Claim Text:
1. An image degradation prevention system for reducing image degradation, the image degradation prevention system comprising: a screen region monitor configured to cause at least one processor to derive light information for each of a plurality of regions of a display screen, the light information including light intensity information indicating a rate of change in light intensity of pixels within each region; an element movement detector configured to cause the at least one processor to derive element motion information for a plurality of display elements displayed in the plurality of regions, the element motion information indicating a rate of movement for each display element within the display screen; and a decision engine configured to cause the at least one processor to determine an impact of potential image degradation caused by each display element based on an evaluation of the light information and the element motion information, the decision engine configured to cause the at least one processor to select an at-risk display element as a candidate for causing image degradation based on the determined impact satisfying a threshold condition, the decision engine configured to cause the at least one processor to select a first corrective action for the at-risk display element, the decision engine configured to cause the at least one processor to select a second corrective action for the at-risk display element if the impact of potential image degradation has increased after the first corrective action has been applied, the second corrective action being different than the first corrective action.
