Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the lamp effect control method according to the present invention.

While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein. Specifically, the lamp efficiency control method in this embodiment includes:

step S10, acquiring pixel information of a display picture associated with the light effect equipment;

in the embodiment, the light effect of the light is adjusted to the surrounding environment of the display device by combining the picture content displayed by the display device, so that the light effect can be used for supporting the display picture. Light effect devices are arranged around the display device. The display device may be a television screen, a computer display screen, or a projection screen, and the television screen is preferably used as an example for description herein. The lamp effect device may be an atmosphere lamp or a spot lamp, and the atmosphere lamp is preferably used as an example herein. The atmosphere lamps are arranged around the television screen, such as two sides, and are used for adjusting the light effects at two sides of the television according to the content displayed by the television screen, so that the light effects change along with the change of the displayed content.

Further, the ambience lamp and the television screen may be in direct communication connection, or both may be in communication connection with other control units, such as a projector or an intelligent network set-top box, i.e. a television box. If the television screen is in direct communication connection, the television screen directly controls the atmosphere lamp and changes the light effect by adjusting the displayed light color. If the intelligent network set top box is connected, the intelligent network set top box projects a screen to a television screen on one hand to realize video playing, and on the other hand, the intelligent network set top box controls the light color of the atmosphere lamp according to the played picture content to adjust the light effect.

The present embodiment preferably takes the case where the atmosphere lamp and the television screen are both in communication connection with the intelligent network set-top box. Specifically, the intelligent network set-top box may be wirelessly connected to the tv screen and the atmosphere lamp, such as a WiFi (Wireless Fidelity, Wireless network communication technology) and a bluetooth connection; or wired connection, such as HDMI (High Definition Multimedia Interface) and USB (Universal Serial Bus); the intelligent network set top box can be connected with the atmosphere lamp in a wireless mode, and the intelligent network set top box can be connected with the atmosphere lamp in a USB mode. No matter what connection mode, the intelligent network set top box can transmit data to a television screen through communication connection, and video playing is achieved. In addition, the played video may be a movie, a show, a general art, news, etc. on demand, or live news, a sports match, or a online game, etc., which is not limited.

Further, the intelligent network set top box monitors whether an atmosphere lamp starting instruction is received, and the starting instruction can be triggered by the connection state between the intelligent network set top box and the atmosphere lamp or other special triggering keys. If the connection state is used for triggering, when the atmosphere lamp is not required to be used, the intelligent network set top box is not connected with the atmosphere lamp, and once the connection state shows that the atmosphere lamp is required to be used, a starting instruction is triggered. If the intelligent network set top box is triggered by the trigger key, the intelligent network set top box and the atmosphere lamp can be always in a connected state, only the atmosphere lamp or a matched remote controller is provided with a key special for starting the atmosphere lamp, and a starting instruction is triggered by pressing the key.

Furthermore, if the intelligent network set top box monitors an atmosphere lamp starting instruction, screen capturing is carried out on a display picture related to the atmosphere lamp to obtain the display picture. The display picture is a content picture projected to a television screen by the intelligent network set top box and played, and a picture obtained by screen capture is the display picture. The screen capture can be realized through a screen capture command of an internal system of the intelligent network set top box, and for the intelligent network set top box of the android system, the screen capture can also be realized in a mode of reflecting android surface View.

In addition, because the played content has the characteristic of real-time change, the display color of the atmosphere lamp should be changed correspondingly. Therefore, the time interval for acquiring the display picture is preset, and the display picture is shot every time interval; and then the display color of the atmosphere lamp is controlled and changed according to the newly acquired display picture, so that the color of the atmosphere lamp changes along with the change of the color of the display picture.

Furthermore, an instruction or a function for acquiring pixel information of the display picture is arranged in the intelligent network set top box, after the display picture is acquired, the display picture is identified by calling the instruction or the function, and then the pixel information of the display picture can be acquired, wherein the pixel information is any one of a red-green-blue value, a red-green-blue-white value, a red-green-blue-green value, a red-green-blue-yellow value, a red-green-blue-powder value and the like of each pixel in the display picture. The present embodiment is preferably illustrated by taking as an example a red, green, blue value, namely a RGB (red, green, blue) tristimulus value, which comprises three components of an r (red) value, a g (green) value and a b (blue) value.

Step S20, averaging the pixel information to obtain a first color characteristic value;

further, by processing the pixel information, a first color feature value is obtained. The processing of the pixel information may be averaging processing or proportion processing. Namely, calculating the average value of RGB (red, green and blue) tristimulus values of each pixel in the pixel information, and taking the calculation result as a first color characteristic value; or calculating the proportion of the RBG tristimulus color values of each pixel, and taking the RGB value with the highest proportion as the first color characteristic value. The embodiment preferably obtains the first color feature value by means of averaging.

Step S30, when a preset enhancement condition is met, enhancing the first color characteristic value to obtain a second color characteristic value;

further, in order to ensure that the color display effect of the ambient light is more matched with the display picture, when the first color characteristic value meets a preset enhancement condition, the first color characteristic value is subjected to enhancement processing, and any one of an R value, a G value and a B value in the first color characteristic value, any two or three of the R value, the G value and the B value are subjected to numerical value change to enhance the first color characteristic value, so that a second color characteristic value is obtained. The preset enhancement condition is also set correspondingly according to the R value, the G value and the B value, and if the R value is set to be less than a certain value, enhancement is performed. Furthermore, it should be noted that the enhancement of the first color feature value is implemented by enhancing the overall display effect, and not only any one of the R value, the G value and the B value, but also any two or three of the R value, the G value and the B value are increased, and it is also possible that one of the R value and the G value is decreased, or one of the R value and the G value is increased and the other is decreased, so that the overall display effect of the second color feature value enhanced by the first color feature value is enhanced, thereby being beneficial to the viewing comfort of the user.

And step S40, generating a color change instruction according to the second color characteristic value to instruct the light effect equipment to display the light effect of the corresponding color.

And further, generating a color change instruction according to the enhanced second color characteristic value, and outputting the color change instruction to an atmosphere lamp serving as lamp effect equipment to control the change of the display color of the atmosphere lamp so that the atmosphere lamp displays the lamp effect of the corresponding color, so that the color of the atmosphere lamp changes along with the change of the color of the display picture, and the lamp effect of the atmosphere lamp is adjusted. For example, the ambience lamp displays a color corresponding to an RGB value of the first color feature value or the enhanced second color feature value according to the RGB value.

In this embodiment, pixel information of a display picture associated with a lamp effect device is obtained first, and the display picture is picture content that needs to display ambient atmosphere through lighting adjustment; averaging the obtained pixel information to obtain a first color characteristic value, and enhancing the first color characteristic value to obtain a second color characteristic value when the first color characteristic value meets a preset enhancement condition; and generating a color change instruction according to the second color characteristic value to indicate the light effect equipment to display the light effect of the corresponding color. Therefore, ambient light of the display picture changes along with the change of the display content, and the display picture is subjected to the baking by the ambient light; and, through color enhancement, make the lamp effect colour more bright-colored, be favorable to user's immersive to watch, promote to watch experience.

Further, referring to fig. 2, a second embodiment of the lamp effect control method of the present invention is provided based on the first embodiment of the lamp effect control method of the present invention.

The difference between the second embodiment of the lamp effect control method and the first embodiment of the lamp effect control method is that, when the preset enhancement condition is satisfied, the first color feature value is enhanced to obtain the second color feature value, and the method includes:

step S31, converting the first color feature value into a color element value, where the color element value includes a hue value, a saturation value, and a brightness value;

step S32, when the color element value satisfies the preset enhancement condition, enhancing the color element value;

step S33, converting the enhanced color element value into a color component value, and obtaining a second color feature value.

Further, HSV values are data that are more directly reflective of the color elements of interest to the user than RGB values. HSV (Hue, Saturation, Value) is a color model that contains three component values h, s, v. The h component represents the hue, and the value range is 0-360 degrees measured by the angle, the value is calculated from red in the counterclockwise direction, the red is 0 degree, the green is 120 degrees, and the blue is 240 degrees. Their complementary colors are: yellow is 60 °, cyan is 180 °, violet is 300 °. The S component represents the saturation, and the saturation S represents the degree to which the color approaches the spectral color. A color can be seen as the result of a mixture of a certain spectral color and white. The greater the proportion of spectral colors, the higher the degree of color approaching spectral colors and the higher the saturation of colors. High saturation and dark and bright color. The white light component of the spectral color is 0, and the saturation reaches the highest. Usually the value ranges from 0% to 100%, the larger the value, the more saturated the color. v represents brightness, brightness represents the degree of brightness of the color, and for the light source color, the brightness value is related to the brightness of the luminous body; for object colors, this value is related to the transmittance or reflectance of the object. Typically, values range from 0% (black) to 100% (white).

In this embodiment, the HSV value is used as the color element value, and the h component, the s component and the v component in the HSV value respectively form a hue value, a saturation value and a brightness value in the color element value. In order to better embody the color element value concerned by the user, in the process of enhancing the first color characteristic value, the first color characteristic value is firstly converted into the color element value, and the hue value H, the saturation value S and the brightness value V in the color element value are obtained for enhancement. Wherein the conversion can be achieved by, but is not limited to, the following equations (1) to (9).

R’＝R/255 (1)

G’＝G/255 (2)

B’＝B/255 (3)

Cmax＝max(R’，G’，B’) (4)

Cmin＝min(R’，G’，B’) (5)

Δ＝Cmax-Cmin (6)

v＝Cmax (9)

Understandably, the purpose of the enhancement processing of the first color characteristic value is to make the colors displayed by the atmosphere lamp more vivid and more highlight the atmosphere of the display picture. Therefore, if the color represented by the obtained first color characteristic value is bright enough to fully highlight the atmosphere of the display picture, the first color characteristic value does not need to be enhanced, otherwise, the first color characteristic value needs to be enhanced. Here, the preset enhancement condition is set in advance according to the color element value. After the first color feature value is converted into the color element value, the color element value is compared with the preset enhancement condition, whether the color element value meets the preset enhancement condition or not is judged, only when the color element value meets the preset enhancement condition, the fact that the first color feature value needs to be enhanced through enhancing the color element value is indicated, and otherwise, the fact that the first color feature value does not need to be enhanced.

Further, since the HSV value as the color element value includes three components, the preset enhancement condition may be set according to different components, thereby performing different judgments and enhancements. Specifically, when the color element value satisfies a preset enhancement condition, enhancing the color element value includes:

step S321, determining whether a saturation value in the color element values is smaller than a first preset value in the preset enhancement condition, and if the saturation value is smaller than the first preset value, increasing the saturation value;

further, a preset enhancement condition is set based on the saturation component s as a first preset value in the preset enhancement condition. And comparing the saturation value, namely the s value, in the converted color element value with a first preset value, and judging whether the saturation value is smaller than the first preset value. If the saturation value is less than the first preset value, the saturation value is low, and color deviation may occur when a user watches the color image, so that the saturation value in the color element value needs to be enhanced. At this time, it is determined that the color element value satisfies a preset enhancement condition, the saturation value is increased, and enhancement of the color element value is achieved by increasing the saturation value. The saturation value may be increased in a fixed value manner, or different first preset values are preset to correspond to different increased values, and the value is increased according to the first preset value corresponding to the saturation value, or may be increased in a proportional coefficient manner. For example, for the scaling factor increase mode, the first preset value and the preset increase multiple are values preset according to the requirement, such as setting the first preset value to be 0.8 or 0.9, and setting the preset increase multiple to be 1.5 times, 2 times, or 1.5 to 3 times, etc. Taking the first preset value of 0.9 and the preset increase multiple of 2 as an example, if the saturation value s in the color element values (h, s, v) is less than the first preset value of 0.9, the saturation value s is increased by 2, s ^ is obtained, and the enhancement of the color element values is realized.

It should be noted that, in addition to setting the preset enhancement condition according to the saturation component s, the preset enhancement condition may also be set according to the brightness component v. Specifically, when the color element value satisfies a preset enhancement condition, enhancing the color element value includes:

step S322, determining whether a brightness value in the color element value is greater than a second preset value in the preset enhancement condition, and if the brightness value is greater than the second preset value, decreasing the brightness value.

Further, a preset enhancement condition is set based on the brightness component v as a second preset value in the preset enhancement condition. And comparing the brightness value, namely the v value, in the converted color element value with a second preset value, and judging whether the brightness value is greater than the second preset value. If the brightness value is larger than the second preset value, the brightness value is higher, and the light effect color watched by the user is possibly too bright and whitened, so that the brightness value in the color element value needs to be processed. At this time, it is determined that the color element value satisfies a preset enhancement condition, the luminance value is reduced, and the enhancement of the color element value is realized by the reduction of the luminance value. The brightness value may be decreased in a fixed value manner, or different second preset values are preset to correspond to different decreased values, and the brightness value is decreased according to the second preset value corresponding to the brightness value, or may be decreased in a specific coefficient manner. For example, for the reduction of the specific coefficient, the second preset value and the preset reduction factor are values set in advance according to requirements, such as setting the second preset value to be a value between 70% and 90%, and the preset reduction factor to be 0.8 or 0.9, etc., that is, to be 0.8 or 0.9 of the original value, etc. Taking the second preset value of 80% and the reduction factor of 0.8 as an example, if the luminance value v in the color element values (h, s, v) exceeds the second preset value of 80%, v is reduced to 0.8 of the original value, and v ^ is obtained, thereby realizing the enhancement of the color element values.

Further, after the enhancement of the color element value is realized by increasing the saturation value or the enhancement of the color element value is realized by decreasing the brightness value, the enhanced color element value is converted into a color component value, i.e., an RGB tristimulus value, and a second color characteristic value is obtained, so as to facilitate the processing of the intelligent network set-top box.

It should be noted that, in addition to setting the preset enhancement condition separately according to the saturation component s and the brightness component v, the preset enhancement condition may be set in combination with both of them. At this time, when the saturation value in the color element value is smaller than a first preset value in a preset enhancement condition and the brightness value is larger than a second preset value in the preset enhancement condition, it is determined that the color element value meets the preset enhancement condition, and the saturation value and the brightness value are correspondingly adjusted, so that the enhancement of the color characteristic value is realized. Of course, a preset enhancement condition may also be set based on the hue component h, and the processing manner is similar to the saturation component s and the brightness component v, which is not described herein again.

This embodiment uses saturation component and/or brightness component to strengthen the colour eigenvalue as the basis, ensures that the atmosphere lamp shows that the colour is more bright-colored, and the user is immersed and is felt stronger in the time, has avoided appearing color deviation and/or lamp effect colour too bright, has promoted the experience that the user watched.

Further, referring to fig. 3, a third embodiment of the lamp efficiency control method of the present invention is provided based on the first or second embodiment of the lamp efficiency control method of the present invention.

The difference between the third embodiment of the light effect control method and the first or second embodiment of the light effect control method is that the averaging processing on the pixel information to obtain the first color feature value includes:

step S21, acquiring each color component of the selected pixel in the pixel information;

step S22, averaging the same color components of each selected pixel to obtain an average value of each color component;

step S23, determining a first color feature value according to the average value.

Further, a preset region indicating that pixel information processing is required is preset, for example, the preset region is set in a manner of a preset coordinate range, and two or more preset regions can be set through the preset coordinate range, for example, a display screen is divided into a left region and a right region, and the preset regions are respectively set for the left region and the right region. For the pixel information of the display picture, firstly, screening is carried out according to a preset area, pixels in the area of the display picture are selected, and each color component of the selected pixels is obtained, namely RGB tristimulus values are used as RGB tristimulus values of the color components.

Further, the same color components of each selected pixel are averaged to obtain an average value of each color component. Specifically, the same components in each RGB tristimulus value are summed, that is, all R values in each tristimulus value are summed, all G values are summed, and all B values are summed, to obtain a three-component summation result of the R value summation result, the G value summation result, and the B value summation result. And then, respectively comparing the sum result of the three components with the number of each pixel to obtain an R value ratio result, a G value ratio result and a B value ratio result, and forming an average value of each display component as a first color characteristic value. For example, if n pixels are selected, and the RGB tristimulus values of each pixel are (Rk, Gk, Bk) (k ═ 1, 2, 3 · · n), averaging is performed between the same components in the respective RGB tristimulus values, i.e., R ^ R1+ R2+ R3+ … … + Rn)/n; g ^ G (G1+ G2+ G3+ … … + Gn)/n; b ^ is (B1+ B2+ B3+ … … + Bn)/n, and the average value (R ^ G ^ B ^) of each color component is obtained as the first color feature value.

Understandably, the larger the number of pixels included in the display screen, the larger the amount of data that needs to be processed, thereby affecting the efficiency of the processing and slowing down the real-time control of the atmosphere lamp. Therefore, in order to improve the processing efficiency, when the pixels are selected from the target area of the display screen, the embodiment obtains relatively fewer color components for processing by reducing the number of the selected pixels. Specifically, the acquiring each color component of the selected pixel in the pixel information includes:

step S211, according to a preset calling rule, determining selected pixels in pixel information corresponding to a selected area, wherein the number of the selected pixels is smaller than the total number of the pixels corresponding to the selected area;

in step S212, the color component of each selected pixel is obtained.

Furthermore, a preset calling rule is set, a part of pixels are selected from a corresponding selected area of the display picture through the calling rule, and then color components of the selected part of pixels are obtained for processing, so that the processing efficiency is improved. The calling rule can be set according to the pixel rows, the pixel columns, the pixel rows and the pixel columns. Wherein, for the pixel row, at least one selected pixel is determined in every N pixels in the selected pixel row. That is, a certain line or several lines are selected from the pixels in the target area, and then the pixels to be processed are determined from the selected pixel lines according to the rule of the interval N. For a column of pixels, at least one selected pixel is determined every M pixels in the selected column of pixels. That is, a certain column or several columns are selected from the pixels in the target area, and then the pixels to be processed are determined from the selected pixel columns according to the rule of the interval M. Whether selected on a pixel row basis, a pixel column basis, or both, the number of selected pixels is less than the total number of pixels corresponding to the selected area, thereby reducing the number of pixels processed. N and M may be the same or different, and both values are natural numbers such as 1, 2, 3, and the like.

It should be noted that, the pixels reduced by the preset calling rule may be to extract a part of pixels as pixels to be processed in a pixel row or pixel column manner, or to remove a part of pixels and use the remaining pixels as pixels to be processed; instead of extracting or removing the pixels in the target area, the pixel position may be selected by the pixel row or the pixel column, and the pixel at the selected position may be used as the pixel to be processed. And, for the extraction and removal operation, it can be realized by the preset extraction rule and the preset removal rule. Specifically, the acquiring of each color component of the selected pixel in the pixel information includes:

a1, removing part of the selected pixels based on a preset removal rule, and obtaining each color component of the pixels left after removal; and/or

Step a2, extracting a part of the selected pixels based on a preset extraction rule, and obtaining each color component of the extracted part of the pixels.

Further, when a part of pixels are removed from the pixels in the target area to be used as unprocessed pixels or a part of pixels are selected from the pixels in the target area to be used as processed pixels, for the removal operation, a preset removal rule is preset, for example, one or more pixels are removed every N pixels, the rest pixels are used as pixels needing processing, and then the color components of the rest pixels are obtained to be processed. For the selection operation, a preset selection rule is preset, and for example, if M pixels at intervals are set, one or more pixels are extracted as pixels to be processed, and then each color component of the selected pixels is obtained for processing. Therefore, the selected pixels are reduced, the color components of the selected pixels are further reduced, the processing amount of the color components is reduced, and the processing efficiency is improved. N, M may be a positive integer value greater than 1.

Further, it is considered that a part of the display screen does not occupy the entire maximum display area, but a non-effective display area such as a black frame area or a white frame area may appear all around. The processing of the area is the processing of the invalid pixel, which reduces the processing efficiency, so the processing efficiency can be improved by determining the valid area from the display picture for processing. Specifically, the acquiring pixel information of a display screen associated with the light effect device includes:

step S11, acquiring a display picture;

step S12, determining a selected area in the display picture according to a preset selection rule, wherein at least one edge of two opposite sides of the selected area has a gap with the edge of the display picture;

in step S13, pixel information corresponding to the selected area is acquired.

In one embodiment of step S12, after all the pixel data of the display screen are obtained, the subsequent step S20 is not performed on the 0-Z1 rows of pixels closest to the upper edge and the 0-Z1 rows of pixels closest to the lower edge of the display screen; and/or, the subsequent processing of step S20 is not performed on the pixels in the 0-Z2 column closest to the left edge and the pixels in the 0-Z2 column closest to the right edge in the display screen, wherein the values of Z1 and Z2 can be set by a user or preset by a system. The left and right directions of the display picture are the long side directions of the picture, and the up and down directions are the short side directions. Specifically, in one embodiment, Z1 may be 10% of the total number of rows of pixels and Z2 may be 10% of the total number of columns of pixels. According to the scheme, the light effect is not influenced by the edge pixel data of the display picture, so that the situation that the effective display area in the display picture does not fully occupy the display range can be avoided, and the light effect can better aim at the effective area in the display picture.

Further, setting a preset selection rule, for example, setting a preset interception size, and carrying out image interception on the display image by taking the display center as a central point, wherein the interception size is the preset interception size, and the obtained display area is the selected area for removing the black frame or the white frame. Or setting the selection rule as a preset cutting size, cutting the display picture by taking the display boundary as a boundary, wherein the cutting size is the preset cutting size, and the display area obtained after cutting is the selection after removing the black frame or the white frame. No matter how the selected area is obtained, there is a gap between the edge of at least one opposite side of the circled area and the edge of the display frame, i.e. the size of the selected area is smaller than the size of the display frame. Thereafter, acquisition of pixel information is performed for the selected area to obtain a relatively reduced pixel information fast process.

On the other hand, when there are two or more light effect devices, each light effect device may form a one-to-one correspondence with a different selected area in the display screen, that is, the light effect of each light effect device depends only on the pixel information in the selected area corresponding to the light effect device.

In the embodiment, the effective display image area is selected, and the color components are obtained by selecting partial pixels to be processed, so that the number of pixels needing to be processed in the display image is reduced, the pixel processing efficiency is improved, a color change instruction can be generated rapidly, and the real-time and efficient control of the atmosphere lamp effect is realized.

Further, referring to fig. 4, a fourth embodiment of the lamp efficiency control method of the present invention is provided based on the first, second or third embodiments of the lamp efficiency control method of the present invention.

The fourth embodiment of the lamp effect control method differs from the first, second or third embodiment of the lamp effect control method in that it comprises:

step S50, when the preset enhancement condition is satisfied, generating a color change instruction according to the second color characteristic value, otherwise, generating a color change instruction according to the first color characteristic value;

step S60, generating the color change instruction at preset periodic intervals;

step S70, performing difference processing on the same color components appointed in the color characteristic values obtained in the previous period and the current period to obtain color component difference values;

in step S80, if the color component difference is smaller than the third preset value, the color change instruction in the current period is stopped being generated, or the color change instruction is generated as same as the color change instruction in the previous period.

In this embodiment, if the first color characteristic value does not satisfy the preset enhancement condition and does not need enhancement, a color change instruction is directly generated according to the first color characteristic value; and otherwise, if the first color characteristic value meets the preset enhancement condition and needs to be enhanced and the second color characteristic value is obtained through enhancement, generating a color change instruction according to the second color characteristic value. And preset period intervals are preset, and color change instructions are generated every interval in the period.

Understandably, the content of the television screen projected and played through the intelligent network set top box has the characteristic of dynamic change, and the content played at different moments is different, so that the problem that the lamp effect change cannot keep up with the displayed picture can be caused if the lamp effect of the atmosphere lamp changes slowly, and the problem that the watching effect is influenced by frequent screen flickering can be caused if the lamp effect of the atmosphere lamp changes quickly. For this reason, the present embodiment sets the preset periodic interval to a suitable time, such as 0.01 second, 0.1 second, 0.5 second, etc., by a test. And synchronously acquiring the playing content at each interval of the period to obtain a display picture, thereby realizing the periodic acquisition of the pixel information of the display picture. And a contrast mechanism of two continuous periods is set, if the pixel information of the display pictures in the two continuous periods is not greatly changed by contrast, the control of the lamp effect change of the atmosphere lamp is not carried out, so that the influence of frequent flicker of the color of the atmosphere lamp on the watching of the user is avoided.

Specifically, after the pixel information of the display frame is obtained in the current period and the color characteristic value (the first color characteristic value or the second color characteristic value used for generating the color change instruction) is obtained, the color characteristic value (the first color characteristic value or the second color characteristic value) obtained according to the pixel information of the display frame in the previous period is read from the storage unit of the intelligent network set top box. And performing difference processing on the same color components appointed in the color characteristic values obtained in the previous period and the current period, performing difference operation between the component R values of the color characteristic values and the component R values of the color characteristic values, performing difference operation between the component G values, and performing difference operation between the component B values to obtain an operation result, and performing absolute value operation on the operation result to obtain a color component difference value with a positive numerical value. The color characteristic value is a first color characteristic value or a second color characteristic value used for generating a color change command. Wherein the same color component specified is, for example, an R value in the color feature value in the previous cycle and an R value in the color feature value in the current cycle; and the color component can be selected by the user or preset by the system, and the color component is not limited to the conventional R component, G component or B component, and for some devices whose display screen involves four-color display, the color component may also include one of the unconventional color components such as white component, pink component, yellow component, etc.

Further, in order to represent the change size of the pixel information of the display pictures in two consecutive periods, a third preset value is preset, the obtained color component difference value is compared with the third preset value, and whether the color component difference value is smaller than the third preset value is judged. The third preset value may be any integer value from 15 to 30. If the current period display content is less than the previous period display content, the current period display content is not greatly changed relative to the previous period display content, and the lamp effect of the atmosphere lamp is judged not to be adjusted, so that the color change instruction of the current period is stopped to be generated, or the same color change instruction as the previous period is generated, so that the atmosphere lamp is still displayed in the previous display color. If the compared color component difference value is greater than or equal to the third preset value, it indicates that the display content in the current period has a larger change relative to the display content in the previous period, and the lamp effect of the atmosphere lamp needs to be adjusted. Therefore, a new color change instruction is generated according to the color characteristic value of the current period and is output to the atmosphere lamp so as to regulate and control the display lamp effect of the atmosphere lamp. And, the color characteristic value of the current period is saved for comparison of the next period.

Further, since the difference processing of the same color component in the color feature value includes processing of a component R value, a component G value, and a component B value, in order to accurately reflect the color change of the screenshot picture in two consecutive periods, the difference generated by each of the three components should be compared with a third preset value. With the above, the difference results obtained by the difference processing on the component R value, the component G value, and the component B value, respectively, are taken as the red component difference, the green component difference, and the blue component difference included in the color component difference. If the color component difference is smaller than a third preset value, stopping generating a new color change instruction, or generating a color change instruction the same as that of a previous cycle, including:

step S81, if the red component difference value, the green component difference value, and the blue component difference value are both smaller than a third preset value, the generation of the color change instruction in the current period is stopped, or the color change instruction identical to the color change instruction in the previous period is generated.

Furthermore, the color feature value of the current period includes a component R value, a component G value and a component B value, and the enhanced color feature value of the previous period also includes a component R value, a component G value and a component B value. Difference operation and absolute value operation are respectively carried out among the component R values, among the component G values and among the component G values, a red component difference value, a green component difference value and a blue component difference value are obtained, and the red component difference value, the green component difference value and the blue component difference value are formed into color component difference values.

And further, comparing the red component difference value, the green component difference value and the blue component difference value with a third preset value respectively, and judging whether the red component difference value, the green component difference value and the blue component difference value are all smaller than the third preset value. And if the color component difference values are smaller than the third preset value, judging that the color component difference values are smaller than the third preset value, and at the moment, the display content in the current period is not greatly changed relative to the display content in the previous period, so that the lamp effect of the atmosphere lamp does not need to be adjusted, and the generation of the color change instruction in the current period is stopped, or the color change instruction which is the same as that in the previous period is generated. On the contrary, if the red component difference value is determined through comparison, and any one of the green component difference value and the blue component difference value is larger than or equal to the third preset value, it indicates that the display content in the current period has larger change relative to the display content in the previous period, and the light effect of the atmosphere lamp needs to be adjusted. At the moment, the color component difference value is judged to be larger than or equal to a third preset value, and a color change instruction is generated according to the color characteristic value of the current period to adjust the display lamp effect of the atmosphere lamp.

This embodiment just adjusts the display lamp effect of atmosphere lamp when the contrast shows that the display color changes greatly through the color characteristic value contrast in two consecutive periods around, shows that the color change is not big then not adjusting the display lamp effect of atmosphere lamp, avoids showing the excessive regulation that the lamp effect was shown to the atmosphere lamp and makes atmosphere lamp frequent scintillation, is favorable to user's viewing effect when guaranteeing the atmosphere.
