Imaging pickup apparatus, image pickup method, image processing apparatus, image processing method, and image processing program
First Claim
1. An image pickup apparatus for picking up an image by using a solid-state image sensing device, the image pickup apparatus comprising:
- a color component acquiring unit that acquires picked-up-image color-component signals representing color components of the picked-up image;
a face detecting unit that detects a face from the picked-up image;
a skin-color-region color-component acquiring unit that, when the picked-up image includes a face, acquires skin-color-region color-component signals based on a face detection result;
a skin-color-eliminated-component-signal-information creating unit that creates skin-color-eliminated component-signal information obtained by eliminating the skin-color-region color-component signals, obtained by the skin-color-region color-component acquiring unit, from the picked-up-image color-component signals obtained by the color component acquiring unit;
a white-balance-gain setting unit that sets a white balance gain by using the skin-color-eliminated component-signal information; and
a white balance control unit that performs white balance adjustment of the color components of the picked-up image by using the white balance gain.
