Abstract
Abstract When carrying out further color balance adjustment processing on color-balance adjusted image data having been through color balance adjustment processing, processing performance of the further color balance adjustment processing is sufficiently used. In a digital camera, by carrying out processing such as first AWB processing and chroma enhancement processing on original image data obtained by photographing, output image data are obtained. The output image data are then input to a printer. In the printer, processing which is the inverse of processing carried out in processing means of the digital camera and inverse AWB processing which is the inverse of the first AWB processing is carried out on the output image data, and inverse AWB image data which can be regarded as the original image data are obtained. Processed image data are then obtained by carrying out second AWB processing different from the first AWB processing on the inverse AWB image data, and a print is generated by output means based on the processed image data.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
An image processing method for obtaining color-balance adjusted image data by carrying out color balance adjustment processing on white-balance adjusted image data obtained by carrying out, on original image data, white balance adjustment processing using gain adjustment in a color space in which the original image data have been obtained, the image processing method comprising the steps of: obtaining inverse white-balance adjusted image data by carrying out, on the white-balance adjusted image data, inverse white balance adjustment processing which is inverse processing of the white balance adjustment processing; and obtaining the color-balance adjusted image data by carrying out the color balance adjustment processing on the inverse white-balance adjusted image data.
Claim 2
Dependent Claim
110 words
An image processing method for obtaining color-balance adjusted image data by carrying out color balance adjustment processing on white-balance adjusted image data obtained by carrying out, on original image data, white balance adjustment processing using gain adjustment in a color space in which the original image data have been obtained, the image processing method comprising the steps of: obtaining inverse white-balance adjusted image data by carrying out, on the white-balance adjusted image data, inverse white balance adjustment processing which is inverse processing of the white balance adjustment processing; and obtaining the color-balance adjusted image data by carrying out the color balance adjustment processing on the inverse white-balance adjusted image data.
Claim 3
Dependent Claim
37 words
An image processing method as defined in claim 1 , wherein the inverse white balance adjustment processing is carried out on the white-balance adjusted image data, based on information when carrying out the white balance adjustment processing.
Claim 4
Dependent Claim
117 words
An image processing apparatus for obtaining color-balance adjusted image data by carrying out color balance adjustment processing on white-balance adjusted image data obtained by carrying out, on original image data, white balance adjustment processing using gain adjustment in a color space in which the original image data have been obtained, the image processing apparatus comprising: inverse processing means for obtaining inverse white-balance adjusted image data by carrying out, on the white-balance adjusted image data, inverse white balance adjustment processing which is inverse processing of the white balance adjustment processing; and color balance adjustment processing means for obtaining the color-balance adjusted image data by carrying out the color balance adjustment processing on the inverse white-balance adjusted image data.
Claim 5
Dependent Claim
117 words
An image processing apparatus for obtaining color-balance adjusted image data by carrying out color balance adjustment processing on white-balance adjusted image data obtained by carrying out, on original image data, white balance adjustment processing using gain adjustment in a color space in which the original image data have been obtained, the image processing apparatus comprising: inverse processing means for obtaining inverse white-balance adjusted image data by carrying out, on the white-balance adjusted image data, inverse white balance adjustment processing which is inverse processing of the white balance adjustment processing; and color balance adjustment processing means for obtaining the color-balance adjusted image data by carrying out the color balance adjustment processing on the inverse white-balance adjusted image data.
Claim 6
Dependent Claim
40 words
An image processing apparatus as defined in claim 3 , wherein the inverse processing means carries out the inverse white balance adjustment processing on the white-balance adjusted image data, based on information when carrying out the white balance adjustment processing.
Claim 7
Dependent Claim
121 words
A computer-readable recording medium storing a program to cause a computer to execute an image processing method for obtaining color-balance adjusted image data by carrying out color balance adjustment processing on white-balance adjusted image data obtained by carrying out, on original image data, white balance adjustment processing using gain adjustment in a color space in which the original image data have been obtained, the program comprising the procedures of: obtaining inverse white-balance adjusted image data by carrying out, on the white-balance adjusted image data, inverse white balance adjustment processing which is inverse processing of the white balance adjustment processing; and obtaining the color-balance adjusted image data by carrying out the color balance adjustment processing on the inverse white-balance adjusted image data.
Claim 8
Dependent Claim
121 words
