Abstract

Embodiments of the present invention provide a method, an apparatus, and a storage medium for playing control processing of an audio file. The method may include: acquiring an album image corresponding to an audio file to be processed; performing color analysis on the album image, to determine playing colors of the audio file; and performing the playing control processing on the audio file by using the determined playing colors. In the embodiments of the present invention, a personalized playing color can be determined for an audio file, and the playing color of the audio file can effectively represent a style property of the audio file, thereby improving intelligence of playing control processing of the audio file.

First claim

1 . A method for playing control processing of an audio file, comprising:
acquiring an album image corresponding to an audio file to be processed; performing color analysis on the album image, to determine playing colors of the audio file by:
acquiring colors of specified pixel points of the album image,
extracting a preset quantity of feature colors from the colors of the specified pixel points of the album image, and
determining the preset quantity of feature colors as playing colors of the audio file; and
performing the playing control processing on the audio file by using the determined playing colors.

2 . (canceled)

3 . The method according to claim 1 , after the extracting a preset quantity of feature colors from the colors of the specified pixel points of the album image, further comprising:
performing a mapping processing on the preset quantity of feature colors, to obtain the preset quantity of mapped colors, wherein the determining the preset quantity of feature colors as the playing colors of the audio file comprises: determining the preset quantity of mapped colors as the playing colors of the audio file.

4 . The method according to claim 3 , wherein the performing a mapping processing on the preset quantity of feature colors, to obtain the preset quantity of mapped colors comprises:
reading a preset first color mapping table, the preset first color mapping table comprising at least one mapped color and a color value range of each mapped color; acquiring a color value of each feature color of the preset quantity of feature colors; and mapping each feature color of the preset quantity of feature colors as a mapped color in the preset first color mapping table according to the preset first color mapping table and the color value of each feature color of the preset quantity of feature colors.

5 . The method according to claim 3 , wherein the performing mapping processing on the preset quantity of feature colors, to obtain the preset quantity of mapped colors comprises:
reading a preset second color mapping table, the preset second color mapping table comprising at least one mapped color and a color value of each mapped color; acquiring a color value of each feature color of the preset quantity of feature colors; calculating a Euclidean distance between each feature color of the preset quantity of feature colors and each mapped color in the preset second color mapping table; and for each current feature color of the preset quantity of feature colors, determining a mapped color, having a minimum Euclidean distance from a current feature color, in the preset second color mapping table as a mapped color of the current feature color, to obtain the preset quantity of mapped colors.

6 . The method according to claim 1 , wherein the performing the playing control processing on the audio file by using the determined playing color comprises:
performing a color rendering processing on a playing interface of the audio file by using the determined playing colors when a playing request of the audio file is detected; and outputting the playing interface of the audio file after the color rendering processing.

7 . The method according to claim 6 , wherein the performing a color rendering processing on a playing interface of the audio file by using the determined playing colors comprises:
determining a color rendering processing area in the playing interface of the audio file according to a preset area range; selecting, from the determined playing colors, at least one playing color as a background color, and performing the color rendering processing on a background of the color rendering processing area; and selecting, from playing colors other than the background color of the determined playing colors, at least one playing color as a font color, and performing color rendering processing on a font of the color rendering processing area.

8 . An apparatus for playing control processing of an audio file, comprising:
an image acquisition module, configured to acquire an album image corresponding to an audio file to be processed; an analysis module, configured to perform color analysis on the album image, to determine playing colors of the audio file, the analysis module comprising:
a color acquisition unit, configured to acquire colors of specified pixel points of the album image,
an extracting unit, configured to extract a preset quantity of feature colors from the colors of the specified pixel points of the album image, and
a determining unit, configured to determine the preset quantity of feature colors as playing colors of the audio file; and
a playing control processing module, configured to perform playing control processing on the audio file by using the determined playing colors.

9 . (canceled)

10 . The apparatus according to claim 8 , wherein the analysis module further comprises:
a mapping processing unit, configured to perform a mapping processing on the preset quantity of feature colors, to obtain the preset quantity of mapped colors, wherein the determining unit is configured to determine the preset quantity of mapped colors as the playing colors of the audio file.

11 . The apparatus according to claim 10 , wherein the mapping processing unit comprises:
a first reading subunit, configured to read a preset first color mapping table, the preset first color mapping table comprising at least one mapped color and a color value range of each mapped color; the first acquiring subunit, configured to acquire a color value of each feature color of the preset quantity of feature colors; and a first mapping subunit, configured to map each feature color of the preset quantity of feature colors as a mapped color in the preset first color mapping table according to the preset first color mapping table and the color value of each feature color of the preset quantity of feature colors.

12 . The apparatus according to claim 10 , wherein the mapping processing unit comprises:
a second reading subunit, configured to read a preset second color mapping table, the preset second color mapping table comprising at least one mapped color and a color value of each mapped color; a second acquiring subunit, configured to acquire a color value of each feature color of the preset quantity of feature colors; a distance calculation subunit, configured to calculate a Euclidean distance between each feature color of the preset quantity of feature colors and each mapped color in the preset second color mapping table; and a second mapping subunit, configured to: for each current feature color of the preset quantity of feature colors, determine a mapped color, having a minimum Euclidean distance from a current feature color, in the preset second color mapping table as a mapped color of the current feature color, to obtain the preset quantity of mapped colors.

13 . The apparatus according to claim 8 , wherein the playing control processing module comprises:
