetermined direction, an extracting unit for extracting black connected components from the reduced image, a block forming unit for forming blocks, each of which includes a plurality of black connected components close to each other, a first merging unit for merging blocks satisfying first conditions into a a character string by using of the skew detected by said skew detector, the first conditions including at least a condition depending on skew of the binary image, and a second merging unit for merging character strings satisfying second conditions into a column by using of the skew detected by said skew detector, the second conditions including at least a condition depending on skew of the binary image.
