In S203, with described Watermark-adding in described multi-medium data.
In the present embodiment, according to the user speech input speed, it is character data that Real time identification is changed described speech data, and makes watermark according to described character in real time, has realized that synchronous phonetic entry and watermark show.
In the present embodiment, carry out buffer memory by the character that will identify conversion, when buffer memory during whole character to be added, make watermark according to described character again, so that show more accurately the content to be added that the user inputs.
Embodiment three
Fig. 3 shows the process flow diagram of the realization of the method for adding watermark in the multi-medium data that the embodiment of the invention three provides, and wherein, described multi-medium data is image data, and details are as follows for described method:
In S301, when receiving the instruction of user add watermark, record the speech data of user's input.
In S302, identify described speech data, with the speech data changed after the identification, and according to described character making watermark.
In the present embodiment, the implementation of S201 and S202 is similar among the implementation of S301 and S302 and the embodiment two, specifically can with reference to the description that is S201 and S202 among the embodiment two, not repeat them here.
In S303, convert described watermark to memory bitmap;
In the present embodiment, described bitmap color can be set according to user's request, for example can be set as the memory bitmap of white gravoply, with black engraved characters, can certainly be set to other color.
In S304, described memory bitmap and described image data are superposeed, and the background of described memory bitmap is set to transparent.
In the present embodiment, when described memory bitmap is the black and white memory bitmap, can be transparent by with the pixel value of pixel in the bitmap being that the point of (255,255,255) is set to, then can be implemented in the character data that only shows black in the memory bitmap.
For the ease of understanding, the realization example concrete with the next one describes adding the watermark process in the multi-medium data of present embodiment, but the situation with this realization example is not limited, suppose that the terminal user will add watermark " 2012 Great Wall, China " in the photo of current terminal device storage, then adding procedure is:
1, opens the photo of wanting to add watermark at terminal device.
2, when receiving the instruction of user add watermark, record the speech data " 2012 Great Wall, China " of user's input.
3, identify described speech data, with speech data changed and the buffer memory after the identification, when buffer memory during whole character to be added, make watermark according to the character of buffer memory.
4, when receiving the instruction of adding the watermark end, convert described watermark to memory bitmap;
5, described memory bitmap and described picture data are superposeed, and the background of described memory bitmap is set to transparent;
Wherein, the background by memory bitmap is set to transparent, and then the character in the bitmap can be synthetic with the photo background colour, coordinates mutually with the photo background so that show character.
The information whether 6, the picture data after the terminal device demonstration interpolation watermark, and output prompting user preserves the picture data of described interpolation watermark.
In the present embodiment, when multi-medium data is image data, by converting described watermark to memory bitmap, and described memory bitmap and described image data superposeed, and the background of described memory bitmap is set to transparent, thereby realize that with described Watermark-adding in described multi-medium data, method is simple, convenient.
