Abstract
The invention corrects display faults due to the disparities between the phosphors of a display device. The correction is carried out by image processing. The invention provides a method for displaying a sequence of video images on a phosphor device comprising at least two types of phosphors together with the device comprising the means for implementing this method. The correction is carried out by computing an intermediate image between two successive images, then by displaying one of the two successive images on one type of phosphor and by simultaneously displaying the intermediate image on another type of phosphor.

Method for displaying a sequence of video images on a phosphor device comprising at least two types of phosphors (blue, green, red), characterized in that at least one intermediate image between two successive images (image I, image I-1) is computed, then one of the two successive images (Image I) is displayed on at least one type of phosphor (green) and the intermediate image is displayed simultaneously on at least one other type of phosphor (blue, red).
Device for displaying a video sequence comprising at least two types of phosphor, characterized in that it comprises means (12, 13) for computing at least one intermediate image placed between two successive images and means (14 to 19) for displaying the intermediate image on one of the types of phosphor and one of the successive images on the other type of phosphor.
