And finally, transmitting the target image signal to a display screen for display. Therefore, compared with the superimposed image obtained by superimposing and calling the original image at the GPU of the graphic processor of the electronic device in the prior art, the superimposed image obtained by superimposing and calling the original image at the display screen end of the electronic device can be displayed on the display screen simultaneously on the basis of not changing the original image, and further the target images displayed by the display screen are all displayed as paper image effects, so that the technical problem of higher limitation of the paper image effects displayed by the display screen is solved.
Fig. 2 is a schematic flow chart of another image processing method provided in an embodiment of the present application, which is applied to an integrated circuit chip of a logic board, wherein the logic board includes an integrated circuit chip and a memory chip, and the logic board is connected to a display screen of an electronic device, and as shown in fig. 2, the method includes:
201. the superimposed image is stored in a memory chip of the electronic device, wherein the superimposed image includes a plurality of texture types.

For example, the integrated circuit chip may store a plurality of superimposed images in advance in a memory chip of the electronic device, where the superimposed images include a plurality of texture types, for example, the texture types include rice paper, wall surfaces, wood grains, and the like, and the superimposed images include texture pictures of any ultra-high definition 8K resolution (8K resolution) of rice paper, wall surfaces, wood grains, and the like. And the superimposed image is a transparent image containing textures, and after the superimposed image is superimposed on the original image, the paper image effect can be displayed on the display screen.

Generating correction data corresponding to each superimposed image according to the gray value corresponding to each texture type and the texture type included in each superimposed image, and storing the generated correction data in a memory chip; wherein the correction data is used to correct the gray value in the superimposed image.
For example, the integrated circuit chip may generate correction data corresponding to each superimposed image according to the gray value corresponding to each texture type and the texture type included in each superimposed image, and store the generated plurality of correction data in the memory chip, so as to facilitate the correction data to be invoked to correct the gray value in the superimposed image.
204. Receiving an original image signal transmitted by a signal main board in electronic equipment, wherein the original image signal comprises an original image to be displayed; the original image signal is received by the signal main board from other devices.
In one example, the original image includes one or more of the following: external input signals of a high definition multimedia interface HDMI, external input signals of a video image VGA, external input signals of a household video and audio equipment transmission port AV, external input signals of a television TV, an operating system desktop, an application APP interface and a system menu interface.
For example, the integrated circuit chip may receive an original image signal sent by a signal motherboard in the electronic device, where the original image signal includes an original image to be displayed, where the original image signal is received by the signal motherboard from another device, for example, the original image signal is an external input signal of the high-definition multimedia interface HDMI, or is an external input signal of the video image VGA, or is an external input signal of the transmission port AV of the home video and audio device, or is an external input signal of the television set TV, or is an operating system desktop, or is an application APP interface, or is a system menu interface.

205. And calling a pre-stored superimposed image from the memory chip, and superimposing the pre-stored superimposed image on the original image in the original image signal to obtain the target image.
Step 205 includes two implementations:
The first implementation of step 205: the superimposed image includes a plurality of texture types; if the received original image signal comprises a request for calling the superimposed image, wherein the request for calling the superimposed image is a request sent by a user to the electronic equipment, and the request for calling the superimposed image comprises a target texture type customized by the user, determining the target texture type contained in the request for calling the superimposed image, and calling a prestored superimposed image corresponding to the target texture type from a memory chip; and superposing the superposition image corresponding to the target texture type on the original image in the original image signal to obtain the target image.
The second implementation of step 205: the superimposed image includes a plurality of texture types; calling a pre-stored superimposed image with a preset texture type from a memory chip, and superimposing the superimposed image with the preset texture type on an original image in an original image signal to obtain a target image.
Illustratively, fig. 3 is a schematic flow chart of still another image processing method according to an embodiment of the present application, where, as can be seen from fig. 3, the "signal processing and outputting" module includes signal input, image scaling, color space conversion, and image processing, and the "signal processing and outputting" module represents a portion executed by the signal main board; the paper image processing module comprises a superposition image processing module, a specific GAMMA data calling module, an image signal output module, a Flash module and a T-CON IC module, wherein the paper image processing module represents the execution part of the integrated circuit chip; the third display screen display module is used for displaying the target image; the memory chip (T-CON Flash) has stored therein the superimposed image in advance. Therefore, the integrated circuit chip can directly call the pre-stored superimposed image from the memory chip and superimpose the pre-stored superimposed image on the original image in the original image signal to obtain the target image. In the process of calling the superimposed image, the calling mode of calling the prestored superimposed image by the integrated circuit chip comprises a manual calling mode and a default calling mode.
For example, in a first implementation, the calling mode for calling the pre-stored overlay image is a manual calling mode, and the overlay image includes a plurality of texture types. In the process of displaying an original image on a display screen, a user sends a superimposed image calling request to electronic equipment, the superimposed image calling request comprises a target texture type customized by the user, a signal main board in the electronic equipment receives the superimposed image calling request and sends the superimposed image calling request to an integrated circuit chip, the integrated circuit chip receives an original image signal sent by the signal main board and the superimposed image calling request carried in the original image signal, the target texture type contained in the superimposed image calling request is determined, a prestored superimposed image corresponding to the target texture type is called from a storage chip, and the superimposed image corresponding to the target texture type is superimposed on the original image in the original image signal, so that a target image is obtained.
Or in a second implementation, the calling mode for calling the pre-stored overlay image is a default calling mode, and the overlay image comprises a plurality of texture types. In a default call mode, if an original image signal sent by a signal main board is received, calling a pre-stored superimposed image of a preset texture type from a memory chip of the electronic device by default, and superimposing the superimposed image of the preset texture type on the original image in the original image signal to obtain a target image, wherein the superimposed image of the preset texture type can be preset by an integrated circuit chip or can be preset by a user and saved as a default call, so that the superimposed image of the preset texture type is called by default when the display screen is turned on next time.
206. A target image signal corresponding to the target image is generated.
Illustratively, the integrated circuit chip generates a target image signal corresponding to the target image, the target image signal including the target image.
207. And retrieving pre-stored correction data from the memory chip, correcting the gray value of the target image in the target image signal according to the correction data to obtain a corrected target image, and generating a corrected target image signal corresponding to the corrected target image.
In one example, where the overlay image includes a plurality of texture types, after determining the texture type of the retrieved overlay image, step 207 includes: retrieving pre-stored correction data corresponding to the texture type of the superimposed image from the memory chip, correcting the gray value of the target image in the target image signal according to the correction data corresponding to the texture type of the superimposed image, obtaining a corrected target image, and generating a corrected target image signal corresponding to the corrected target image.
Illustratively, since the superimposed image is a transparent and textured image, the resulting target image is also textured, which can result in a change in the gray value of the target image, e.g., the black font on the original image after the original image is superimposed with the superimposed image increases the gray value due to the texture superimposed, i.e., the gray value of the target image changes. Therefore, it is necessary to call pre-stored correction data from the memory chip, and perform correction processing on the gray value of the target image in the target image signal according to the correction data, to obtain a corrected target image, and further obtain a corrected target image signal.
For example, a plurality of correction data (i.e., GAMMA data) are stored in advance in the memory chip (T-CON Flash), and each correction data corresponds to an overlay picture of a texture type. After determining the texture type of the fetched superimposed image, the integrated circuit chip can fetch prestored correction data corresponding to the texture type of the superimposed image from a memory chip of the electronic device, and correct the gray value of the target image in the target image signal according to the correction data corresponding to the texture type of the superimposed image to obtain a corrected target image, thereby obtaining a corrected target image signal corresponding to the corrected target image.
208. And transmitting the target image signal to a display screen for display.
Illustratively, this step may refer to step 103 in fig. 1, which is not described herein.
In the embodiment of the application, the superimposed image is stored in a memory chip of the electronic device, wherein the superimposed image includes a plurality of texture types. A gray value corresponding to each texture type is determined. Generating correction data corresponding to each superimposed image according to the gray value corresponding to each texture type and the texture type included in each superimposed image, and storing the generated correction data in a memory chip; wherein the correction data is used to correct the gray value in the superimposed image. Receiving an original image signal transmitted by a signal main board in electronic equipment, wherein the original image signal comprises an original image to be displayed; the original image signal is received by the signal main board from other devices.
