Abstract:

A display mode, including an update rate and/or resolution of an electronic display device, is dynamically adjusted by computing a change rate metric (CRM) representative of an image change rate, and adjusting, based on the CRM, at least one of the update rate and the image resolution. The display device may be switched between at least two display modes, based on the CRM, which may be computed by comparing each pixel row in a first frame with a corresponding pixel row in a comparison frame, and determining a number of pixel rows that have changed. A cyclic redundancy check (CRC) value for each pixel row may be computed, and the CRM may then be computed by determining a number of pixel rows that have a changed CRC value with respect to a corresponding pixel row of the comparison frame.
