Background technology

In recent years, people are more and more deep in the research of image processing field, many new processing methods and Processing Algorithm have occurred, but thing followed problem is the checking work to the treatment effect of these methods and algorithm.Generally be that the image that will dispose saves as the picture of forms such as BMP, JPEG or sequence image is converted into video flowing and plays, come observing effect with this.

In the prior art, a kind of way is to utilize some softwares with the aid of pictures to come observing effect.The shortcoming of doing like this is very obvious: the first, if image is saved as the picture of forms such as BMP, JPEG, observe with software with the aid of pictures then, and will be subjected to the size of display, the influence of resolution so.And though software with the aid of pictures itself has the function of convergent-divergent, this convergent-divergent is to utilize the processing of interpolation algorithm to a kind of distortion of image, is not that we want the most real image observed.The second, if utilize software with the aid of pictures that image is carried out frame by frame broadcast, come observing effect with this, will cause the shake effect of image so, neither we wanted.

In the prior art, another kind of way is to be video code flow with the image transitions after handling, form such as MPEG2 for example, and then with corresponding playout software broadcast, this method also has its drawback.Because these video formats all are to adopt the lossy compression method algorithm, thereby meeting lost part image information, our observed image neither be true and reliable like this.And when simultaneously we play with playout software, playout software can adopt the algorithm of self that image is carried out enhancement process, therefore can bring distortion like this, so the effect that this method is observed also is not enough to be accepted and believed.

Because existing display terminal generally can only correctly show rgb signal, so cited embodiment all in the end is converted to RGB with YUV signal, if but display terminal is supported YUV signal, we also can be without the conversion of color space converting unit 15, and directly export video interface unit 13 to from mode switching unit 16, because other process is all basic identical, so also do not repeat to set forth at this.

Above disclosed only is the preferred embodiments of the present invention, can not limit interest field of the present invention with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
