Abstract
An image processing method for balancing colors of an image on the basis of the principle of the color constancy. The image processing method for processing an image photographed by a photographing apparatus, has: converting a color data of the image photographed by the photographing apparatus under a different type light source, so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source, against a standard light source color data which is a color data for the color chips under the standard light source.
Claims25
An image processing method for processing an image photographed by a photographing apparatus, comprising:
- converting a color data of the image photographed by the photographing apparatus under a different type light source, so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source, against a standard light source color data which is a color data for the color chips under the standard light source.
An image processing apparatus for processing an image photographed by a photographing apparatus, comprising:
- a converter for converting a color data of the image photographed by the photographing apparatus under a different type light source, so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source, against a standard light source color data which is a color data for the color chips under the standard light source.
An image processing system comprising:
- a first image processing apparatus comprising a data storage for storing a data, by storing at least one of a processed image data obtained by converting a color data of a photographed image data photographed by a photographing apparatus under a different type light source so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source against a standard light source color data which is a color data for the color chips under the standard light source, and the photographed image data, and at least one of a conversion data capable of specifying a converting method for converting the photographed image data to the processed image data, and an address data indicating an address of the conversion data;
- a second image processing apparatus for processing an image, by converting a color data of a photographed image data photographed by a photographing apparatus under a different type light source so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source against a standard light source color data which is a color data for the color chips under the standard light source;
- and
- a transmission medium for exchanging a data between the first image processing apparatus and the second image processing apparatus;
- wherein the system sends at least one of the photographed image data and the processed image data stored in the data storage, and at least one of the conversion data and the address data stored in the data storage, from the first image processing apparatus to the second image processing apparatus, through the transmission medium.
A data structure of an image data file having an image data recorded thereon, comprising:
- a first data area comprising the image data;
- and
- a second data area capable of being referenced by an image processing apparatus, corresponding to any one of a conversion data for converting a color data and an address of the conversion data.
An image processing method for processing an image photographed by a photographing apparatus, comprising:
- converting a color data of the image photographed by the photographing apparatus under a different type light source, on the basis of a conversion data capable of converting at least one different type light source color data which is a color data for color chips including a chromatic color, obtained based on a data concerning spectral sensitivities of the photographing apparatus, under at least one different type light source which is different from a standard light source, so as to adapt against a standard light source color data which is a color data for the color chips under the standard light source.
