SYSTEMS AND METHODS FOR CONTROLLING A DISPLAY SCREEN OF A PORTABLE COMPUTING DEVICE

摘要

A system and method for controlling how images are displayed on a display screen of a portable computing device changes the orientation of the images on the display screen when the orientation of the portable computing device changes. If the orientation of the portable computing device is changing only infrequently, the orientation of the images on the display screen may be rapidly changed when the orientation of the portable computing device changes. If the orientation of the portable computing device is changing relatively frequently, the orientation of the images may not switch until after a delay period has expired after each change in orientation of the portable computing device occurs.

1. A method of controlling the orientation of images on a display screen of a portable computing device that is configured to display images in different orientations on the display screen when the portable computing device is positioned in corresponding different orientations, comprising:
determining a duration of a switching time period that elapses between a first point in time at which the portable computing device changes from a first orientation to a second orientation, and a second point in time at which the portable computing device switches from the second orientation back to the first orientation or to another orientation; and causing an image displayed on the display screen of the portable computing device to switch orientations on the display screen only after a delay time period has elapsed after the orientation of the portable computing device has changed, wherein the delay time period is a first delay time period if the switching time period is greater than or equal to a threshold duration, and wherein the delay time period is a second delay time period that is longer than the first delay time period if the switching time period is less than the threshold duration.
