摘要： An image control method and apparatus for a digital monitor that is capable of controlling a contrast and a color temperature in the digital monitor is disclosed. In the method, an offset control signal is produced. A digital input signal is added to the offset control signal. An added value of the digital input signal and the offset control signal is limited within a desired reference value. Accordingly, a contrast and a color temperature of the digital input signal can be controlled in the digital monitor.
