ABSTRACT:
An image processing apparatus includes an image input device for photoelectrically converting a document image which has been optically read and for inputting the converted document image as image data. An area separator separates a plurality of areas included in the input image data from one another and a character recognition is performed from a plurality of directions with respect to character data in the image data input by the image input device with reference to a character recognition dictionary. The apparatus performs a first discriminating function of discriminating, for the plurality of areas separated by the area separator, respective reliabilities in a plurality of directions on the basis of results of the character recognition, and second discrimination function for discriminating a document direction on the basis of average values of the reliabilities discriminated by the first discriminating function.
