Embodiment
The present invention discloses a kind of method of improving the rainbow phenomena phenomenon in look preface method color shows.According to (random) color order, standard at random (quasi-random) color order or predetermined (predetermined) pattern (pattern) that color order proposed at random, can improve the rainbow phenomena phenomenon that in look preface method color shows, occurs significantly.
In one embodiment, in the look preface method color that disclosed showed, being used for time was the preface show image, and the pattern of proposition can show in color order mode at random; In another embodiment, in the look preface method color that disclosed showed, being used for time was the preface show image, the pattern of proposition can with standard at random the color order mode show; Again in another embodiment, in the look preface method color that is disclosed showed, being used for time was the preface show image, and the pattern of proposition can show with the pre-color sequential system.
In the look preface method color that is disclosed showed, each picture or field can temporarily be divided into the subframe of at least three kinds of solid colors.Just can experience a width of cloth full color image by showing these red, green and blue look subframes in order fast enough.In the look preface method color that disclosed showed, many being used for time was that the color order of preface show image is by pre-configured, to solve the problem of rainbow phenomena.
In the look preface method color that is disclosed showed, the color DISPLAY ORDER of first picture can be different with the color DISPLAY ORDER of second picture.Each picture can comprise three kinds of color subframes, for example, and the subframe of three primary colors (primary color), promptly red subframe, green subframe and blue subframe.
In one embodiment, in the look preface method color that disclosed showed, being used for time was that the color order of preface show image can be a color order at random.For example, be used for time be the preface display image information color order can be " RGB GRB BGR RBG ... " it can be arbitrarily in proper order, and is not restricted to fixing, unmodifiable order.That is be still red, green and blue look subframe (R, G and B) combine constitute a picture or, still, each picture that is used to manifest look preface method color mode or among, red, green and blue look subframe (R, G and B) can dispose in any order.
In another embodiment, in the look preface method color that disclosed showed, being used for time was that the color order of preface show image can be a standard color order at random.That is be still red, green and blue look subframe (R, G and B) combine constitute a picture or, but, the part picture that is used to manifest look preface method color mode or among, red, green and blue look subframe (R, G and B) can dispose in any order, and among another part picture or field, red, green and blue look subframe (R, G and B) is by the pre-color arranged in order, and wherein pre-color depends on predetermined design in proper order.
According to various embodiment, comprise at random or the look preface method color of accurate color order at random shows and can comprise random digit generator (random number generator) that wherein the random digit generator can distribute at random or standard color order at random.Can be used as known various random digit generators in the known techniques.Yet, can expect also to can be used for distributing at random or standard color order at random as known other technologies in the known techniques.
