220. Processing the image to be displayed to obtain different partial images;
the acquired image to be displayed is a two-dimensional image and needs to be processed to obtain a hologram, wherein the processing can be to obtain a computed hologram by encoding with a manual method. The step of producing the computer generated hologram may comprise: sampling, calculating, encoding, rendering and reducing and reproducing, for example, first calculating a mathematical function of the image to be displayed, sampling the mathematical function to obtain a distribution of discrete points; then, performing discrete Fourier transform to obtain a discrete Fourier transform spectrum; and then encoding (i.e. the process of converting the two-dimensional light length complex amplitude distribution into the two-dimensional transmittance function distribution of the hologram) to obtain a holographic transmittance function, and drawing and reducing to finally obtain a computed hologram.
After processing to obtain the hologram, the hologram is divided by image processing to obtain different partial images to be distributed to four micro projectors.
230. Transmitting the different partial images to the four pico projectors, respectively;
in the last step, different partial images are obtained, and after the four different partial images are obtained, the four different partial images are respectively transmitted to four micro projectors; different partial images are obtained, or two or three different partial images may be obtained, and then after the different partial images are obtained, the two or three different partial images are transmitted to two or three micro projectors, and the transmission of the two or three different partial images and the transmission of the four micro projectors may be randomly allocated, and of course, in some other embodiments, before the different partial images are respectively transmitted to the four micro projectors, the method may further include: and acquiring a gaze focus of a user, and transmitting a front partial image of a display object of an image to be displayed to the gaze focus.

The folding can be realized by folding the four micro projectors towards the center of the foldable screen by a certain angle, or folding the four micro projectors towards the back of the foldable screen by a certain angle. The "certain angle" may be 0 to 180 °, as long as the projection surfaces of the four micro projectors form a rectangular pyramid and are combined into a 3D display effect (as shown in fig. 2 a). The folding can also be realized by folding four micro projectors towards the center of the foldable screen by different angles, so that the position of the holographic image generated by projection can be changed along with the change of the folding angle, and only the projection surfaces of the four micro projectors can form a rectangular pyramid and are combined into a 3D display effect.
In some embodiments, the four micro projectors are controlled to be folded, and the four micro projectors can be also folded by arranging a motor below the positions of the four micro projectors in the foldable screen to control the motor to rotate to fold the foldable screen.
In some embodiments, the "folding" may also be manually performed by a user to freely adjust the angles of the four micro-projectors, so as to obtain the best matching effect among the four micro-projectors 120.
In this embodiment, the method obtains the image to be displayed, processes the image to be displayed to obtain different partial images, respectively transmits the different partial images to the four micro projectors, and controls the four micro projectors to turn over, so as to generate and display the holographic image by projection. Through the mode, combine collapsible screen and holographic image, make people's information interaction mode novel abundanter, bring brand-new user experience.
In some embodiments, prior to step 230, the method 200 further comprises: and carrying out edge fusion processing on the partial image. In order to solve the problem of physical gaps at the image splicing position during holographic display, seamless splicing and edge fusion processing needs to be carried out between channels, and a complete holographic display scene picture is realized. After the image to be displayed is obtained, the image to be displayed is processed to obtain different partial images, and then edge fusion processing is carried out on the partial images. The specific implementation of the edge fusion processing may be: as shown in fig. 2b, assuming that four different partial images are obtained, the pixels of the four different partial images are 1280 × 1024, first, the four different partial images are transversely spliced, and 128 pixels are selected in the overlapping area to form a whole screen 4352 × 1024; then, multiplying each pixel of the image of the superposed part by a fusion function, selecting a cosine function curve as an initial fusion curve, and processing to obtain a synthetic image; and finally, adjusting the brightness of the composite image, and then performing image segmentation processing to obtain four partial images subjected to edge fusion processing.
In some embodiments, the step 240 may include:
241. sending a control instruction through a bus connected with the micro projector;
242. and controlling the four micro projectors to turn over towards the center of the foldable screen according to the control instruction.
When a user sends a control instruction, the smart phone transmits the control instruction to the bus, and controls the four micro projectors to turn over towards the center of the foldable screen. The bus is connected with the micro projector and the foldable screen and used for transmitting instructions sent by a user.
