Abstract
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.
