20090003707 | IMAGE PROCESSING APPARATUS, IMAGE CAPTURING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM - An image processing apparatus includes an image clipping unit, a feature extracting unit, a candidate identifying unit, and a detecting unit. The image clipping unit clips a window image from a predetermined position of an original image. The feature extracting unit extracts a feature value of the window image on the basis of a predetermined criterion. The candidate identifying unit determines, on the basis of the feature value, whether the window image satisfies a predetermined condition for a candidate including a detection target. The detecting unit determines whether the window image includes the detection target if the window image satisfies the predetermined condition. | 01-01-2009 |

20090096819 | DRIVING CIRCUIT APPARATUS - A driving circuit that reduces chip size of a source driver while maintaining image quality when image data is configured by multiple bits. The source driver provided in connection with a timing controller that converts image data into color data. The source driver displays an image by controlling pixel density of a liquid crystal panel. The source driver is divided into plural regions in units of pseudo linear elements to perform a gamma correcting operation based on a gamma characteristic. In the source driver a GMA voltage for each region is divided by resistive elements arranged between input signal lines. With respect to variation of plural divided GMA voltages, variation of the maximum high density region becomes coarser than variation of the maximum low density region in compliance with visual sensitivity of the density, thus reducing the number of input data lines of the source driver. | 04-16-2009 |
