Embodiment
Please refer to Fig. 1, Fig. 1 is the system block diagrams of hue regulation system of the present invention.Hue regulation system 100 includes a form and aspect decision-making circuit 110 and phase adjustment circuit of the same colour 120.At first selected certain color space, this color space can be RGB, YUV, YCrCb... or the like, and a color of object is represented with this kind color space.With color space YCrCb is example, this color of object through after parsing can obtain color format signal CF1_in, the CF2_in of at least two corresponding chromas (chrominance), for instance, wherein color format signal CF1_in is corresponding to the Cr composition of YCrCb, and color format signal CF2_in is corresponding to the Cb composition of YCrCb.This form and aspect decision-making circuit 110 promptly receives color format signal CF1_in, CF2_in that should color of object, and the form and aspect adjusted value of a plurality of corresponding different colours (promptly adjusting angle) Hue_A, Hue_B, Hue_C, Hue_D, Hue_E.Five form and aspect adjusted value Hue_A, Hue_B, Hue_C, Hue_D, Hue_E correspond to five different colors respectively, for example red, green, blue, yellow, Peg look, orange, purple ... etc. color in five, these form and aspect adjusted values all can be defined voluntarily by the user, that is at each color, the user can determine a form and aspect adjusted value.Be example with five form and aspect adjusted values among this embodiment, however should be with this as restriction of the present invention.Form and aspect decision-making circuit 110 produces one and marks form and aspect adjusted value (promptly adjusting angle) Hue_set mutually according to color format signal CF1_in, CF2_in and those form and aspect adjusted values Hue_A, Hue_B, Hue_C, Hue_D, Hue_E, these form and aspect are adjusted circuit 120 and are marked the form and aspect that form and aspect adjusted value Hue_set adjusts this color of object mutually according to this afterwards, that is the form and aspect angle of correction color format signal CF1_in, CF2_in, produce revised color format signal CF1_out, CF2_out subsequently.The thin portion mode of operation that this form and aspect decision-making circuit 110 and this form and aspect are adjusted circuit 120 describe in detail as after.
Form and aspect decision-making circuit 110 includes colour component parser circuitry 200, the form and aspect adjusted value is selected circuit 300 and linear interpolation circuit 400, and it is shown in Fig. 2 to Fig. 4 respectively.At first see also Fig. 2, colour component parser circuitry 200 receives this color format signal CF1_in and CF2_in, then this color format signal CF1_in, CF2_in is parsed a plurality of colour components (color tone).In practical operation, colour component parser circuitry 200 can be one tables look-up, and (more strictly speaking, colour component parser circuitry 200 is two-dimentional lookup table circuits for look-up table, LUT) circuit.Suppose that color format signal CF1_in and CF2_in all represent (for example 8bits) by a plurality of positions, then colour component parser circuitry 200 is with reference to several higher positions (MSB), the mode that utilization is tabled look-up resolves to four colour component signal Flag_1, Flag_2, Flag_3, Flag_4 with color format signal CF1_in, CF2_in.The form and aspect adjusted value is selected circuit 300 afterwards, as shown in Figure 3, according to each colour component signal Flag_n (in this embodiment, n equals 1,2,3 or 4) from choosing one among those form and aspect adjusted values Hue_A, Hue_B, Hue_C, Hue_D, the Hue_E, and the form and aspect adjusted value HFlag_n (in this embodiment, n equals 1,2,3 or 4) that output is corresponding.In practical operation, the form and aspect adjusted value selects circuit 300 to finish with a multiplexer, that is colour component signal Flag_1 can determine form and aspect adjusted value HFlag_1, a Flag_2 and determines that form and aspect adjusted value HFlag_2, Flag_3 determine form and aspect adjusted value HFlag_3 and Flag_4 determines form and aspect adjusted value HFlag_4.The linear interpolation circuit 400 afterwards, as shown in Figure 4, according to following equation, and utilize several lower positions (LSB) of color format signal CF1_in, CF2_in to come form and aspect adjusted value HFlag_1-HFlag_4 is carried out linear interpolation, to obtain target form and aspect adjusted value Hue_set.
Hue_set＝(A4×HFlag_1+A3×HFlag_2+
A2×HFlag_3+A1×HFlag_4)/(A1+A2+A3+A4)
Please consult Fig. 5 simultaneously, the position of target form and aspect adjusted value Hue_set is by several lower institute's interpolation decisions of color format signal CF1_in, CF2_in in the aforesaid equation, in the zone that A1-A4 is then surrounded for form and aspect adjusted value HFlag_1-HFlag_4, by each regional area that the position was partitioned into of form and aspect adjusted value Hue_set.This linear interpolation circuit 400 can be a bilinear interpolation circuit, or comes practical operation by two-stage single linear interpolating circuit.
Form and aspect among Fig. 1 are adjusted circuit 120 and are included form and aspect angle generation circuit 600 and form and aspect rotation circuit 700, are shown in Fig. 6 and Fig. 7 respectively.At first see also Fig. 6, the form and aspect angle produces circuit 600 and includes sinusoidal angle generation circuit 610 and cosine angle generation circuit 620.Target form and aspect adjusted value Hue_set produces after circuit 610 and 620 processing of cosine angle generation circuit through sinusoidal angle, converts form and aspect angle control signal sin θ and cos θ to.In the present embodiment, sinusoidal angle generation circuit 610 and cosine angle generation circuit 620 can come practical operation by lookup table circuit respectively.See also Fig. 7, form and aspect rotation circuit 700 produces the form and aspect that form and aspect angle control signal sin θ that circuit 600 produced and cos θ change color format signal CF1_in, CF2_in according to the form and aspect angle, just rotate the form and aspect angle of color format signal CF1_in, CF2_in, to obtain through color format signal CF1_out, CF2_out after the form and aspect adjustment according to following equation.
CF1_out＝CF1_in×cosθ+CF2_in×sinθ
CF2_out＝CF1_in×(-sinθ)+CF2_in×cosθ
In sum, the present invention resolves to a form and aspect color of object to be adjusted after some default colour component, find out the pairing form and aspect adjusted value of each colour component again, these form and aspect adjusted values can be by the user from ordering, and then those form and aspect adjusted values carried out the interpolation interpolation and find out target form and aspect adjusted value that should color of object.That is to say, can obtain a target form and aspect adjusted value for each color of object, the adjustment of form and aspect can give different adjusted values at different colors, has increased many elasticity, no longer all must do the form and aspect adjustment according to same adjusted value as all colours in the known technology.
The above only is the preferred embodiments of the present invention, and all equivalences of carrying out according to claim of the present invention change and revise, and all should belong to covering scope of the present invention.
