Description
Technical field
The invention belongs to the Display Technique field, relate in particular to the operation method of a kind of 3D (three-dimensional 3-D graphic) picture format and the television set that adopts this method.
Background technology
Along with the development of flat panel display, the 3D television set also will become an important directions of TV tech development gradually.The principle of 3D is that the content that spectators' right and left eyes is seen is different, what the left eye eyeball was seen is the image (to call left-eye image in the following text) of corresponding left eye, what right eye was seen is the image (to call eye image in the following text) of corresponding right eye, such two eyes have just had parallax, owing to the existence of parallax, in people's brain, will form the illusion of a solid.
If also seen eye image when spectators' left eye is seen left-eye image, also seen left-eye image when perhaps right eye is seen eye image, will in its brain, form the ghost image of image like this, this phenomenon is called as Crosstalk (crosstalking).
The reason that produces Crosstalk has two kinds, first kind is because the optics reason, in theory when showing left-eye image on the display screen of television set, spectators have only left eye can receive the light (as when the viewers wear anaglyph spectacles, the left eyeglass lens that has only the luminous energy of left-eye image to see through anaglyph spectacles enters spectators' left eye) of left-eye image.But in fact, may be because the right eye eyeglass of three-dimensional eyes turn-off fully, spectators' right eye also might receive the light of left-eye image.In like manner, spectators' left eye also may receive the light of eye image.
The second kind of reason that produces Crosstalk is exactly because the reason of processing television signals, at present the main flow form of 3D information source has: left and right sides form, form, level interweave and the vertical form etc. that interweaves up and down, and the resolution of various form 3D information sources have again a variety of, such as: 480P, 576P, 720P, 1080P etc.And the resolution of the display screen of main flow is 1920X1080 at present, so, handle so need carry out Scaling (computing) to picture signal by the Scaler (arithmetic element) of television set in order to allow the signal that is lower than 1080P resolution be presented on the display screen of 1080P.Existing Scaling method is normally carried out according to the correlation of neighbor.For example,, make its signal that becomes 1080P, the Crosstalk phenomenon of bringing owing to signal processing will occur if the 3D signal that input signal is the 480P level to interweave adopts existing method to carry out Scaling and handles.
