摘要： A face detection apparatus and a face detection method thereof are provided. The face detection apparatus includes a rectangle integral image unit, a feature mapping unit and a cascade and score unit. The rectangle integral image unit provides a rectangle integral image according to an original image. The feature mapping unit determines a face candidate region according to rectangular face feature templates, and calculates feature values of the rectangular face feature templates according to the rectangle integral image. The cascade and score unit judges whether the face candidate region conforms to cascade conditions or not, and gives the face candidate region a score according to the feature values when the face candidate region conforms to the cascade conditions. The face candidate region is a non-face region if the score of the face candidate region is lower than a threshold value.

摘要： A determination method for white-point and a correction method of the white balance are disclosed. In the determination method for white-point of the white balance, first gray cards with different reflection coefficients are detected according to the properties of an image sensing device. Next, the white-point gray line of a first color temperature and the white-point gray line of a second color temperature are intersected on a white-point plane to form a fan area, so as to set the white-point range of the low saturation of the image sensing device. Next, the vertical projection for an image datum is calculated to obtain a placement datum on the white-point plane, and a difference value between the image datum and the placement datum is calculated. Finally, whether the image datum is a white-point is determined according to the difference value and relationship between the placement datum and the fan area.
