Embodiment 1

[0025] This embodiment provides a split-screen image display method. The split-screen image display method is used in split-screen display, that is, images from different signal sources are simultaneously displayed in different display areas on one display. The display is at least capable of displaying 3D images. The executor of this embodiment is a split-screen image display device, and the split-screen image display device may be various terminals, such as medical equipment, computers, IPads, mobile terminals, and the like.

[0026] The split-screen image display method in this embodiment is based on the shutter-type 3D technology for display. The 3D glasses based on the shutter 3D technology mainly realize the 3D effect by increasing the fast refresh rate of the picture (usually up to 120Hz), which belongs to the active 3D technology, and is also called time-sharing shading technology or liquid crystal time-sharing technology. Specifically, when the 3D signal is input to t...

Embodiment 2

[0046] In this embodiment, a further supplementary explanation is given for the split-screen image display method in Embodiment 1. In this embodiment, the original signals of different signal sources need to be processed first, and then the first left-eye image data, the first right-eye image data, the second left-eye image data and the second right-eye image data are generated, according to the first left-eye image data generating a left-eye image signal from the image data and the second left-eye image data, generating a right-eye image signal from the first right-eye image data and the second right-eye image data, and alternately displaying the left-eye image signal on the display based on a shutter type 3D technology and the right-eye image signal.

[0047] Such as figure 2 As shown in FIG. 2 , it is a schematic flowchart of a split-screen image display method according to this embodiment. The flow display method of this embodiment includes:

Embodiment 3

[0071] In this embodiment, a four-channel split-screen display is taken as an example for specific description. That is, one display is divided into four display areas, and images from four signal sources are displayed respectively, and each image occupies a quarter of the display area. The resolution of the display is X*Y, where X is the number of effective pixels in each line of the display, and Y is the number of effective image lines contained in one frame of image.

[0072] Such as Figure 3A As shown, it is assumed that channels A, B, C, and D correspond to different signal sources, the image resolution of the signals of each channel is X*Y, and the signal refresh frequency is 60Hz. Among them, the signal sources corresponding to channels A and D send 2D signals, and the corresponding images are A and D respectively, and the signal sources corresponding to channels B and C send 3D signals. Specifically, the 3D signal format of channel B is The side-by-side (SBS, left a...

Abstract

The invention provides a split screen image display method and a device, and the method comprises the steps: a first signal in 2D format sent by a first signal source and a second signal in 3D format sent by the second signal source; a first left eye image data and a first right image data are generated based on the first signal, and the first left eye image data and the first right image data are the same; a second left eye image data and a second right image data are generated based on a second signal; a left eye image signal is generated according to the first left eye image data and the second left eye image data, a right eye image signal is generated according to the first right eye image data and the second right eye image data, and the left eye image signal and the right eye image signal are displayed alternately on a display based on a shutter 3D technology. According to the invention, the method and the device can make the user to normally watch an image corresponding to the first signal in original 2D format and an image corresponding to the second signal in original 3D format in split screen state without taking off 3D glasses.

Description

technical field [0001] The present invention relates to image display technology, in particular to a split-screen image display method and device. Background technique [0002] With the development and popularization of the Internet audio-visual industry, 3D stereoscopic display can bring audiences a greater sense of reality and on-site experience than traditional 2D display, and can completely substitute human eyes, ears and even thoughts into a virtual world, not only It can enable the audience to obtain the greatest spiritual and ideological relaxation, and can also reflect different lifestyles, which makes the application of 3D more and more extensive. Among them, the basic principle of 3D display technology is: the human left eye and right eye have a displacement of 5-6.5cm in the horizontal direction, so there is a certain distance between the images seen by the left and right eyes corresponding to the same point on the actual object. Therefore, using the parallax pri...
