A biometric image processing apparatus comprising: a pixel value obtainment unit that obtains, from each of a plurality of pixels of an image, a Y value, a U value and a V value of the pixel in a YUV space, where the image is an image of a palm; a determination unit that determines, for each of the plurality of pixels, whether or not the U value of the pixel is in a first range calculated by using the Y value of the pixel, and whether or not the V value of the pixel is in a second range calculated by using the Y value of the pixel labels, as a first area, a pixel from among the plurality of pixels for which the U value has been determined to be in the first range and the V value has been determined to be in the second range, and labels, as a second area, a pixel from among the plurality of pixels for which the U value has been determined to not be in the first range or the V value has been determined to not be in the second range; and a biometric image extraction unit that extracts, from the image, the pixel labeled as the first area from among the plurality of pixels, wherein maximum value Umax of the first range is calculated by assigning the Y value of the pixel to the following equation: Umax = − 0.0043 Y 2 + 0.9564 Y + 137.18, minimum value Umin of the first range is calculated by assigning the Y value of the pixel to the following equation: Umin = 0.0004 Y 2 − 0.251 Y + 130.64 maximum value Vmax of the second range is calculated by assigning the Y value of the pixel to the equation: Vmax = − 0.0033 Y 2 + 0.8317 Y + 126.43 and minimum value Vmin of the second range is calculated by assigning the Y value of the pixel to the equation: Vmin = 0.0011 Y 2 − 0.2152 Y + 134.48 a pixel value obtainment unit that obtains, from each of a plurality of pixels of an image, a Y value, a U value and a V value of the pixel in a YUV space, where the image is an image of a palm; a determination unit that determines, for each of the plurality of pixels, whether or not the U value of the pixel is in a first range calculated by using the Y value of the pixel, and whether or not the V value of the pixel is in a second range calculated by using the Y value of the pixel labels, as a first area, a pixel from among the plurality of pixels for which the U value has been determined to be in the first range and the V value has been determined to be in the second range, and labels, as a second area, a pixel from among the plurality of pixels for which the U value has been determined to not be in the first range or the V value has been determined to not be in the second range; and determines, for each of the plurality of pixels, whether or not the U value of the pixel is in a first range calculated by using the Y value of the pixel, and whether or not the V value of the pixel is in a second range calculated by using the Y value of the pixel labels, as a first area, a pixel from among the plurality of pixels for which the U value has been determined to be in the first range and the V value has been determined to be in the second range, and labels, as a second area, a pixel from among the plurality of pixels for which the U value has been determined to not be in the first range or the V value has been determined to not be in the second range; and a biometric image extraction unit that extracts, from the image, the pixel labeled as the first area from among the plurality of pixels, wherein maximum value Umax of the first range is calculated by assigning the Y value of the pixel to the following equation: Umax = − 0.0043 Y 2 + 0.9564 Y + 137.18, minimum value Umin of the first range is calculated by assigning the Y value of the pixel to the following equation: Umin = 0.0004 Y 2 − 0.251 Y + 130.64 maximum value Vmax of the second range is calculated by assigning the Y value of the pixel to the equation: Vmax = − 0.0033 Y 2 + 0.8317 Y + 126.43 and minimum value Vmin of the second range is calculated by assigning the Y value of the pixel to the equation: Vmin = 0.0011 Y 2 − 0.2152 Y + 134.48
