Patent ID: 8446373

Claim:
An electronic system comprising: a display configured to show an image; a proximity sensor adapted to detect objects in a sensing region; and a processing system coupled to the display and the proximity sensor, the processing system configured to: determine a reference measurement descriptive of a reference location of a first object relative to a reference location of a second object contemporaneously in the sensing region; determine a measurement descriptive of a location of the first object relative to a location of the second object contemporaneously in the sensing region; and apply a first rate of adjustment to a parameter of the image such that the parameter adjusts even if the first object is stationary relative to the second object in the sensing region and the second object is stationary relative to the first object in the sensing region, wherein the first rate of adjustment is variable based on the measurement and the reference measurement, and wherein the first rate of adjustment is zero if the measurement and the reference measurement are equal.
