Abstract

To provide a method for controlling the display of a screen which allows the user to discriminate the scanned image and the recognition result intuitively and easily. The display control method for allowing the user to verify the recognition result of a character on a verification screen form 300 is implemented as follows. First of all, the standard pattern of a specific character stored in a memory and a plurality of character images recognized as the specific character are read, upon an operation of the user. And the read standard pattern is displayed in a recognition result character display portion 310 within the verification screen form 300 and a plurality of the read character image are displayed sequentially in a character image display portion 320 adjacent or proximal to the recognition result character display portion 310 and at a predetermined position of a character image list display portion 330 . A plurality of character images are listed in the character image list display portion 330 , in which the already displayed character images are shifted one position from the predetermined position and displayed.
