Description
Technical field
The image chip that the present invention relates to a kind of resolution contraction and enlargement rate method and have the resolution contraction and enlargement rate function.
Background technology
Spatial multiplexing method (spatial-multiplexed) is a kind of common 3D rendering treatment technology, the principle of the method is to be the left eye and the picture signal of right eye are mixed in regular turn to form the 3D rendering signal, it is that the picture signal that will be positioned at odd positions is set at the picture signal that left eye receives, and the picture signal that is positioned at the even number position is set at the picture signal that right eye receives.Since about two receive different picture signals, under the effect of staggered imaging, can produce the visual effect of 3D.
When the 3D rendering signal is transferred into display screen, often need to carry out earlier convergent-divergent, to cooperate the set resolution of display screen.In the existing practice, when carrying out the convergent-divergent operation, be directly the 3D rendering signal to be done a certain proportion of convergent-divergent according to original putting in order, so will destroy " picture signal that is positioned at odd positions is the picture signal that left eye received; and the picture signal that is positioned at the even number position is the picture signal that right eye received " and this principle, so that during the 3D rendering signal of human eye after receiving convergent-divergent, can produce wrong image, and can't obtain due 3D visual effect.
Fig. 1 represents to use prior art to amplify the schematic diagram of 3D rendering signal 11.As shown in the figure, in 3D rendering signal 11, picture signal L1, the L3, the L5 that are positioned at the 1st, 3,5 positions are set at the picture signal that left eye receives, and picture signal R0, the R2, the R4 that are positioned at the 0th, 2,4 positions are set at the picture signal that right eye receives.
As shown in the figure, through resulting 3D rendering signal 12 after amplifying 2 times, and do not meet due putting in order, wherein, the picture signal that is positioned at the 1st, 3,5,7,9,11 positions is respectively R0, L1, R2, L3, R4, L5, since the picture signal of odd positions be set to left eye the picture signal that should receive, so left eye can receive picture signal R0, L1, R2, L3, R4, L5.In like manner, right eye can receive picture signal R0, L1, R2, L3, R4, the L5 of even number position.
So, about two meetings receive identical picture signal so that can't produce the visual effect of 3D.More and, about two this moment being seen general image be entanglement.
Summary of the invention
In view of this, the invention provides a kind of image chip with resolution contraction and enlargement rate function, in order to handle a 3D rendering signal, this 3D rendering signal is by a plurality of first picture signals and the interconnected in regular turn mixing of a plurality of second picture signal, wherein this 3D rendering signal can be transferred into a display screen to present three-dimensional image effect, this image chip comprises: a receiving element, in order to receive this 3D rendering signal; One separative element is respectively by isolating described first picture signal and described second picture signal in this 3D rendering signal; One unit for scaling is according to a both certainty ratio, in order to described first picture signal and described second picture signal are scaled a plurality of first target image signals and a plurality of second target image signal respectively; An and mixed cell, according to a both definite sequence, in order to the interconnected described first target image signal and the described second target image signal to blend a target 3D rendering signal, and when this target 3D rendering signal is transferred into this display screen, can present according to the three-dimensional image effect behind this set proportional zoom.
The present invention more provides a kind of resolution contraction and enlargement rate method, in order to handle a 3D rendering signal, this 3D rendering signal is by a plurality of first picture signals and the interconnected in regular turn mixing of a plurality of second picture signal, wherein this 3D rendering signal can be used to present three-dimensional image effect, and this method may further comprise the steps: receive this 3D rendering signal; Respectively by isolating described first picture signal and described second picture signal in this 3D rendering signal; According to a both certainty ratio, described first picture signal and described second picture signal are scaled a plurality of first target image signals and a plurality of second target image signal respectively; And according to a both definite sequence, interconnected described first target image signal and the described second target image signal are blending a target 3D rendering signal, and this target 3D rendering signal can be used to present the three-dimensional image effect according to behind this set proportional zoom.
