The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) or a stable nonvolatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure shown in fig. 1 does not constitute a limitation of the background-color-generating apparatus, and may include more or fewer components than shown, or may combine certain components, or may be arranged in a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and a background color generation program may be included in the memory 1005 as one type of storage medium.
In the background-color-generation apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the background color generation apparatus of the present invention may be provided in the background color generation apparatus, which calls the background color generation program stored in the memory 1005 through the processor 1001 and executes the background color generation method provided by the embodiment of the present invention.
An embodiment of the present invention provides a background color generation method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the background color generation method of the present invention.
In this embodiment, the background color generation method includes the following steps:
step S10: and acquiring color parameters of each pixel point in the film and television cover diagram in an HSV color space, wherein the color parameters comprise hue components, saturation components and brightness components.
It should be noted that, the execution body of the method of the embodiment may be a computing service device with background color generation, network communication and program running functions, for example, a projector, a television, a mobile phone, a tablet computer, a personal computer, etc., or may be other electronic devices that implement the same or similar functions. The present embodiment and the following embodiments will be described below with reference to the above-described background-color generation apparatus.
It is understood that the aforementioned video cover map may be a cover map of a video work that is directly presented to a user.
The HSV is a color pattern that uses three attributes of colors to represent colors. In HSV mode, three attributes are H, S and V, respectively, where H (Hues) represents hue, S (Saturation) represents Saturation, and V (Value) represents brightness. HSV color patterns are based on human perception of color, describing three basic characteristics of color.
In a specific implementation, the background color generating device may respond to the user-triggered details page display of the movie work to perform an operation of acquiring color parameters of each pixel point in the HSV color space in the movie cover map, or may perform an operation of acquiring color parameters of each pixel point in the HSV color space in the movie cover map when the device is in an idle state, which is not limited in this embodiment. The method comprises the following steps: and traversing each pixel point in the film and television cover map, and then determining the H component, the S component and the V component of the color parameters of each pixel point in the HSV color space.
Further, in order to improve the accuracy of the color parameter acquisition, in this embodiment, the step S10 includes:
step S101: and acquiring a film and television cover source diagram corresponding to the film and television cover diagram.
The source image of the film and television cover is an original image which can be directly accessed and processed by the background color generation device.
In a specific implementation, when the background color generating device detects that the background color of the page detail page needs to be generated, the source diagram of the film and television cover diagram can be acquired.
Step S102: and carrying out bitmap conversion on the film and television cover source map to obtain a film and television cover bitmap.
The video cover bitmap may be a picture composed of a single dot of pixels. Because the film and television cover picture formed by the pixel points has the theme color, each pixel point also has the corresponding color parameter.
In a specific implementation, the background color generation device may convert the color cover source map into a bitmap, thereby obtaining a video cover bitmap composed of single pixels.
Step S103: and traversing each pixel point in the film and television cover bitmap to obtain the color parameters of each pixel point in the HSV color space.
In a specific implementation, the background color generating device may traverse each pixel point in the bitmap of the film and television cover, and determine a color parameter of each pixel point in the HSV generating space; RGB color parameters for each pixel point may also be determined and then converted into color parameters in the HSV generation space, i.e., HSV color parameters. Because the HSV color parameters are determined by traversing each pixel point in the film and television cover bitmap, the accuracy of acquiring the HSV color parameters is effectively improved.
Step S20: extracting to-be-processed color parameters, wherein the saturation component is in a preset saturation range, and the brightness component is in a preset brightness range, from the color parameters.
Correspondingly, in this embodiment, the preset saturation range is 10% -70%, and the preset brightness range is 40% -44%.
In a specific implementation, the background color generating device may filter the acquired HSV color parameters according to the preset saturation component and the preset brightness range, filter color parameters in which the saturation component (S component) in each color parameter is not in the preset saturation range and the brightness component (V component) in each color parameter is not in the preset brightness range, so that the saturation component (S component) in each remaining color parameter is in the preset saturation range, the brightness component (V component) is in the color parameter in the preset brightness range, and extract each remaining color parameter to obtain the color parameter to be processed.
It should be understood that, the color parameters of each pixel point in the HSV color space in the film and television cover chart represent the theme color of the film and television cover chart, and if the background color of the film and television detail page is directly generated by the theme color, the background color of the film and television detail page is consistent with the theme color, so that the visual experience is affected. And the saturation component (S component) in the color parameters is controlled to be kept in the preset saturation range and the brightness component (V component) is controlled to be kept in the preset brightness range, so that the background color of the color detail page generated by the color parameters to be processed is obviously different from the color parameters of the theme color, the background color of the detail page is prevented from being consistent with the theme color, the bitmap of visual experience is influenced, and the problem that the theme color is too bright is also avoided.
Step S30: and generating the background color of the movie and television detail page according to the color parameters to be processed.
It should be noted that, the movie detail page may be a detail page that is displayed to the user and describes the movie work. The movie detail page may include a movie cover map, a UI, and a text introduction.
In a specific implementation, the background color generating device may use the to-be-processed color parameter as a background color of the movie and television detail page, and since a saturation component (S component) in the to-be-processed color parameter is in the preset saturation range and a brightness component (V component) is in a color parameter in the preset brightness range, the to-be-processed color parameter may be obviously different from a theme color of the movie and television cover map, so that a problem that other elements on the movie and television detail page become unclear due to a color close to the theme color of the movie and television cover is effectively avoided.
According to the embodiment, color parameters of each pixel point in the film and television cover diagram in an HSV color space are obtained, wherein the color parameters comprise hue components, saturation components and brightness components; then extracting to-be-processed color parameters of which the saturation component is in a preset saturation range and the brightness component is in a preset brightness range from the color parameters; and finally, generating the background color of the movie and television detail page according to the color parameters to be processed. According to the method, the to-be-processed color parameters with the saturation component in the preset saturation range and the brightness component in the preset brightness range are extracted from the color parameters, so that the background color of the movie and television detail page is different from the theme color of the movie and television cover map. According to the page generation method, through the strategy of filtering the color parameters, in which the saturation component and the brightness component in the color parameters are not in the preset dark color parameter range, the problem that other elements on the background color of the conventional film and television detail page become unclear due to similar colors is avoided, and the visual experience of a user is effectively improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a background color generation method according to the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S301: and accumulating the occurrence times of each color parameter in the color parameters to be processed.
It should be noted that, if the color range of the theme color of the film and television cover chart is larger, the number of to-be-processed color parameters in which the brightness component is in the preset brightness range and the saturation component is in the preset saturation range is larger, if the to-be-processed color parameters are directly used for generating the background color of the film and television detail page, multiple colors are contained in the background color, so that the generated background color is not accurate enough. The present embodiment is therefore presented so that the exact appropriate color can be extracted under any video cover map.
In a specific implementation, the background color generation device counts the number of pixels with the same color parameters (H, S, V components are the same) in each pixel in the film and television cover map.
Step S302: and extracting the target color parameter with the largest occurrence number of the color parameters in the color parameters to be processed.
In a specific implementation, the background color generation device may use the color parameter with the largest occurrence number of the color parameters in the color parameters to be processed as a final theme color, and then extract the final theme color, and use the final theme color as the target color parameter. The method is used for extracting the target color parameter with the largest occurrence frequency of the color parameter, and the background color generated by using the target color parameter does not have the problem that the background color contains multiple colors, so that the generated background color is accurate and proper.
It should be understood that the background color generation apparatus may also count the number of occurrences of each color parameter before filtering the color parameter, that is, while acquiring the HSV color parameter, and even if the number and magnitude relationship of the remaining color parameters is still accurate. Because the HSV color parameters are taken, the occurrence times of the color parameters are counted, the processing efficiency can be effectively improved, and the resource consumption is reduced.
Step S303: and combining the target color parameter with a preset gradient color to generate a background color of the movie and television detail page.
It should be noted that the preset gradient color may be a gradient color that enables the target color parameter and other elements on the page detail page to be perfectly fused. The gradual color change may be white with gradually changing transparency, with an ARGB range of (255, 255, 255, 255) to (0, 255, 255, 255).
In a specific implementation, the background color generating device can use the extracted target color parameter as an initial background color of the movie and television detail page, and then superimpose the preset gradient color on the initial background color, so that the target color parameter and the preset gradient color are combined, and the combined final color is used as the background color of the color detail page, so that the target color parameter can be perfectly fused with other elements on the page, and the phenomenon that other elements on the movie and television detail page are similar to the target color parameter and are not clear enough is avoided.
It should be appreciated that after the background color of the video detail page is generated, the video detail page may be saved locally, and if the user inputs a viewing instruction of the video detail page, the video detail page of the background color may be presented to the user.
For ease of understanding, the description is given with reference to fig. 4, but the present solution is not limited thereto. Fig. 4 is an overall flowchart of background color generation in the second embodiment of the background color generation method of the present invention, in fig. 4, a cover work diagram is obtained first, the cover work diagram may be the film and television cover diagram, then the cover work diagram is converted into a Bitmap, the Bitmap may be the film and television cover Bitmap, then all pixel points in the Bitmap are traversed, whether the S component in the color parameters of each pixel point is between 10% and 70%, and whether V is between 40% and 44%, if not, the color parameters are discarded, that is, the color parameters are filtered, if yes, the number of times of the colors is accumulated, the color parameters with the largest number of times are taken out, then the color parameters with the largest number of times are taken as the theme color, the theme color is the target color parameter, then the theme color is combined with the gradient color, that is, the background color of the film and television detail page may be the preset gradient color, and finally the film and television detail page of the background color may be displayed.
Further, in order to improve the efficiency of generating the background color of the movie detail page, in this embodiment, the step S303 includes:
step S3031: and adding the target color parameters to a background color base map of the movie detail page.
In a specific implementation, the background color generation device may fill the target color parameter into the movie detail page, and use the target color parameter as a background color base map of the movie detail page.
Step S3032: and superposing preset gradient color in a preset gradient area of the film and television detail page to generate a combined color of the target color parameter and the preset gradient color combination.
It should be noted that the preset gradual change area may be an area flush with the movie cover map in the preset detail page, such as an area of [0,0] - [1920, 448] of the movie detail page.
In a specific implementation, the background color generating device may superimpose a preset gradient color of an ARGB (255, 255, 255, 255) layer in a preset gradient region, such as a region from [0,0] to [1920, 448] of the movie detail page, on the basis that a background movie base map of the movie detail page is the target color parameter, so as to generate a combined color of the target color parameter and the preset gradient color, where the combined color effect may be the background color of the whole page. Wherein, in the preset gradual change region, the transparency of the preset gradual change color gradually decreases along the preset direction (from top to bottom).
Step S3033: and taking the combined color as a background color of the movie detail page.
In a specific implementation, the background color generation device may use the combined film and television as a background color of a final film and television detail page.
It should be understood that, in this embodiment, the target color parameter is added to the background color base map of the movie detail page, then the preset gradient is superimposed on the preset gradient area of the movie detail page, so as to generate a combined color of the target color parameter and the preset gradient color, and finally the combined color is used as the background color of the movie detail page.
For ease of understanding, reference is made to fig. 5, but this solution is not limited thereto. Fig. 5 is a schematic diagram of a movie detail page in a second embodiment of the background color generation method of the present invention, where the rectangular UI in the upper left area of the movie detail page in fig. 5 may be a movie cover diagram, and the area outside the rectangular UI may be other elements in the movie detail page. The background color of the movie detail page may be the background color generated by the embodiment, and the preset gradient color may be superimposed on the position flush with the movie cover map. The background color is filtered by a preset filtering strategy and is generated by the color parameter which accords with the preset dark color parameter range and has the largest range, so that the background color is obviously different from the theme color of the film and television cover map, and the user can conveniently distinguish the background color from the theme color of the film and television cover map.
Referring to fig. 6, fig. 6 is a flowchart of a third embodiment of a background color generation method according to the present invention.
Based on the above embodiments, in this embodiment, before step S20, the method further includes:
step S21: and judging whether the saturation component in each color parameter reaches a preset black-and-white component threshold value.
It should be noted that, if the film and television cover chart is a black-and-white picture, the HSV color parameter extracted from the film and television cover chart may not fall within the preset dark color parameter range, so that the background color of the film and television detail page cannot be accurately extracted.
It is understood that the above-mentioned predetermined black-and-white component threshold may be a threshold at which the saturation component in the color parameter reaches the saturation level in the black-and-white picture, that is, if the saturation component (S component) in the color parameter is less than or equal to the predetermined black-and-white threshold, the color parameter may be determined to be black-and-white, otherwise, if the saturation component (S component) in the color parameter is greater than the predetermined black-and-white threshold, the color parameter may be determined not to be black-and-white.
In a specific implementation, the background color generation device may determine whether the film and television cover chart is a black and white picture through the saturation component in the color parameter, that is, determine whether the saturation component (S component) in each HSV color parameter of the obtained film and television cover chart reaches the preset black and white component threshold.
Step S22: and if the preset black-and-white component threshold is not reached, judging that the film and television cover picture is a black-and-white picture.
In a specific implementation, the background color generation device may determine that the preset cover map is a black-and-white picture when it is determined that the saturation component (S component) in each HSV color parameter does not reach the preset black-and-white component threshold, that is, is less than or equal to the preset black-and-white component threshold.
Step S23: and when the film and television cover map is a black-and-white picture, acquiring a preset specified color parameter, and taking the preset specified color parameter as the background color of the film and television detail page.
It should be noted that the above predetermined specified color parameters may be set by a skilled person, and specific color parameters for black-and-white pictures, such as RGB (60, 68, 70).
In a specific implementation, when the background color generating device determines that the preset cover chart is a black-and-white picture, the preset specified color parameter may be obtained, and the preset specified color parameter is directly used as the background color of the movie and television detail page, so as to avoid the problem that if the operation of the embodiment is performed by using the black-and-white movie and television cover chart, the extracted HSV color parameter cannot fall in the preset dark color parameter range, and thus the background color of the movie and television detail page cannot be accurately extracted.
Accordingly, in this embodiment, after step S21, the method further includes:
step S22': and if the preset black-and-white component threshold value is reached, judging that the film and television cover picture is not a black-and-white picture.
In a specific implementation, the background color generation device may determine that the preset cover map is not a black-and-white picture when determining that the saturation component (S component) in each HSV color parameter reaches the preset black-and-white component threshold, that is, is greater than the preset black-and-white component threshold.
Step S23': and when the film and television cover map is not a black-and-white picture, executing the step of filtering each color parameter based on a preset filtering strategy to obtain the color parameter to be processed.
In a specific implementation, when the background color generating device determines that the preset cover chart is not a black-and-white picture, the step of determining that the acquired color parameters can be performed through the preset filtering policy, and filtering each color parameter based on the preset filtering policy to obtain the color parameters to be processed can be performed.
It should be understood that, in this embodiment, whether the film and television cover picture is a black and white picture is determined by determining whether the saturation component in each color parameter reaches the preset black and white component threshold, if the film and television cover picture is a black and white picture, the preset designated color parameter is used as the background color of the film and television detail page, if the film and television cover picture is not a black and white picture, the step of filtering each color parameter based on the preset filtering policy to obtain the color parameter to be processed is performed, and the background color of the film and television detail page is generated by the method of the embodiment, so that the generated background color is not affected by various cover pictures, and the accurate and proper theme color is extracted.
In addition, an embodiment of the present invention also proposes a storage medium having stored thereon a background-color generation program which, when executed by a processor, implements the steps of the background-color generation method as described above.
Referring to fig. 7, fig. 7 is a block diagram showing the structure of a first embodiment of the background color generation apparatus of the present invention.
As shown in fig. 7, the background color generation apparatus provided by the embodiment of the present invention includes:
the color acquisition module 501 is configured to acquire color parameters of each pixel point in the film and television cover map in the HSV color space.
The color filtering module 502 is configured to filter each color parameter based on a preset filtering policy, and obtain a color parameter to be processed, where the preset filtering policy is a policy for filtering color parameters in which a saturation component and a brightness component in each color parameter are not in a preset dark color parameter range.
And the color generation module 503 is configured to generate a background color of the movie and television detail page according to the to-be-processed color parameter.
According to the embodiment, color parameters of each pixel point in the film and television cover diagram in an HSV color space are obtained, wherein the color parameters comprise hue components, saturation components and brightness components; then extracting to-be-processed color parameters of which the saturation component is in a preset saturation range and the brightness component is in a preset brightness range from the color parameters; and finally, generating the background color of the movie and television detail page according to the color parameters to be processed. According to the method, the to-be-processed color parameters with the saturation component in the preset saturation range and the brightness component in the preset brightness range are extracted from the color parameters, so that the background color of the movie and television detail page is different from the theme color of the movie and television cover map. According to the page generation method, through the strategy of filtering the color parameters, in which the saturation component and the brightness component in the color parameters are not in the preset dark color parameter range, the problem that other elements on the background color of the conventional film and television detail page become unclear due to similar colors is avoided, and the visual experience of a user is effectively improved.
