| 20100098334 | COLOR-INTERPOLATION DEVICE AND IMAGE PROCESSING SYSTEM - Provided is a color-interpolation device including: an interpolation processor that generates a first interpolated image signal and a second interpolated image signal by respectively performing first interpolation processing and second interpolation processing on a color image signal formed of pixels having a missing color component; an evaluation-value calculating unit that calculates, for each pixel, an evaluation value for specifying a specified region which becomes the target of the first interpolation processing; a region defining unit that defines the specified region on the basis of the evaluation value; and an interpolation-process determining unit that generates the interpolated color image signal by extracting the image signal of the specified region from the first interpolated image signal, extracting the image signal of the region other than the specified region from the second interpolated image signal, and combining the extracted image signals. | 04-22-2010 |
| 20100141809 | IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS, STORAGE MEDIUM FOR STORING IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING METHOD - An image processing apparatus including a noise reducing portion for applying noise reduction to RGB Bayer array image data for each of RGB channels with a noise reduction amount H, and calculating R | 06-10-2010 |
| 20100194934 | IMAGE PROCESSING APPARATUS, PROGRAM, METHOD AND IMAGE CAPTURING SYSTEM - An image processing apparatus with extended dynamic range includes a first gradation-conversion-characteristics calculating unit that calculates first gradation conversion characteristics for each of a plurality of areas of input image signals; and a gradation conversion unit that performs gradation conversion on each of the areas of the image signals by using the first gradation conversion characteristics. A filter processing and reduction processing unit generates a plurality of band signals having mutually different frequency bands by multi-resolution conversion processing from the image signals subjected to the gradation conversion. A second gradation-conversion-characteristics calculating unit calculates second gradation conversion characteristics associated with the individual band signals from the first gradation conversion characteristics An NR processing unit performs processing for noise reduction on the individual band signals by using the second gradation conversion characteristics; and an adding unit combines the band signals subjected to the processing for noise reduction. | 08-05-2010 |
| 20110002539 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM STORING IMAGE PROCESSING PROGRAM - A gradation conversion processor performs gradation conversion processing on image data on the basis of a predetermined gradation conversion characteristic, and a noise reduction processor performs noise reduction processing on the image data. Subsequently, a combining-ratio calculator calculates a combining ratio between the image data before the noise reduction processing performed by the noise reduction processor and the image data after the noise reduction processing on the basis of the gradation conversion characteristic, and a combiner combines the image data before the noise reduction processing performed by the noise reduction processor and the image data after the noise reduction processing on the basis of the combining ratio. | 01-06-2011 |
