PURPOSE: A milling deviation measurement method and device are provided to measure a milling degree by measuring a color rice bran area rate index of a rice specimen without NMG reagent processing, thereby simply and rapidly measuring rice bran remained in the rice specimen. CONSTITUTION: A milling deviation measurement device includes a transparent plate (110), a backlighting unit (220), ring lighting (210), an image acquisition unit (300), and an image processing unit (400). A milled rice specimen is placed on the transparent plate. The backlighting unit is arranged under the transparent plate and irradiates lights to the rice specimen placed on the transparent plate. The ring lighting is arranged above the transparent plate and irradiates lights to the rice specimen through a ring-shaped diffuser. The image acquisition unit acquires reflection images formed by the lights irradiated from the ring lighting and reflected by the rice specimen and transmission images formed by the lights irradiated from the backlighting unit and penetrated through the rice specimen. The image processing unit detects a residual rice bran region based on the reflection images and the transmission images acquired by the image acquisition unit, thereby calculating a color rice bran area rate (CBB) index after acquiring a pericarp region and an aleurone layer region.
