5. An automatic scoring system, comprising:
a database;
a photographing device configured to capture a current test paper image and outputting the current test paper image, wherein a hand-writing script on the current test paper image has a script color; and
a processing device connected to the database and the photographing device, and configured to obtain the current test paper image,
determine whether the script color is a designated color,
determine whether the database stores a reference text string if the script color is not the designated color,
align the current test paper image with a reference test paper image corresponding to the reference text string and use a plurality of reference coordinates to compare the current test paper image with the reference test paper image to output a test score when the database stores the reference text string, and
identify the hand-writing script to store an identification result as the reference text string and store a plurality of position coordinates of the hand-writing script on the current test paper image as the plurality of reference coordinates if the script color is the designated color.
