20090147022 | METHOD AND APPARATUS FOR PROCESSING IMAGES, AND IMAGE DISPLAY APPARATUS - A method and apparatus for processing images, and an image display apparatus are provided that can produce favorable images even when digitized image are partially magnified (enlarged) or reduced (shrunk). The apparatus for expanding or reducing input image data supplied thereto, for each area of the image data, comprises a high frequency (HF) component smoothing processor that generates smoothed-HF-component image data by smoothing HF components of the input image data; a partial magnification/reduction controller that generates partial magnification/reduction control information that designates positions of pixels in image data obtained after expanding or reducing the input image data for each image area; and a pixel data generator that generates pixel data of pixel positions designated by the partial magnification/reduction control information in the smoothed-HF-component image data, by using pixel data in a neighborhood of the designated pixel positions. | 06-11-2009 |
20090175558 | IMAGE PROCESSOR AND METHOD THEREFOR, AND IMAGE DISPLAY DEVICE - An image processor is provided with the high-frequency component detecting unit that calculates a convolution for each of regions of interest in part of an image region of input image data, to output the high-frequency component detection result for each pixel of interest; the smoothing unit that smoothes the image data, to output the smoothed image data; and the image data processing unit that combines based on the high-frequency component detection result the image data with the smoothed image data, to output the combined image data; wherein the image data processing unit varies the combination rate for the smoothed image data, based on the high-frequency component detection result. Thereby, even when a region in the image data contains such high frequency components as a checkered pattern has, an image resistant to moiré that would be generated in magnifying or reducing of the image on a region basis can be displayed without deterioration of image quality. | 07-09-2009 |

20120045148 | IMAGE PROCESSING APPARATUS - An image processing apparatus has an image analyzer including a feature detector, a feature combiner, and a resolution discrimination signal generator. For each pixel in a prescribed area of an input image, the feature detector outputs a representative difference value obtained from the pixel values of pixels positioned, with reference to that pixel, at prescribed intervals. The feature combiner outputs a combined feature value obtained from the representative difference values obtained for each pixel in the described area. The resolution discrimination signal generator outputs a resolution discrimination signal obtained from the combined feature value. The resolution discrimination signal has a monotonic non-decreasing relationship to the combined feature value. The resolution discrimination signal indicates an extent to which the input image includes signal components with frequencies equal to or greater than a particular frequency determined by the prescribed intervals. | 02-23-2012 |
20120121208 | IMAGE PROCESSING DEVICE AND METHOD - To obtain a high resolution image from two or more low resolution images, positional offsets among the low resolution images are determined and the low resolution images are mapped onto a common plane according to the positional offsets. Pixel values in the high resolution image are calculated by weighted interpolation from the pixel values of the low resolution images, using interpolation coefficients that increases with increasing correlation with the pixel of interest. Correlation is determined by taking horizontal and vertical first and second derivatives of the pixel values in one low resolution image to find a direction of strong correlation. Appropriate interpolation is thereby obtained even near edges and other abrupt changes in the image. | 05-17-2012 |
20130121611 | IMAGE PROCESSING DEVICE AND METHOD AND IMAGE DISPLAY DEVICE - An image processing device includes an edge-enhancing image enlarger that converts an input image to a high-resolution image with edge enhancement. A difference calculator determines differences between the high-resolution image and the input image. A high-resolution image corrector corrects the high-resolution image by diffusing the differences to pixels of the high-resolution image, thereby generating a corrected image in which edges are enhanced without image degradation in textured areas. | 05-16-2013 |
