A drowsiness detection apparatus is provided. The drowsiness detection apparatus: an image capturing unit, an alarm apparatus, and a drowsiness determination circuit. The image capturing unit is configured to repeatedly capture a plurality of facial images of a user. The drowsiness determination circuit is configured to obtain an eye region from a current image of the facial images, calculate a vertical histogram of the eye region, and determine an eye part from the eye region according to the vertical histogram. The drowsiness determination circuit further compares the pixel height of the eye part with a closed-eye pixel threshold to perform closed-eye detection, and performs drowsiness detection on the user according to the results of the closed-eye detection. When the result of the drowsiness detection indicates that the user is drowsy, the drowsiness determination circuit transmits a control signal to the alarm apparatus to sound an alarm.
