Fig. 8 and Fig. 9 represent respectively identical view data respectively through and through image display system 10 handle amplification that the back produced image section.More particularly, Fig. 8 represent without image display system 10 handle and the amplification that produces image section 64.As shown in Figure 8, the image section 64 that has amplified presents pixelation, and the pixel that is separated from each other for example, constitutes and/or delineates the pixel of publishing picture as letter in the part 64 and be easy to see.

But as shown in Figure 9, enlarged image part 66 is to handle and produce through image display system 10.As shown in Figure 9, compare with the image section 64 that is exaggerated among Fig. 8, the image section 66 that has amplified does not show pixelation.Like this, through the processing of image display system 10, the picture quality of having amplified image section 66 has improved.More particularly, compare with the image section 64 that is exaggerated exactly, the resolution of the image section 66 that has amplified has been improved or has been improved.

In an illustrative embodiment, enlarged image part 66 is handled the back through four positions and produced, and is as described above, comprises first subframe, second subframe, the 3rd subframe and the 4th subframe.So, compare with the figure part 64 employed image data amounts that establishment has been amplified, create enlarged image part 66 and used four times pixel data amount.Therefore, through handling four positions, the resolution of enlarged image part 66 has increased twice or four square root with respect to the resolution of the image 64 that has amplified.So four positions are handled and made view data 16 have the resolution of 26 4 times of display devices when being shown, because after the pixel of each bar coordinate axis (x and y) doubles, the number of pixel is increased to original four times.

By a plurality of image subframes 30 of definition picture frame 28, and when displays image sub-frames 30, make being presented on the room and time of each subframe stagger mutually, image display system 10 can produce resolution will be greater than the display image 14 of display device 26.For example, in an illustrative embodiment, view data 16 has the resolution of 800 * 600 pixels, the resolution of display device is 800 * 600 pixels, handle four positions through image display system 10, the resolution of view data 16 is adjusted, and the resolution of the display image 14 that is produced reaches 1600 * 1200 pixels.Although therefore use the view data of low resolution and the display device of low resolution, image display system 10 can also produce the display image with high-resolution.In another illustrative embodiment, for example, view data 16 has the resolution of 1600 * 1200 pixels, the resolution of display device 26 is 800 * 600 pixels, when view data 16 not being carried out the resolution adjustment via the four positions processing of image processing system 10, the resolution of the display image 14 that is produced is 1600 * 1200 pixels.Thus, use the view data of high-resolution and the display device of low resolution, image display system 10 also can produce the display image of high-resolution.And, overlapping through image subframes 30 pixel each other, on time and space, stagger mutually each other when allowing displays image sub-frames 30 simultaneously, effect that image display system 10 can reduce is so-called " sieve door (screen-door) ", this effect be by as in the optical modulator between the adjacent micro-mirror device space produced.

By view data 16 buffer memorys can be produced picture frame 28, and the frame rate of the timing that disconnects view data 16 and display device 26 get in touch all subframes 30 of disposable displayed map picture frame 28.The display image 14 that resolution that image display system 10 can produce entire image has been enhanced.And, use resolution to be equal to or greater than the view data of display device 26 resolution, image display system 10 can produce the display image 14 of resolution greater than display device 26.In order to produce the display image 14 of resolution greater than display device 26, data that can resolution is bigger are as raw image data, or are synthesized from raw image data by image display system 10 and are input to image display system 10.Alternatively, can also be with the data delivery of low resolution to image display system 10 and be used for producing the display image 14 of resolution greater than display device 26.Use the data of low resolution to send image, can also show described data with higher resolution simultaneously with lower data rate.Thereby, use lower data rate can select the lower data-interface of speed for use, its possibility of result makes the electromagnetic interference (EMI) radiation also less.
