摘要

A method for reading a picture is provided which is capable of removing adverse effects caused by lighting conditions or a like. A principal color extracting section extracts principal colors from a color image input by an image inputting section based on a local peak value shown in a color histogram obtained from the color image and divides the color image into principal color images each corresponding to each of the extracted principal colors. A combination creating section creates a combined image by combining separated principal color images. A picture region extracting section extracts character region candidates from the principal color image and combined image. A picture recognizing section performs character recognizing processing on all extracted character region candidates to obtain the best character reading result according to a character recognizing confidence of character recognizing processing results.
