Embodiment approach

[0150] In this embodiment, the step S520 includes:

[0151] The three-dimensional image data associated with the sound data is analyzed according to the original sensory sound source position corresponding to the sounding object, and the left-eye image content information and the right-eye image content information corresponding to the sounding object are obtained.

[0152] For details of this step, refer to the step of helping to determine the image content information of the corresponding sounding object in the image data according to the original sensory sound source position corresponding to the sounding object in the above method embodiment, which will not be repeated here.

[0153] For a detailed description of each step of the embodiment method of the present application, see Figure 1 to Figure 4 Corresponding descriptions in the shown method embodiments are not repeated here.

[0154] like Figure 6 As shown, the embodiment of the present application also provides a...

Abstract

The embodiment of the invention discloses a multimedia processing method and a multimedia processing device. The method includes the steps of determining a sounding object according to sound data, analyzing image data associated with the sound data to obtain image content information corresponding to the sounding object, obtaining the position of the user relative to a display screen used for presenting the image data, obtaining display parameters of the display screen, and determining a feeling sound source position of the sounding object relative to the user according to the position of the user relative to the display screen, the display parameters of the display screen and the image content information. By means of a multimedia processing technique, different multimedia presenting devices and different user positions can obtain the feeling sound source position and a vision feeding position of the same object in the multimedia presenting process.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular to a multimedia processing method and a multimedia processing device. Background technique [0002] Current multimedia devices usually include two parts: image display and sound playback. Since image display and sound playback are usually completed by different devices, these two parts generally only have a temporal relationship, not a spatial relationship. The size of common multimedia devices ranges from a few inches (such as mobile phone equipment, tablet computers) to dozens of inches (such as notebooks, desktops, TV screens) to hundreds of inches (outdoor advertising screens), and the corresponding sound The size and distribution of playback devices will also vary greatly. The inventors of the present application found that most of the current video file formats do not consider the spatial information of the sound, which makes it difficult for the client to accur...
