Patent number: 10321014Abstract: An image reading unit reads a source document image in 600 dpi, and a resolution conversion unit converts the resolution of the image to 75 dpi. An inclination detection unit detects inclination of the source document image. When a character conversion unit is to execute character recognition after cropping, a mode setting unit sets a quality-first mode. The inclination correction unit corrects the inclination of the image of 600 dpi, according to the inclination of the source document image detected by the inclination detection unit. A document image clipping unit clips out the source document image, and the resolution conversion unit converts the resolution of the source document image to 200 dpi. Thereafter, the character conversion unit executes the character recognition.Type: GrantFiled: August 25, 2016Date of Patent: June 11, 2019Assignee: KYOCERA Document Solutions Inc.Inventors: Yuya Tagami, Hiroyuki Harada
