An electronic document generation apparatus generates a recognition object image by performing an image processing on a scan image so that each of a plurality of line areas extracted from a character area of the scan image should be determined as a unit recognition area and transmits the recognition object image to the cloud server. The apparatus further receives text data which is a processing result of an optical character recognition processing on the recognition object image, in which a delimiter code is added at the end of a character recognition result for each of a plurality of unit recognition areas, from the cloud server, separates the text data into a plurality of character string data on the basis of the delimiter code, and generates an electronic document by arranging each of the plurality of character string data in the line area corresponding to each character string data.
