The three primary color digital signals are respectively output to the display with individual grayscale values, so that the pixels of the flat display display corresponding colors.

However, the color system of RGB space does not conform to the habit of color description by ordinary people. In fact, the color system that is closer to the human eye is HSV • Space, that is, Hue, H, Saturation, S, and Lightness. Representation of (Value, V). Therefore, the current technology converts the input signals representing the three primary colors of RGB to the corresponding HSV space for processing. For example, after the enhanced S value is converted, the input signal is converted back to the color space represented by the three primary colors of RGB. However, the conversion relationship between RGB space and HSV space developed according to the definition of chromatics is a nonlinear transformation. Therefore, the hardware that performs the conversion function will inevitably cause a certain amount of burden, so that the signal is 5 1356640, %.

TW3279PA - In order to make the above-mentioned contents of the present invention more comprehensible, the following description of the preferred embodiments and the accompanying drawings will be described in detail as follows: [Embodiment] For the first embodiment, please refer to FIG. A block diagram of an image color adjustment device according to a first embodiment of the present invention. The image color adjustment device 1 is used to adjust the color of the input image data. The image data herein includes red (R, G) image data, green (Green) image data, and blue (Blue) image data, which are represented by (R^G^Bi) in this embodiment. The image coloring device 100 includes a difference amount generating module 110, a correction module 120, and an adjusting module 130. The difference amount generation module 110 is configured to calculate a set of image data difference amounts according to the input image data (R^G^Bi), which is represented by (ΔR, AG, Z\B) in this embodiment. Preferably, the difference amount generation module 110 includes a classification unit 111, an adjustment parameter generation unit 112, and a calculation unit 113. The adjustment parameter generating unit 112 is configured to store a plurality of sets of adjustment parameters, and each set of adjustment parameter pairs should have an index value (index). Among them, each index value represents a different color area. The classifying unit 111 records the classification conditions of the image data to classify the image data, and outputs at least one index value corresponding to the image data. For example, the classification condition of the image data is generated by dividing the input image data into different regions according to the hue. Assume that the range of the defined hue is (0, 1), according to the definition of RGB space conversion to HSV space, when the range of hue is (〇, 1/6), it is defined as classification area 1, and the derived classification condition is R> G and G>B; defined as 7 13.56640 ft when the hue range is (1/6, 2/6)

' TW3279PA 4 classification area 2, the classification condition is G>R and R>B; when the range of hue is (2 / 6,3 / 6), it is defined as classification area 3, and the classification condition is 0>8 and already>ruler; when the range of hue is (3/6, 4/6), it is defined as classification area 4, and the classification condition is B>G and G>R; when the range of hue is (4/6, 5/6) is defined as the classification area 5, and the derived classification condition is B>R and R>G; when the range of the hue is (5/6, 1), it is defined as the classification area 6, The classification condition is R>B and B>G; when the range of hue is (0, 1/12), it is defined as classification area 7, and the classification condition is R>(2xG-B) and G>B. That is to say, as long as the range in which the hue value is located is determined, the classification condition of the corresponding image data can be derived. In the above classification manner, the index values corresponding to the classification area 1 to the classification area 7 can be defined to be 1-7, respectively. As long as the input image data meets the classification condition of a certain classification area, the classification unit 111 outputs an index value corresponding to the classification area. It should be noted that the above classification method may have a partial hue range of two depending on the situation. The above index values, for example, when the hue range is (0, 1/12), there will be two index values of 1 and 7. • When the index value corresponding to the image data is found, the classification unit 111 transmits the index value to the adjustment parameter generation unit 112. The adjustment parameter generation unit 112 stores a plurality of sets of adjustment parameters, and outputs a set of adjustment parameters corresponding to the index values according to the index values output by the classification unit 111. In this embodiment, the adjustment parameters include a chroma adjustment parameter, a brightness adjustment parameter, and a hue adjustment parameter, and are represented by a matrix of 3x3, respectively. Actually, in application, the values of the three matrices may be correspondingly summed and stored in the database 111 to reduce the amount of calculation of the matrix. The calculating unit 113 is configured to be based on the corresponding index value. 8 13.56640 4 f

The corresponding adjustment parameter matrix

In addition, the image data may also correspond to multiple index values at the same time. For example, if the hue of the image signal is in the range of (0, 1/12), it corresponds to the index values 1 and 7. The index values 1 and 7 respectively correspond to a set of adjustment parameters, and the adjustment parameter generation unit 112 generates and outputs two sets of adjustment parameters according to the index value 1 and the index value 7. In this embodiment, the adjustment parameter matrices corresponding to different index values are correspondingly added to generate a comprehensive adjustment parameter. The calculation unit 113 performs matrix calculation based on the comprehensive adjustment parameters and the image data, and calculates the amount of difference in the image data. If the hue range of the image signal corresponds to only one index value, the calculating unit 113 performs matrix calculation according to the parameter corresponding to the index value and the image data, and calculates the image data difference amount. The correction module 120 is configured to generate at least one adjustment weight according to at least one of a hue value, a chroma value and a brightness value corresponding to the image data, and correct the image data difference amount according to the adjustment weight. The purpose of correcting the amount of difference in image data is to express the fineness of the image and to solve the problem of discontinuity between different classification areas after image adjustment. For example, the image parameters classified in the same classification area correspond to the same set of adjustment parameters, so the calculation unit 113 calculates the image parameter difference amount according to the same adjustment parameter, in order to adjust differently for individual image data in the same classification area. , Ben 9 13.56640

The TW3279PA embodiment produces corresponding adjustment weights for at least one of hue, chroma, and lightness of individual image data. In addition, the weight adjustment method only needs to store the maximum value of the image data difference in each adjustment area, and then adjust according to the adjustment weight corresponding to the image data, thereby saving the use of the memory during the color calculation. The correction module 120 includes a conversion unit 121 and a first weight generation unit 122. The converting unit 121 is configured to convert at least one of a corresponding hue value, a chroma value, and a brightness value according to the image data, where the first weight generating unit 122 is configured to generate at least the hue value, the chroma value, and the brightness value generated by the converting unit 121. One of the at least one adjustment weight is generated, and the image data difference amount is corrected according to the adjustment weight. In this embodiment, the first weight generating unit 122 includes a color look up table 122a and a multiplier 122b. Therefore, the first weight generating unit 122 detects the corresponding hue adjustment weight WH in the hue weight check table 122a based on the hue value of the image data, and the multiplier 122b corrects the image data difference amount based on the hue adjustment weight WH. Therefore, in the present embodiment, the corrected image data difference amount (ΔR, AGr, ΔΒ') can be calculated using the formula (2).

As shown in Figure IB, assuming that the adjusted hue region is defined between Ha and Hb, the hue angle in the adjusted region is a fixed value, for example, increasing the hue angle of all regions in the region by 5 degrees, as shown by curve 11. Show. As a result, since the hue value outside the adjustment area does not change, the hue value will be discontinuous at two points of H and Hb. Please refer to FIG. 1C, which is a schematic diagram of adjusting the hue angle of the image data according to the embodiment of the present invention after performing weight adjustment. As shown in Fig. 1C, after the weight adjustment, since the weights at the private and Hb points are set to 0, the hue value is not adjusted at these two points, so that the hue change of the entire image is continuous. In the range of Ha and Hb, the weight adjustment is performed according to different hue values, so that the image shows more details on the color change. The weight can be adjusted nonlinearly as shown in curve 12; it can also be segmentally linearly adjusted as curve 13, and the left and right are asymmetrical changes; or as curve 14 is nonlinearly adjusted, and the left and right are asymmetrical. But all hue weights are greater than or equal to zero. The adjustment module 130 is configured to adjust the image data (R^Gi, :^) according to the corrected image data difference amount (ΔR', AG', ΔΒ'). In this embodiment, the adjustment module 130 is an adder, and the image data difference amount (ΔΙΙ', Z\G', ΔΒ') is compared with the image data (R^GbBi) as shown in the formula (3).

Referring to FIG. 2, a flow chart of an image color adjustment method according to a first embodiment of the present invention is shown, and the component number of FIG. 1A is also referred to. First, as shown in step 201, based on the input image data (R^GJi), the difference amount generation module 110 generates a set of image data difference amounts (ΔR, Z\G, AB). Among them, the image data (R^G^Bi) includes red image data Ri, blue image data 〇彳 and green image data Bi. The step 201 is further subdivided into the following steps: First, the image data is classified by the classifying unit 111 to output an index value (index) of the corresponding image data (R^G^Bi) to the adjustment parameter generating unit 112, and the index The value corresponds to a set of adjustment parameters. Next, the calculation unit 113 calculates the image data difference amount (/\11, /\0, /\; 6) according to the adjustment parameter and the image data (1^丨, ;^). When the image data corresponds to multiple index values, step 201 can be further subdivided into the following steps: First, the classification unit 111 classifies the image data (RbG^Bi) to output the image data (I^Gi, :^) correspondingly. Index values, each index value corresponds to a set of adjustment parameters. Next, the adjustment parameter generation unit 112 generates a set of comprehensive adjustment parameters according to the adjustment parameters corresponding to the respective index values. Then, the calculation unit 113 calculates the image data difference amount (ΔΙΙ, ΔΟ, ΔΒ) based on the comprehensive adjustment parameter and the image data (I^G^Bi). Next, as shown in step 202, the correction module 120 generates at least one adjustment weight according to at least one of a hue value, a chroma value, and a brightness value corresponding to the image data (R^G^Bi). In the present embodiment, the correction module 120 generates an adjustment weight WH based on the hue value. The step 202 is further subdivided into the following steps: First, the converting unit 121 calculates the corresponding image data 12 1356640

Then, as shown in step 203, the correction module 120 corrects the image data difference amount according to the adjustment weight (^!1, ^(}, eight. In this embodiment, the first weight generation unit in the correction module 120 is used.

Therefore, the second weight generating unit 123 is based on the chroma value of the image data. After the chroma weight check table 123a finds the corresponding chroma adjustment weight Ws, the multiplier 123b corrects the image data difference amount (ΔΙΙ', ΔG', ΔΒ') based on the chroma adjustment weight Ws. Therefore, in the present embodiment, the corrected image data difference amount (AR, ', AG' ', ΔΒ',) can be calculated using the formula (4).

The chroma is a schematic diagram before weight adjustment. For example, if you want to adjust the chroma of the image data, as shown in Figure 3B, the range of the chroma value is (〇, 1), and it is assumed that the color of the image parameter is adjusted by the amount of image parameter difference without weight adjustment. The result of the degree is a chroma increase of 0.5, as shown by curve 21. As a result, the original area with a chroma of more than 0.5 will be saturated, which will make the image color lose its layering. In addition, if the area with no chroma (chroma is 〇) is directly increased by 0.5, the original colorless area will be colored. Please refer to FIG. 3C, which is a schematic diagram of adjusting the chroma of the image data after performing weight adjustment according to the second embodiment of the present invention. As shown in Figure 3 C, after the chroma weight adjustment is performed, since the weight is set to 0 when the chroma is set and the weight is 1 when the chroma 1 is set, the chroma value will not be adjusted at these two points. It does not image the original colorless and saturated areas, and makes the color appear more layers.

The range is (0, 1), and it is assumed that the image parameter difference is adjusted without weight adjustment. The result of the chroma of the parameter is a brightness increase of 0.5, as shown by curve 31. Thus, the original brightness is greater than 0.5. The area will be saturated, making the image Loss of the layering of the brightness change. In addition, the original black (lightness is 〇), region, if directly increased 〇·5, the original black area will have = degree three Ming with reference to Figure 4C, which illustrates an embodiment in accordance with the present invention.
