Abstract
Converting text may be provided. A user selectable element may be used to select a text. The selected text may include a first text within an electronic document and a second text within an image. The second text within the image may be converted to character information by receiving the image. The image may have image character information and an image type. An aspect of the received image may be adjusted based on the image type. Optical character recognition may be performed on the adjusted image to extract character information. The character information may include characters and corresponding location information for the characters. The extracted character information may be evaluated to improve the recognition quality of the extracted character information as compared to the image character information.
