摘要： Noise reduction processing in accordance with frequency band is executed. To accomplish this, a image data dividing circuit divides image data into image data having frequencies in a low-frequency region, image data having frequencies in a low- to intermediate frequency region and image data having frequencies in a low- to high-frequency region. These items of image data thus divided on a frequency-band basis are input to respective ones of noise reduction circuits that have been set to respective ones of parameters suited to noise reduction of image data having frequencies in the low-, low- to intermediate and low- to high-frequency regions, respectively. The items of image data that have thus undergone noise reduction processing conforming to frequency band are input to an image data combining circuit. The latter combines the image data so as to obtain image data representing one frame of an image.

摘要： CCD-RAW data obtained by sensing the image of a subject is applied to a first noise reduction circuit via a offset correction circuit, a gain correction circuit, a linear matrix circuit and a gamma correction circuit. Uncorrelated noise is removed from the CCD-RAW data in the first noise reduction circuit. The CCD-RAW data is subjected to synchronization (color interpolation) in the synchronization processing circuit, and luminance data Y and color difference data C is generated by an RGB-YC conversion circuit. The generated luminance data Y and generated color difference data C is subjected to noise reduction processing on a per-frequency-component basis in the second noise reduction circuit. Suitable noise reduction processing conforming to the state of image data before and after synchronization processing is executed.

摘要： Tristimulus values of each of pixels in an image, which is represented by an image signal, are transformed into chromaticity values, and mean values of the chromaticity values having been calculated with respect to the pixels in the image are calculated. The mean values of the chromaticity values are transformed into physiological primary colors. The thus obtained physiological primary colors are regarded as the white of a photographing illuminant, under which a photographing operation was carried out. The chromaticity values are transformed such that the thus obtained physiological primary colors may coincide with the physiological primary colors of a reference photographing illuminant. The chromaticity values, which have been obtained from the transformation, are then transformed into RGB color signals. The thus obtained RGB color signals are subjected to image processing and then used for reproducing a visible image.
