    Abstract: A semiconductor device including a comparison circuit configured to receive an input signal having n signal levels, where n is a natural number equal to or greater than three, and output n−1 first signals having two signal levels. The device includes a jitter compensation circuit configured to receive the n−1 first signals and compensate for at least one of a length of a period in which a signal level of at least one of the n−1 first signals transitions from a first signal level to a second signal level different from the first signal level, and a length of a period in which the signal level of the at least one of the n−1 first signals transitions from the second signal level to the first signal level, to output n−1 second signals.

    Abstract: A reference voltage generating circuit includes: an operational amplifier including a first input terminal connected to a first node and a second input terminal connected to a second node; a first transistor connected between a ground terminal and the first node, wherein a first current flows in the first transistor; a second transistor connected to the ground terminal; and a first variable resistor connected between the second transistor and the second node, wherein the first variable resistor has a first resistance value for adjusting the first current, based on a change in a current characteristic of the first transistor caused by a variation in a process of forming the first transistor. The reference voltage generating circuit provides a reference voltage, based on a voltage of the first node and a voltage across the first variable resistor.

    Abstract: A method and an apparatus for recognizing characters using an image are provided. 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.

    Abstract: An apparatus and a method for recognizing a character based on an input image is provided. The apparatus includes an input unit configured to receive the input image and a controller configured to select, from the input image, a region of image analysis to be used for image analysis, and to analyze the selected region of image analysis to determine a type of the input image, to apply, to the input image, an image effect for distinguishing a character region and a background region in the input image if the type of the input image indicates that the input image is obtained by photographing a display screen, to binarize output of the image effect according to the determined type of the input image, and to recognize a character from the binarized output of the image effect.
