ABSTRACT:
The invention provides a method for software contrast control and a portable computer implementing software contrast control. The contrast control is initiated by a single interaction with an input mechanism, for example a pressing of a dedicated contrast control button. The method can be applied more generally to viewing parameters other than contrast such as brightness, color bit depth, color versus monochrome, and screen resolution. The method includes a processor disposed in the portable computer receiving an activation signal from a button or other input mechanism, and displaying viewing parameter adjustment graphics on the image screen. The method continues with the processor receiving a viewing parameter adjustment signal and responding to the adjustment signal by adjusting the viewing parameter levels for the image screen to levels based on the adjustment graphics. The method can include activating the input mechanism by applying a single interaction to thereto prior to the receiving of the activation signal for viewing parameter control. The portable computer can include a display, a contrast control hardware button, a processor, and a memory. The viewing parameter levels vary in response to image screen drive voltages. The processor responds to input applied to the viewing parameter control graphical user interface elements by adjusting the viewing parameters. The applying of the input includes one or more of selecting and adjusting one or more of the viewing parameter control graphical user interface elements.
