Background

The 3D image is one of the hottest technologies in the video industry, and the technology change from the flat display to the 3D display is promoted. The 3D display technology is a key part in the 3D image industry, and is mainly classified into two types, namely, glasses type 3D display technology and naked eye type 3D display technology. The naked-eye 3D display technology is a technology in which a user can view a 3D display screen without wearing glasses. Compared with glasses type 3D display, naked eye type 3D display belongs to free 3D display technology, and restraint on a user is reduced.

The naked-eye 3D display is based on a viewpoint, and recently, multi-viewpoint naked-eye 3D display has been proposed, so that a sequence of parallax images (frames) is formed at different positions in a space, so that a pair of 3D images having a parallax relationship can enter left and right eyes of a person, respectively, thereby giving a 3D feeling to a user. For a conventional multi-view naked eye three-dimensional (3D) display screen having, for example, N views, multiple views of space need to be projected with multiple independent pixels on the display panel.

However, in the conventional naked-eye 3D display screen configuration, only the raster is disposed on one side or both sides of the 2D display panel to provide a 3D display effect, and transmission and display of a 3D image or video are based on the 2D display panel. This presents the dilemma of resolution degradation and a surge in rendering computation. Meanwhile, the thickness of the display panel is increased, and particularly, the thickness of the display panel is increased for large-size display panels, so that the overall quality of the panel is increased, and the problems of installation and transportation during use are solved.

This background is only for convenience in understanding the relevant art in this field and is not to be taken as an admission of prior art.

With continued reference to fig. 1A, the naked eye 3D display terminal 1000 may further comprise a processor 101 communicatively connected to the at least one 3D processing device 130 via a video signal interface 140. In some embodiments illustrated herein, the processor 101 is included in or as a processor unit of a computer or smart terminal, such as a mobile terminal. It is contemplated that in some embodiments, the processor 101 may be disposed outside the naked-eye 3D display terminal, for example, the naked-eye 3D display terminal may be a multi-view naked-eye 3D display screen with a 3D processing device, such as a non-intelligent naked-eye 3D television.

For simplicity, the exemplary embodiments of the naked eye 3D display terminal hereinafter internally include a processor. Further, the video signal interface 140 is configured as an internal interface connecting the processor 101 and the 3D processing device 130, and the configuration can be more clearly understood with reference to the naked-eye 3D display terminal 200 implemented in a mobile terminal as shown in fig. 2 and 3. In some embodiments of the present invention, the video signal interface 140, which is an internal interface of the naked-eye 3D Display terminal 200, may be a MIPI, mini-MIPI, LVDS, min-LVDS, or Display Port interface.

The registers 122 may be used to temporarily store instructions, data, and addresses.

In some embodiments, the naked eye 3D display terminal 1000 may further comprise an eye tracking device or eye tracking data interface for acquiring real-time eye tracking data, such that the 3D processing device 130 may render respective sub-pixels of the composite pixel (composite sub-pixel) based on the eye tracking data. For example, in the embodiment shown in fig. 1B, the naked eye 3D display terminal 1000 further includes an eyeball tracking device 150 communicatively connected to the 3D processing device 130, so that the 3D processing device 130 can directly receive the eyeball tracking data. In the embodiment shown in fig. 1C, the eye tracking device (not shown) may for example be directly connected to the processor 101, while the 3D processing device 130 obtains eye tracking data from the processor 101 via the eye tracking data interface 151. In other embodiments, the eye tracking device may be connected to both the processor and the 3D processing device, which may enable the 3D processing device 130 to obtain the eye tracking data directly from the eye tracking device on the one hand, and enable other information obtained by the eye tracking device to be processed by the processor on the other hand.

With combined reference to fig. 1A-C and 5A-E, the transmission and display of 3D video signals within a naked eye 3D display terminal of some embodiments of the present invention is described. In the illustrated embodiment, the display screen 110 may define 6 viewpoints V1-V6, at which the user's eyes can see the display of corresponding ones of the composite sub-pixels of each composite pixel in the display panel of the multi-viewpoint naked-eye 3D display screen 110. Two different images seen by the two eyes of the user at different viewpoints form parallax, and a 3D image is synthesized in the brain.

In some embodiments of the present invention, the 3D processing device 130 receives video frames, e.g. as decompressed 3D video signals, from the processor 101 through the video signal interface 140, e.g. as an internal interface. Each video frame may comprise or consist of two images with a resolution of m × n or a composite image with a resolution of 2m × n or m × 2 n.

In some embodiments, the two images or composite image may include different types of images and may be in various arrangements.

As shown in fig. 5A, a video frame of a 3D video signal comprises or consists of two images 501, 502 with m × n resolution in a parallel format. In some embodiments, the two images may be a left eye parallax image and a right eye parallax image, respectively. In some embodiments, the two images may be a rendered color image and a depth image, respectively.

As shown in fig. 5B, a video frame of the 3D video signal contains or consists of two images 503, 504 with m × n resolution in a top-bottom format. In some embodiments, the two images may be a left eye parallax image and a right eye parallax image, respectively. In some embodiments, the two images may be a rendered color image and a depth image, respectively.

As shown in fig. 5C, the video frame of the 3D video signal contains a composite image 505 having a resolution of 2m × n in a left-right interleaved format. In some embodiments, the composite image may be left-and right-eye parallax composite images interleaved left and right, left-and right-interleaved rendered color and depth composite images.

As shown in fig. 5D, the video frame of the 3D video signal contains a composite image 506 having a resolution of m × 2n in a top-bottom interleaved format. In some embodiments, the composite image may be a left-eye and right-eye parallax composite image interleaved up and down. In some embodiments, the composite image may be an up-down interleaved composite image that renders color and depth.

As shown in fig. 5E, the video frame of the 3D video signal contains a composite image 507 having a 2m × n resolution in a checkerboard format. In some embodiments, the composite image may be a checkerboard format of left and right eye parallax composite images. In some embodiments, the composite image may be a checkerboard format of the rendered color image and the depth image.

It will be appreciated by those skilled in the art that the embodiments shown in the figures are merely schematic, and that the two images or composite image comprised by the video frames of the 3D video signal may comprise other types of images and may be in other arrangements, which fall within the scope of the invention.

In some embodiments, the resolution of m × n may be a resolution above Full High Definition (FHD), including, but not limited to, 1920 × 1080, 1920 × 1200, 2048 × 1280, 2560 × 1440, 3840 × 2160, and the like.

In some embodiments, the at least one 3D processing device 130, upon receiving a video frame comprising two images, renders at least one sub-pixel in each composite sub-pixel based on one of the two images and at least another sub-pixel in each composite sub-pixel based on the other of the two images. Similarly, in some embodiments, the at least one 3D processing device, upon receiving the video frame comprising the composite image, renders at least two of each of the composite sub-pixels based on the composite image. For example, at least one sub-pixel is rendered from a first image (portion) of the composite image and at least another sub-pixel is rendered from a second image (portion).

In some embodiments, this is dynamically rendered, for example, based on eye tracking data.

By way of explanation and not limitation, since the 3D processing device 130 in the embodiment of the present invention receives two images included in video frame data through the video signal interface 140 configured as an internal interface, for example, the resolution of each image (or half of the resolution of the composite image) corresponds to a composite pixel divided by a viewpoint (which includes a composite sub-pixel divided by a viewpoint). On one hand, as the viewpoint information is irrelevant to the transmission process, naked eye 3D display with small processing calculation amount and no loss of resolution can be realized; on the other hand, since the composite pixels (composite sub-pixels) are arranged corresponding to the viewpoints, rendering of the display screen can be realized in a point-to-point manner, and the amount of calculation is greatly reduced. In contrast, the transmission and display of images or videos of a conventional naked-eye 3D display screen are still based on a 2D display panel, and not only the problems of reduced resolution and greatly increased amount of rendering calculation, but also the problems of multiple format adjustment and image or video display adaptation may exist.

In some embodiments, the register 122 of the processor 101 may be configured to receive information about the display requirements of the multi-view naked eye 3D display screen 110, typically information independent of i views and related to the m × n resolution of the multi-view naked eye 3D display screen 110, so that the processor 101 sends video frames of the 3D video signal to the multi-view naked eye 3D display screen 110 that meet its display requirements. This information may be, for example, a data packet used to initially establish the video transmission.

Therefore, the processor 101 does not need to consider information related to i viewpoints of the multi-viewpoint naked eye 3D display screen 110 (i ≧ 3) when transmitting video frames of the 3D video signal. Instead, the processor 101 is able to transmit the video frames of the 3D video signal meeting its requirements to the multi-view naked eye 3D display screen 110 by means of the information related to the m × n resolution of the multi-view naked eye 3D display screen 100 received by the register 122.

In some embodiments, the 3D processing device 130 is further configured to perform shift rendering on the sub-pixels in the composite pixel according to the viewpoint position corresponding to the currently rendered sub-pixel and the next viewpoint position corresponding to the sub-pixel rendered in the next frame.

In some embodiments, the naked eye 3D display terminal 1000 may further include a codec configured to decompress and codec the compressed 3D video signal and transmit the decompressed 3D video signal to the at least one 3D processing device 130 via the video signal interface 140.

In some embodiments, the processor 101 of the naked eye 3D display terminal 1000 reads a video frame of the 3D video signal from the memory or from outside the naked eye 3D display terminal 1000, for example, through an external interface, and then transmits the read or received video frame of the 3D video signal to the at least one 3D processing device 130 via the video signal interface 140.

In some embodiments, the naked eye 3D display terminal 1000 further comprises a formatter (not shown), for example integrated in the processor 101, configured as a codec or as part of a GPU, for pre-processing the video frames of the 3D video signal such that they contain two images with a resolution of m × n or such that they contain a composite image with a resolution of 2m × n or m × 2 n.
