2And R
nThe form of the stereo-picture that 110 conversion of video format conversion equipment receive is to be consistent with the form that can be shown device 120 processing.More particularly, video format conversion equipment 110 increases or reduces the stereo-picture that receives in proportion with the resolution that is suitable for display unit 120, the form of the frame of conversion stereo-picture, and output has the stereo-picture of the form that is suitable for display unit 120.Because the signal that display unit 120 common receptions and processing are consistent with VESA (VESA) standard so video format conversion equipment 110 produces the vision signal that is consistent with the VESA standard, and sends to display unit 120 with this vision signal.
In order to produce the video format that is suitable for display unit 120, video format conversion equipment 110 receives characteristic information about display unit 120 to find the characteristic of display unit 120 through outside port.Characteristic information and outside port about display unit 120 will be described subsequently.
Fig. 2 is the block diagram of video format conversion equipment according to an exemplary embodiment of the present invention.The video format conversion equipment comprises scaler 210, memory 220, user interface section 230, video switch 240 and formatter 250.Scaler 210 comprises that first scaler 212 and second scaler 214 are to handle stereo-picture.If the processing multidimensional image, then according to dimension may needs than first scaler 212 and second scaler, 214 more scaler.
Scaler 210 receives multidimensional image, and this multidimensional image of convergent-divergent is to be consistent with exploration on display resolution ratio.For example, display unit is configured to show the image that has such as specific formats such as 720 * 480 forms, 1024 * 768 forms.The resolution of the multidimensional image that therefore, receives is transformed to be consistent with this display unit resolution.Horizontal transformation may be different with vertical conversion, and the zoom operations of left image and right image may be performed with different ratios.
The form of the image of formatter 250 conversion convergent-divergents is to be consistent with the characteristic of this display unit.To 4F the video format conversion be described with reference to figure 4A subsequently.
Fig. 3 is the more detailed block diagram of formatter according to an exemplary embodiment of the present invention.Formatter comprises format conversion unit 310, selected cell 320 and display interface unit 330.Format conversion unit 310 produces left image with different-format and the right image that receives.In order to realize this purpose, format conversion unit 310 comprises progressive format converter 311, by pixel format converter 312, top-down format converter 313, by a format converter 314, format converter 315 and separation of images format converter 316 from left to right frame by frame.Progressive format, by pixel format, top-down form, by a form, frame by frame form and from left to right the separation of images form will be described to 4F with reference to figure 4A subsequently.
Selected cell 320 is selected by the accessible form of display unit in the form that is produced by format conversion unit 310.The image transform that display interface unit 330 will have the form of selection becomes display unit acceptable image signal, and exports this picture signal.Because image is produced based on the VESA standard usually, so 330 outputs of display interface unit have the image of VESA form.
Fig. 4 A illustrates different video formats to 4F.Fig. 4 A illustrates image line by line, and Fig. 4 B illustrates the image by pixel, and Fig. 4 C illustrates top-down image, and Fig. 4 D illustrates the image of parallel (side-by-side), Fig. 4 E illustrate by image and Fig. 4 F frame by frame image is shown.In other words, format conversion unit 310 produces these images.
Fig. 5 illustrates the flow chart of video format transform method according to an exemplary embodiment of the present invention.In operation S510, multidimensional image is received.In the present embodiment, stereo-picture is received.Thereafter, in operation S520, the resolution of the multidimensional image that receives is increased in proportion or is reduced.For the resolution of transforming multidimensional image, horizontal resolution can be transformed with different ratios with vertical resolution, and the image of multidimensional can be scaled with different ratios.If stereo-picture is received, then left image can be output through right output end of image mouth, and right image can be output through left output end of image mouth.
Then, in operation S530, be received about the characteristic information of display unit.About the example of the characteristic information of display unit comprise resolution, about the frequency of input signal, about information of the form of image or the like.Characteristic information about display unit can be received through DDC, DDC2 or DDC2B.At last, in operation S540, the form of the multidimensional image that receives is transformed to be consistent with the characteristic of display unit.More particularly, characteristic information about display unit is received, the multidimensional image that receives is transformed into the image with at least a form, selected from the form that produces by the accessible form of display unit, this multidimensional image is transformed into display unit acceptable image signal, and this picture signal is output to display unit.Because display unit receives the signal that is consistent with the VESA standard usually, so display unit output has the signal of VESA form.
As mentioned above, in the present invention, the form of 3-D view or stereo-picture is transformed being consistent with the characteristic of display unit, thereby this 3-D view or stereo-picture can easily be shown by the display unit of any kind.
The method of the form of transforming multidimensional image can be written as computer program.Forming the code and the code segment of computer program can easily be understood by those skilled in the art in the invention.In addition, this computer program is stored in the computer-readable medium, and reads and carry out to realize this transform method by computer.The example of computer readable recording medium storing program for performing comprises magnetic storage media, optical record medium and carrier media.
