An apparatus and method for compensating for a black level in order to solve a screen flickering phenomenon and a problem of convergence speed of a black level value. The apparatus for compensating for a black level includes: a black pixel average value extraction unit averaging black pixel values of a current frame to determine a black pixel average value; a luminance value extraction unit extracting a luminance value from an analog gain and concentration time information of an image sensor; a black level extraction unit calculating a frame weight by using the luminance value and acquiring a black level value of a current frame by using the frame weight, the black pixel average value, and a black level value of a previous frame; and a black level compensation unit compensating for valid pixel values of the current frame by using the black level value of the current frame. |
