1. An electronic document generation apparatus generating an electronic document in cooperation with a cloud server which separates a character area in a processing object image for an optical character recognition processing into a plurality of unit recognition areas each of which can include an area larger than a line area for one line and performs said optical character recognition processing on each of said plurality of unit recognition areas, said cloud server generating text data as a processing result of said optical character recognition processing on said processing object image, said text data including a character recognition result for each of said plurality of unit recognition areas and a delimiter code added at the end of said character recognition result for said each of said plurality of unit recognition areas, said electronic document generation apparatus comprising: an extraction part for extracting each of a plurality of line areas from a character area of a scan image of an original; an image generation part for generating a recognition object image by performing an image processing on said scan image so that said each of said plurality of line areas should be determined by said cloud server as a unit recognition area; a transmitting part for transmitting said recognition object image to said cloud server as said processing object image for said optical character recognition processing; a receiving part for receiving said text data which is said processing result of said optical character recognition processing on said recognition object image, from said cloud server; and a document generation part for separating said text data into a plurality of character string data on the basis of said delimiter code included in said text data, determining a correspondence between said plurality of line areas and said plurality of character string data, and generating said electronic document by arranging each of said plurality of character string data in the line area corresponding to said each of said plurality of character string data.
