    摘要: A signal processing apparatus includes a signal processing section applying a spatial frequency filter to a pixel signal to perform a signal processing of noise reduction and/or edge enhancement, and a coefficient correcting section setting a coefficient group of the spatial frequency filter to a correct coefficient group. The coefficient correcting section includes an analyzing section, a correspondence section and a coefficient determining section. The analyzing section sets a local area to include an object pixel of the signal processing, and obtains average color information. A correspondence relation between the average color information and the correct coefficient group is set beforehand in the correspondence setting section. The coefficient determining section checks the correspondence relation of the correspondence setting section on the basis of the average color information obtained by the analyzing section, and adjusts the correct coefficient group used for the pixel of the processing object.

    摘要: An electronic camera according to the present invention includes an imaging part, a conditional information determining part, a storage part and a correction processing part. The imaging part images a subject to produce image data. The conditional information determining part determines conditional information that is indicative of the conditions of the subject at a time when the subject is imaged. The storage part stores previous conditional information determined by the conditional information determining part. The correction processing part performs correction processings on the image data, according to both the previous conditional information stored in the storage part and the latest conditional information determined by the conditional information determining part. This enables results of the previous correction processings to be reflected in the current processing, thereby realizing the correction processing with both adaptability and stability.

    摘要: A color photographing device is equipped with a light-receiving section having a red pixel selectively receiving red light and outputting a red pixel signal and a green pixel selectively receiving green light and outputting a green pixel signal. The color photographing device is further equipped with an optical filter disposed on the side with a light-receiving surface of the light-receiving section. The optical filter substantially equalizes the signal level of the red pixel signal and the signal level of the green pixel signal when achromatic color illuminated by a solar light source in the daytime is photographed. Therefore, a white balance gain Wr at about 5000K can be lowered as compared with a conventional color photographing device. Accordingly, reduction of color noises and enhancement of gradation can be expected.

    摘要: The present invention includes a color converting section carrying out color conversion processing and a coefficient correcting section setting a correcting coefficient group to a coefficient group of the color conversion. The coefficient correcting section sets a local area containing a pixel to be processed, and calculates “feature information of the local area” containing at least one of averaged color information, averaged luminance information, and flatness on the basis of the pixel signals of the local area. The coefficient correcting section determines a correcting coefficient group to be used for the pixel to be processed on the basis of the feature information of the local area. With this construction, the present invention suppresses influence of noise when changing the color conversion processing for each pixel.

    摘要: An image processing device of the present invention includes a color-gamut determining part, a color-space determining part, and a color-space conversion part. The color-gamut determining part determines a color gamut as a range of color distribution from input image data. The color-space determining part determines a color space substantially covering the color gamut determined by the color-gamut determining part. The color-space conversion part converts the input image data into such image data that is rendered in the determined color space. The colors of the subject can thus be reproduced accurately from the converted image data.
