Abstract:
1. A method of controlling display content on an electronic display, the method comprising: receiving a control signal from a user interface, the user interface includes a rotatable dial that produces the control signal; receiving an electronic video input signal having a first pixel intensity associated with a first pixel; providing an electronic video output signal having a second pixel intensity for the first pixel, wherein the second pixel intensity is provided according to a plurality of zones related to the control signal, the zones each having a different zone relationship between the first pixel intensity and the second pixel intensity, wherein each zone is defined by a set of linear equations relating the first pixel intensity to the second pixel intensity, wherein each of the plurality of zones are associated with at least one predetermined degree range of dial rotation of the rotatable dial of the user interface, and the second pixel intensity is provided in accordance with a zone relationship of a selected zone of the zones, the zone relationship of the selected zone defining the second pixel intensity with respect to the first pixel intensity and a position of the user interface associated with the control signal; generating symbology at a graphics engine, the symbology generated in response to aircraft data; displaying an image associated with the video output signal on the electric display; and overlaying the symbology on the image such that the symbology is displayed at a symbology pixel intensity that is calculated independent of the second pixel intensity of the electronic video output signal, wherein the symbology pixel intensity is a maximum pixel intensity or a maximum apparent pixel intensity.
