1. A video processing apparatus that detects biometric information of an object from a video of the object composed of a plurality of time-series images, the apparatus comprising:
an acquiring unit configured to receive the video input thereto, and acquire a skin area of an object;
a determining unit configured to determine correction coefficients based on a color of the skin area acquired by the acquiring unit and a color indicating a target hue, the correction coefficients being for approximating a hue of pixels in the skin area acquired by the acquiring unit to the target hue;
a correcting unit configured to correct, with use of the correction coefficients, at least the pixels in the skin area in each of the frames composing the video; and
a detecting unit configured to detect biometric information of the object based on time-series images of the skin area after the correction by the correcting unit.
