    Abstract: A reconfigurable bipolar output charge pump circuit includes an input terminal configured to receive an input voltage. First and second terminals are connected to a first flying capacitor, and third and fourth terminals are connected to a second flying capacitor. First and second output terminals are respectively connected to first and second output capacitors and configured to respectively provide a positive output voltage and a negative output voltage. A switch network includes switches configured to connect the input terminal, the first to fourth terminals, and the first and second output terminals to each other in response to switch control signals. The switch network is configured to provide one of multiple potential charge pump modes. A controller generates the switch control signals in response to a mode control signal indicating one of the charge pump modes so that a magnitude of the positive output voltage and the negative output voltage becomes one of multiple predefined voltage levels.

    Abstract: An apparatus and method for recognizing a character based on a photographed image. The apparatus includes an image determining unit, an image effect unit, a binarizing unit and a character recognizing unit. The image determining unit is configured to select, from an input image, a Region Of Interest (ROI) to be used for image analysis when the input image is input, and to analyze the selected ROI to determine a type of the input image. The image effect unit is configured to apply to the input image, an image effect for distinguishing a character region and a background region in a display screen if the type of the input image indicates that the input image is obtained by photographing a display screen. The binarizing unit is configured to binarize the input image or the output of the image effect unit according to the determined type of the input image. The character recognizing unit is configured to recognize a character from the binarized input image.
