ABSTRACT:
An apparatus and a method for controlling an iris. The apparatus includes a data detector, a controller, and an iris controller using a feedback method, and further includes a buffer which stores an amplification ratio for modifying the input video signal to include a proper brightness level when the controller determines that adjustment of the iris is needed. An amplification ratio of 1 is stored when the controller determines that adjustment of the iris is not needed. A multiplier amplifies the input video signal by the amplification ratio stored in the buffer. As a result, a video signal having a proper brightness level is output.
