Among the present invention; If when the dominant hue of main image is purple, we can be designed to subpictures the two frame subpictures of the blue word in the red end and The Scarlet Letter of the blue end, and the literal size is identical with the position separately; This two frames subpictures is purple altogether; Do not influence most of spectators to the watching of main image, if but we open light valve when only 1 frame subpictures shows therein, and we can only see the subpictures of the blue word in the red end or The Scarlet Letter of the blue end.
For another example; When main image is grey screen; We can be designed to a frame be the white background black arrow with another frame is the identical but subpictures of black white reverse of the two frame displaying contents formed of black matrix white arrow subpictures, and this two frames subpictures is grey screen altogether, does not influence most of spectators watching main image; If when being which frame subpictures but we only watch wherein with light valve, what we saw all is the image of an arrow.
In order to improve the viewing effect of main image and subpictures; Best bet is separately to play main image and subpictures at the diverse location of screen; Be used for playing main image to 2/3 zone of screen such as us, other 1/3 zone is used for playing subpictures, and we are when playing main image like this; Main image is play in 2/3 zone, and 1/3 zone can be made as grey.And when playing subpictures; The image the same with main image still play in 2/3 zone; It is white gravoply, with black engraved characters and another frame is the identical but subpictures of black white reverse of the two frame literal formed of black matrix wrongly written or mispronounced character that 1/3 zone is play by a frame, and this two frames subpictures is grey screen altogether, like this we with the naked eye see regardless of being that main image or subpictures all are identical; When being which frame subpictures but we watch wherein with light valve, what we saw all is the picture of a band literal.Said method can be used for the captions of movie or TV; Be placed on the captions of different language in the different subpictures; We can regulate the switching time of light valve arbitrarily and select our needed captions, do not influence other people normal viewing movie or television fully.
It should be noted that in the above-mentioned resultant image that the ratio of the subpictures of insertion is more little for main image, the frame frequency that needs is just high more.It is a kind of to suppose that the subpictures that inserts has only, and both ratios are 2: 2, and then the frame frequency of resultant image is more preferably greater than 240Hz, and whole display frame just is unlikely to flicker.If 1: 2, then the frame frequency of resultant image is more preferably greater than 180Hz.Both the ratio when main image and insertion subpictures was A: during B, the frame frequency of resultant image could keep picture not glimmer more than being preferably in (A+B) X60Hz.In order to make subpictures not influence the display quality of main image fully, hope that the frame frequency of resultant image is high more good more.
In addition, because above-mentioned resultant image need accurately control to each frame, thus require to implement the computer monitor of usefulness, television set, cinematographic projector, the scan mode of large photoelectric display screen etc. can cooperate this mode.The single frames progressive scan mode is more suitable.And the composograph of subpictures is consistent with the background color of master image if desired, just requires enough fast of the response speed of display, otherwise need be according to the mutual tone of the difference fine setting of image to keep coupling.
