Abstract

The method is used for processing a 3D image signal. The 3d image signal is obtained by sequentially interlacing multi first image signals and multi second image signals, and then is transmitted to a display screen for displaying. The image chip comprises: a receiving unit for receiving 3D image signal; a separating unit for separating first image signals and second image signals from the 3D image signal; a scaling unit for scaling the first image signals and the second image signals into the first target image signals and the second target signals; a mixing unit for sequentially interlacing the first target image signals and the second target signals in order to create a 3D image signal, and transmits the 3D signal to the display screen.

Description

technical field

[0001] The invention relates to a resolution scaling method and an image chip with the resolution scaling function. Background technique

[0002] Spatial multiplexing (spatial-multiplexed) is a common 3D image processing technology. The principle of this method is to sequentially mix the image signals of the left eye and the right eye to form a 3D image signal. The image signal at the position is set as the image signal received by the left eye, and the image signal at the even position is set as the image signal received by the right eye. Since the left and right eyes receive different image signals, a 3D visual effect will be produced under the effect of interlaced images.

[0003] When the 3D image signal is transmitted to the display screen, scaling is often required first to match the predetermined resolution of the display screen. In the existing practice, when the scaling operation is performed, the 3D image signals are directly scaled according to t...

Embodiment Construction

[0022] The main spirit of the present invention is, before scaling the 3D image signal, first separate the first image signal related to the left eye and the second image signal related to the right eye from the 3D image signal, and then scale the first image signal respectively and the second image signal, and finally mix the scaled first image signal and the second image signal to form a new 3D image signal, so as to achieve the effect of scaling a 3D image.
