FIELD: physics, video.
SUBSTANCE: invention relates to image display. Image display comprises inserting black elements for two types of video frames relating to images for the left eye and the right eye or to mutually different images. The method employs a unit (16) for successively outputting video signals for the left eye and the right eye, a unit (19) for storing a mask pattern, a counter (18) for selecting a mask pattern and a mask synthesis unit (17). The unit (16) successively outputs two types of video frames. The unit (19) stores m mask patterns, where main regions are defined in the pixel region of a liquid crystal panel, wherein the pixel region contains m pixels in the form of a matrix, and m is an even number equal to or greater than 4, m mask patterns have different mask pixel configurations in the main region, and the number of mask pixels is equal to an even number less than m and equal or greater than 2. The counter (18) successively selects each of the mask patterns. The unit (17) synthesizes the selected mask pattern on the output video frame. Each of the pixels in the main region is replaced with a mask pixel the same number of times in m mask patterns.
EFFECT: reducing the level of after-images perceived by a user.
