| 20120044387 | IMAGE CORRECTION APPARATUS AND IMAGE CORRECTION METHOD - A line memory stores sequentially image data captured through optical lenses. A distortion correction value storage stores distortion correction values used in the correction of optical distortion occurring in the image data due to distortion aberration present in the optical lens. An image data control unit selects pixels of image data stored in the line memory as pixels to be corrected for the correction of optical distortion respectively. Then the image data control unit determines a region for use in correction, having the fixed number of pixels horizontally and the fixed number of lines vertically, based on the positions of the pixels to be corrected and the distortion correction values obtained from the distortion correction value storage. Here, the region contains a plurality of pixels for use in correction of the pixels to be corrected. Then the image data control unit reads out the image data from the line memory. A distortion correction unit determines pixel values for the pixels to be corrected, based on (1) the pixels for use in correction, which are contained in the image data, within the region for use in correction, and (2) the distortion correction values. | 02-23-2012 |
