Digital device and method for monitering driver thereof

Relates to a digital device capable of sensing the condition of the driver and his driver monitoring method, the first, second, comprising the steps of: acquiring an image from the camera unit, the brightness of the image obtained from the first camera unit or more than a reference value or 2 and to determine whether the driver is detected from the obtained from the camera sub-image, a result of the check, the first camera portion, the brightness of the image is not more than a reference value obtained from, or the second driver is detected from the image obtained from the camera unit If not, a second turning off (off) of the illumination portion to obtain a first comparison image from a first camera module, and the second turning on (on) of the illumination portion and obtaining a second comparative image from the first camera unit, acquisition a first comparison a first comparison image brightness and acquiring the second comparative image confirmation and confirming whether the differential value is more than the reference differential value of the brightness, as a result, the Brightness and the differential value of the brightness of the second image of the comparative image is not more than the reference differential value, it can be made, including the step of turning off the second illumination portion.
