When the electronic device broadcasts an image data on the display screen, the electronic device checks the image data and judges the screen image data specification can not meet and show other specifications, and then the electronic device handles the image data and shows the image data on the screen in other specification.
Description
Technical field
The method that the present invention handles relevant for image data, especially refer to a kind of electronic installation inspection and judge this image data and can't support and show other picture specifications, then this image data is carried out image processing and be shown on this display screen with another picture specification, so, make this image data unlikely because of picture itself that can't support other picture specification display distortions on this display screen.
Background technology
The world that we faced is an Information of Science and Technologyization now, the epoch that electronic industry is flourish, the high-tech product development that various computer electronic products are derived rapidly, these products interweave together layer by layer with our life, it is for the development of multimedia image, shortened considerable distance, along with present portable type audio and video player (Personal Media Playe, PMP)) high utilization rate)))))), and under the adding fuel to the flames of each many inducement of tame manufacturer, competition on the market is more and more fierce, each big multimedia video and audio product manufacturer all constantly weeds out the old and bring forth the new, for to upgrade, more skilful at attracting liking of many users, and the user watches that for the portable type audio and video player quality requirements is more and more higher.
Multimedia video product consumption in the market is increasing, and the image money section of present film market made all adopts with 16: 9, the variable wide screen specification of (even 2.35: 1) the ratio of width to height, and peddle or all support the variable wide screen specification of 16: 9 the ratio of width to height pictures on the market by the DVD image format of being downloaded on the network, yet, the partial image data that still has the multimedia video product to be play can't be supported the variable wide screen specification of 16: 9 the ratio of width to height pictures, (Dynamic Control Widescreen)
These the multimedia video products that can't support variable wide screen form are still at present and carry out picture with direct picture tailoring technique (Direct Tailor) and horizontal compression technology (Squeeze) dual mode and handle when the image of DVD playing back form:
1, direct picture tailoring technique
This direct picture tailoring technique is as the term suggests be the technology that part that this multimedia video product has more raw frames the right and left with software is directly carried out cutting, see also shown in Figure 1, this figure is the raw frames 100 of not supporting 16: 9 the ratio of width to height of one of variable wide screen specification that film company makes, if these raw frames 100 the right and lefts are directly carried out cutting, see also shown in Figure 2, then the right and left of this raw frames part will be given cutting and be formed a processing picture 200, therefore work as Fig. 1,2 compare, the raw frames 100 that can obviously feel 16: 9 the ratio of width to height is after direct picture tailoring technique cutting, this processing picture 200 has changed 100 original presenting of this raw frames, also has been offset the original original idea of creator of this raw frames 100.
2, horizontal compression technology
This horizontal compression technology is a method that can make wide screen fully apply to all vertical scanning linear, picture signal with script wide screen ratio, vertical direction in wide screen remains unchanged, but then be compressed in the horizontal direction of wide screen and make the aspect ratio that becomes 4: 3 the ratio of width to height, such signal of video signal is delivered to 4: 3 the ratio of width to height can find that picture has taken whole screen, see also shown in Figure 3, this figure is another raw frames 300 of not supporting 16: 9 the ratio of width to height of one of variable wide screen specification that film company makes, Fig. 4 forms another processing picture 400 for the horizontal direction of another raw frames 300 then being compressed the back, therefore work as Fig. 3,4 compare, another raw frames 300 that can obviously feel 16: 9 the ratio of width to height is after the horizontal compression technology is compressed, this another handle picture 400 after vertical direction is stretched, changed 300 original presenting of this another raw frames, also make this another handle picture 400 and produce the sensation of not harmony.
So, if adopt with this two technology to these raw frames 100,300 image is handled, first because the image of this raw frames 100 is subjected to direct picture tailoring technique cutting the part details of this raw frames 100, can not embody film creation person's original idea, another is then because the image of this another raw frames 300 is subjected to the horizontal compression technology that its vertical direction is stretched and therefore distortion, so, how to design a kind of electronic installation conversion and do not support the method for the image data of other picture specifications, make the user when using this multimedia video product, still can appreciate the image of former spiritedness in 4: 3 the ratio of width to height screens of this multimedia video product, be the dealer of this area in fact, need to be resolved hurrily and improved important topic.
