Patent ID: 7936371

Claim:
An image-taking apparatus comprising: an image-taking section which carries out image-taking by using an image pickup element; a first control section which, in a calibration mode, successively shifts a value of a parameter relating to white balance and makes the image-taking section take a plurality of images with parameters different from each other; a second control section which, in the calibration mode, stores a correction amount relating to the parameter corresponding to an image selected by a user among the plurality of images in a memory, together with a lens information of the image-taking apparatus; a determination section which, in a normal image-taking mode, determines whether or not the memory stores the correction amount relating to the parameter according to an attached lens in accordance with the lens information stored in the memory; and a third control section which, in the normal image-taking mode, corrects white balance of an image taken by said image-taking section on the basis of the correction amount relating to the parameter, wherein when it is determined that the memory stores the correction amount relating to the parameter according to the attached lens, said third control section corrects white balance of the image taken by said image-taking section on the basis of the correction amount relating to the parameter stored in the memory, and when it is determined that the memory does not store the correction amount relating to the parameter according to the attached lens, said third control section corrects the white balance of the image taken by said image-taking section on the basis of a different correction amount relating to the parameter from the correction amount relating to the parameter stored in the memory.
