Abstract: This invention provides a camera image recognition apparatus capable of moving a camera to read a wide region of a document at a high precision and easily correcting an erroneously recognized portion. The shift amount of the character string image of a document image to be compared is calculated for each sensed document image from the character string image of a specific document image among a plurality of sensed document images. When the calculated shift amount reaches a predetermined amount, a new character image in the character string image of a document image whose shift amount reaches the predetermined amount is composited to the character string image of the specific document image, thereby generating a document image.
