Unlike, first area is that the color parameter value based on each pixel in original image generates, i.e., the
One region only includes the color parameter value of original image, and in other words, each color channel of first area preserves above-mentioned color
Colour parameter value.It should be noted that then each color channel of first area saves above-mentioned color ginseng by taking RGB parameter value as an example
The meaning of numerical value are as follows: the channel R of first area is used to save G parameter value for saving R parameter value, the channel G of first area, the
The channel B in one region is for saving B parameter value.That is, various color parameter values are stored in matched color channel.
And second area is that the transparency parameter value based on each pixel in original image generates, i.e. second area
It only include the transparency parameter value of original image, in other words, any one color in each color channel of second area
Channel is used to save above-mentioned transparency parameter value.Continue by taking RGB mode as an example, then this is for saving above-mentioned transparency parameter value
Color channel can be any of for the channel R, the channel G and channel B.Above-mentioned transparency ginseng is not saved for other two
The color channel of numerical value not will do it the preservation of other color informations usually in embodiments of the present invention.
In summary, it will not be lost after carrying out Video Composition due to the data in color channel, in order to
The loss of transparence information is avoided, transparence information is stored in color channel by the embodiment of the present invention.Further, since the firstth area
Each color channel in domain preserves the color information of original image, then carries out the preservation of transparence information and can cause color information
Transparence information is stored in its of second area by the problem of obscuring together with transparence information, therefore, the embodiment of the present invention
In in a color channel, the color channel for saving transparence information herein can be any one color channel of second area.
In addition, it is necessary to explanation is a bit, it is specifically to lead to the G that transparency parameter value has been stored in second area in Fig. 2
In road, so it is green that the subregional color of right side, which is substantially,.Similarly, if transparency parameter value has been stored in second
In the channel R in region, then the subregional color of right side is just red, and if transparency parameter value has been stored in second area
Channel B in, then the subregional color of right side be just blue.And left-half is just the normal display color of original image.
Wherein, above-mentioned that the treatment process application code of Target Photo is generated come when realizing by original image, main journey
