ABSTRACT:
An automatic exposure control apparatus comprises a skin color extracting circuit for extracting a skin-colored portion from an input video signal and a focus condition detecting circuit for detecting a focus condition of the skin-colored portion. Exposure is controlled based on outputs of the two circuits. That is, when a skin-colored portion is extracted and it is detected that the skin-colored portion is in an in-focus condition, exposure is controlled so as to be appropriate with respect to the skin-colored portion. A skin color correction unit can correct colors corresponding to the skin color from the video signal.
