  • Patent number: 8379095
    Abstract: A method is provided for determining presence of a user's hand tremor or intentional motion during recognition of an image through photographing. Image sample blocks of a previous frame are detected by using an edge detecting method. A block distance between the detected image sample block of the previous frame and an estimated image sample block of a current frame is calculated. The calculated block distance is compared with a first threshold. The calculated block distance is compared with a second threshold when the calculated block distance is less than the first threshold.

  • Patent number: 8355571
    Abstract: Provided is an apparatus and method for generating an image for character region extraction. Upon input of an original image, a candidate character image is generated from the original image and a plurality of binarization maps for similar colors are generated from the generated candidate character image. A binarization map including a background region is selected from among the plurality of generated binarization maps, and the background region of the selected binarization map is expanded. The expanded background region is inverted to generate an image including a character region, thereby generating an image for accurately extracting the character region without missing a boundary portion of a character.

  • Patent number: 8320681
    Abstract: Disclosed is a method and an apparatus for recognizing characters using an image. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

  • Patent number: 8175380
    Abstract: Disclosed are an apparatus and a method for text recognition capability using a camera provided in a mobile communication terminal. Image pre-processing discriminates a text color and a text-background color in an input image, and unifies regions except the text into the text-background color, so that a text region and a background region surrounding the text region can be precisely separated. The image pre-processing method is adaptive to a photographing environment, whereby stable text recognition capability can be expected even if the photographing environment is variously changed.
