s1, dividing the user picture into a plurality of color extraction areas, and establishing a binding relationship between each peripheral device and each color extraction area, wherein the number of the peripheral devices is the same as that of the color extraction areas.
Since the number of the peripheral devices interacting with the display device at the same time can be multiple, and the display device of each peripheral device only changes along with the color of the corresponding position of the user picture, the user picture can be divided into a plurality of color extraction areas for accurately determining the color of the corresponding position of the user picture which can be presented by each peripheral device, and the color extraction areas are used for providing the color presented by the corresponding position of the user picture.
In dividing the regions, in some embodiments, the controller, in performing dividing the user screen into a plurality of color extraction regions, is further configured to perform the steps of:
and step 11, acquiring a user picture presented by the display.
And step 12, according to a preset division rule, carrying out region division on the user picture to obtain a plurality of color extraction regions, wherein each color extraction region is not overlapped.
The controller acquires a user picture presented by the display and divides the user picture into a plurality of color extraction areas according to a preset division rule. The preset division rule may be to divide the user screen into a plurality of color extraction regions that do not overlap with each other, and a sum of the plurality of color extraction regions may be smaller than or equal to a complete region presented by the user screen.
A schematic diagram of a color extraction region according to some embodiments is illustrated in fig. 10. Referring to fig. 10, when a user screen is divided into four color extraction regions, the positions of the four color extraction regions may be located at four positions, i.e., upper, lower, left, and right positions of the user screen, respectively, and a first color extraction region a1A second color extraction area A on the upper side of the user screen2A third color extraction area A at the lower side of the user screen3On the left side of the user's screen, a fourth color extraction area A4Located on the right side of the user's view.
The number of the color extraction areas is the same as the set number of the peripheral equipment, so that the color extraction areas and the peripheral equipment are in one-to-one binding relationship, the color of one color extraction area is received by one peripheral equipment, the peripheral equipment can display the color of a user picture at the position of the corresponding area, confusion is avoided, and the effect that different peripheral equipment displays different colors is presented.
When the one-to-one binding relationship is established between the peripheral equipment and the color extraction area, the corresponding peripheral equipment is in a flashing state by triggering the name of the target peripheral equipment in the equipment list, so that the equipment to be bound is accurately determined. Then, based on the personalized setting of the user, the flickering peripheral equipment and one color extraction area can be bound. In order to facilitate consistency of colors of the user pictures presented by the peripheral equipment, the binding relationship between the peripheral equipment and the color extraction area can be established according to the same rule of the set positions.
The setting positions of the peripheral devices correspond one-to-one to the positions of the color extraction areas, for example, a first peripheral device 201a disposed on the upper side of the display and a first color extraction area a located on the upper side of the user screen1Correspondingly, the second peripheral device 201b arranged at the lower side of the display is connected with the second color extraction area A at the lower side of the user screen2Correspondingly, a third peripheral device 201c arranged on the left side of the display is associated with a third color extraction area A on the left side of the user screen3Correspondingly, the fourth peripheral device 201d disposed on the right side of the display is associated with the fourth color extraction area A on the right side of the user screen4And (7) corresponding.
And S2, acquiring the color characteristic value of the picture content presented in each color extraction area.
The divided color extraction regions are used for providing the displayed colors for the corresponding peripheral equipment, so that the color extraction can be carried out on the picture content presented in each color extraction region, and the color characteristic value corresponding to each color extraction region is determined. The color characteristic value can represent a color standard value of the corresponding color extraction area.
When the color characteristic value is determined, the color characteristic value can be directly extracted from each color extraction area, and a user picture displayed in a current display can be obtained firstly (namely, screenshot is firstly obtained), and then the color characteristic value of each color extraction area is extracted from the screenshot.
A flow chart of a method of extracting color feature values according to some embodiments is illustrated in fig. 11. In some embodiments, when direct extraction is employed, referring to fig. 11, the controller, in performing the obtaining of the color feature value of the picture content presented by each color extraction area, is further configured to perform the steps of:
s211, acquiring a color histogram of the picture content presented in each color extraction area.
And S212, extracting corresponding red pixel sum value, green pixel sum value and blue pixel sum value from each color histogram as a color characteristic value corresponding to each color extraction area.
Since each peripheral device presents only the color of the picture content presented by the color extraction area with which the binding relationship is generated, the controller can directly extract the color histogram of the picture content presented by each color extraction area. A color histogram is a color feature that describes the proportion of different colors in the entire image.
And extracting color characteristic values including a red pixel sum value, a green pixel sum value and a blue pixel sum value from a color histogram corresponding to the specified color extraction area. The red pixel sum may be 64RColor, which refers to the sum of the red pixel values of all colors in the designated picture content corresponding to the designated color extraction region; the green pixel sum may be 64GColor, which is the sum of the green pixel values of all colors in the designated picture content corresponding to the designated color extraction region; the total blue pixel value may be 64BColor, which refers to the total blue pixel value of all colors in the designated picture content corresponding to the designated color extraction area.
Each color extraction region corresponding to a color feature value, e.g., the first color extraction region A1Corresponding color characteristic value C1(64R1Color，64G1Color，64B1Color), the second Color extraction area a2Corresponding color characteristic value C2(64R2Color，64G2Color，64B2Color), the third Color extraction area a3Corresponding color characteristic value C3(64R3Color，64G3Color，64B3Color), the fourth Color extraction area a4Corresponding color characteristic value C4(64R4Color，64G4Color，64B4Color)。
Another method of extracting color feature values according to some embodiments is illustrated in fig. 12. In some embodiments, when the screenshot manner is adopted for extraction, referring to fig. 12, the controller, in executing the step of obtaining the color feature value of the picture content presented by each color extraction area, is further configured to execute the following steps:
s221, intercepting a complete picture presented in the user picture.
S222, dividing the complete picture according to the division rule of the color extraction areas, and determining the partial picture content corresponding to each color extraction area.
And S223, acquiring a color histogram of the partial picture content presented in each color extraction area.
And S224, extracting the corresponding red pixel sum value, green pixel sum value and blue pixel sum value from each color histogram as the color characteristic value corresponding to each color extraction area.
When the screenshot mode is adopted for extraction, the screen of the picture presented at a certain moment of the user picture can be firstly captured to obtain a complete picture. Then extracting the color histogram of each part of the complete picture, wherein the determination of each part in the complete picture can be divided based on a division rule for dividing a color extraction region, namely, the complete picture is divided into a plurality of partial pictures, each part corresponds to one partial picture, the partial pictures are not overlapped with each other, and the sum of the areas of the partial pictures is less than or equal to the total area of the complete picture.
The partial pictures obtained by each division are not overlapped, so that the color of each partial picture can be prevented from being influenced, and further, the representative color of the corresponding partial picture can be accurately extracted and presented on the external equipment. For example, if part of picture B1And partial picture B2With overlap, part of picture B1Red overall, partial picture B2The whole is yellow, and then the superposition results in a partial picture B1The whole color of the picture is red and yellow, and part of the picture B2The overall color of the image is yellow and reddish, so that the finally presented color is not the color originally presented by the corresponding partial image.
The number of the divided partial pictures of the complete picture is the same as the number of the divided partial pictures of the color extraction area, and the positions of the divided partial pictures are the same, namely if the color extraction area is four, and the positions of the color extraction area are respectively positioned at the upper position, the lower position, the left position and the right position of the user picture, the number of the divided partial pictures of the complete picture is also four, and the positions of the four partial pictures are also positioned at the upper position, the lower position, the left position and the right position of the complete picture.
After the complete picture is divided, each color extraction area corresponds to one partial picture content, and the color presented by the specified partial picture content is used as the color of the specified color extraction area. Upon determining the color that the specified partial screen content exhibits, a color histogram of the partial screen content may be obtained.
And extracting color characteristic values from a color histogram corresponding to the content of the partial picture, wherein the color characteristic values comprise a red pixel sum value, a green pixel sum value and a blue pixel sum value. The red pixel sum may be 64RColor, which refers to the sum of the red pixel values of all colors in the designated picture content corresponding to the designated color extraction region; the green pixel sum may be 64GColor, which is the sum of the green pixel values of all colors in the designated picture content corresponding to the designated color extraction region; the total blue pixel value may be 64BColor, which refers to the total blue pixel value of all colors in the designated picture content corresponding to the designated color extraction area.
Each partColor feature values corresponding to the partial screen contents as color feature values of the respective corresponding color extraction regions, and color feature values of one partial screen content as one color feature value of one color extraction region, e.g., partial screen content B1Color characteristic value C of1(64R1Color，64G1Color，64B1Color) as the first Color extraction region a1Corresponding color feature value, partial picture content B2Color characteristic value C of2(64R2Color，64G2Color，64B2Color) as the second Color extraction region A2Corresponding color feature value, partial picture content B3Color characteristic value C of3(64R3Color，64G3Color，64B3Color) as the third Color extraction region a3Corresponding color feature value, partial picture content B4Color characteristic value C of4(64R4Color，64G4Color，64B4Color) as the fourth Color extraction region a4The corresponding color feature value.

After the color feature values (the combined red, green, and blue pixels) of each color extraction region are determined, the color feature values can be converted into the RGB mean value of the RGB color space. During conversion, the RGB mean value is determined by calculating the mean value of the three primary colors (red, green, and blue) in the RGB color space by using the pixel area of each color extraction region.
