Static design sketch is divided into n block along abscissa bearing of trend, and the ratio between each block is consistent with the ratio that time shaft is divided;
Color and luminance component according to light source in each time period, color and the brightness of drawing the corresponding block of static design sketch.
Conventionally light source can, according to default rule circulation change, for avoiding repeating to draw, can only be drawn the variation effect of one-period.For the light source of acyclic variation, using complete variation as one-period, i.e. the light source of acyclic variation thinks to only have one-period.The duration of supposing one-period is T, according to the variation of the color of default light source and brightness, one-period is divided into n time period, the duration of each time period be respectively T1, T2, T3 ..., Tn, T1+T2+T3+ ... + Tn=T.A corresponding light source component of each, whole T is just corresponding one-period inner light source is at color and the luminance component variation characteristic of each time period time period.Various colors all can obtain by the combination of RGB three primary light source, therefore, only need the situation of change of default RGB three-color light source.N at one-period T changed in the period, and three primary light source component and the corresponding relation between the time period can adopt following characteristics function representation:
The duration T1:Fr1(t of the 1st time period), Fg1(t), Fb1(t);
The duration T2:Fr2(t of the 2nd time period), Fg2(t), Fb2(t);
……
The duration Ti:Fri(t of i time period), Fgi(t), Fbi(t);
……
The duration Tn:Frn(t of n time period), Fgn(t), Fbn(t).
Wherein, Fri(t) represent the component characteristic function of i period red light source, Fgi(t) represent the component characteristic function of i period green light source, Fbi(t) represent the component characteristic function of i period blue-light source.
The realization of static design sketch need to be described the change color of sequential out on static images.The present embodiment be take static design sketch cross directional variations as example description, and longitudinal situation of change of static design sketch can be analogized.The abscissa total length of supposing static design sketch is S, according to time shaft division proportion, by the abscissa of static design sketch be divided into n block S1, S2, S3 ..., Sn, S1+S2+S3+ ... + Sn=S, corresponded to n block of static design sketch the n of a light source dynamic change time period, the abscissa length Si=(Ti * S of i block in static design sketch)/T.
According to above-mentioned three primary light source component and the corresponding relation between the time period, and the corresponding relation of time period and static design sketch abscissa length, can obtain the corresponding relation between three primary colors color component and static design sketch abscissa length, adopt following characteristics function representation:
The 1st block length S1:Fr1(s), Fg1(s), Fb1(s);
The 2nd block length S2:Fr2(s), Fg2(s), Fb2(s);
……
I block length Si:Fri(s), Fgi(s), Fbi(s);
……
N block length Sn:Frn(s), Fgn(s), Fbn(s).
Wherein, Fri represents i block red component characteristic function, and Fgi represents i block green component characteristic function, and Fbi represents i block blue component characteristic function.
By above-mentioned function, change, can draw out strictly accurate, clear understandable static design sketch, reflect light source dynamic change effect.The red light source that the one-period of take is 10 seconds is example, the situation of change of red light source is from extinguishing state linearity, to increase red brightness in first 5 seconds, during by the 5th second, red brightness is maximum, within latter 5 seconds, reduce gradually red brightness, during by the 10th second, redness is extinguished, can be in the lump with reference to Fig. 8, static design sketch is divided into 10 blocks on abscissa, it within every 1 second, is a block, the color of two ends, left and right block is the darkest, for black, the color of middle block is the brightest, for shiny red, from two ends block to middle block, there is the process of a gradual change, user is according to static design sketch, can find out intuitively the effect of light source dynamic change accurately, be convenient to fast, select accurately the control mode of expectation to control light source variation.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
