PURPOSE:To facilitate the checking of misread characters by providing a display color control means and changing the color of picture display of the result of reading by using an evaluation value as a character string. CONSTITUTION:A feature extracting means 2 determines the quantity of feature by using video signals from a scanning means 1. Then, a determining means 3 founds the similarity of characters constituting the character sting by using the quantity of feature and the quantity of feature of reference characters stored in a recognition dictionary 4 and founds the evaluation value of whole character string from the similarity, and sends this evaluation value to a display color control means 6. Then, according to whether the evaluation value is or not a specified value or above, the read character string is displayed in color A and color B respectively on the picture of a display means. For instance, when the evaluation value is less than the specified value, it is displayed in color B and other character string is displayed in color A. In this case, it is enough for an operator to check only character string in color B, and finding of misread character becomes easier compared with the case where all character string on the picture is to be checked.
