    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: A plurality of photography operations are performed with respect to a single subject with different photography conditions, to obtain a plurality of image data sets. The obtained image data are processed to obtain a single dynamic range expanded image data set. A photography method is selected from among: a first method, in which photography is performed at least twice at different exposures; a second method, in which photography is performed with an underexposure at a step number based on a set dynamic range; and a third method, in which photography is performed at least twice with different underexposures at step numbers based on a set dynamic range, based on whether photography operations are possible at exposure ratios corresponding to the expansion ratio of the dynamic range and whether flash is emitted. Photography is performed according to the selected method, thereby preventing limitations of dynamic range due to hardware specifications.
