Embodiment 1

[0061] see figure 1 , is a schematic flow chart of an image display method according to an embodiment of the present application, including:

[0062] Step 101, in response to an image display instruction, acquire an image to be displayed and convert it into a grayscale image.

[0063] Specifically, the image is the display screen of the mobile terminal, including Apps that may be used by various users, Android system interfaces, etc., especially the interfaces of many reading Apps. For example, under the Reading App, the displayed image content is generally text. Image or non-text image, non-text image means that the display content in the image includes pictures, often containing richer pixels of various gray values. A text image means that the display content in the image is text without pictures, and the grayscale pixel values ​​​​often contain only a few grayscales between 0-255, and the distribution is often discontinuous. When the user uses the mobile terminal, the col...

Embodiment approach

[0096] As an optional implementation, the method also includes:

[0097] Start the reading application, and judge whether the identification of the reading application is in the preset list;

[0098] When the application program is not in the preset list, when the image to be displayed is acquired, output and display the image to be displayed;

[0099] Wherein, when the application program is in the preset list and the image to be displayed is acquired, the first image feature of the grayscale image is input into the classification model.

[0100] The identifier of the reading application may be, but not limited to, the name of the application package of the currently running application. In addition, a preset list is preset in this application, and the preset list includes the name of the application package of the reading application. If it is detected that the name of the application package of the currently running application is in the preset list, the image to be displa...

Embodiment 2

[0127] Based on the same inventive concept, the present application also provides an image display device, such as Figure 5 As shown, the device includes:

[0128] An image acquisition module 501, configured to acquire an image to be displayed and convert it into a grayscale image in response to an image display instruction;

[0129] An image model first prediction module 502, configured to input the first image features of the grayscale image into a classification model, and the classification model is used to predict whether the grayscale image is a text image or a non-text image according to the input first image features image model;

[0130] The first contrast enhancement module 503 is configured to enhance the contrast of the image and display it when it is determined that the grayscale image is a text image according to the prediction result of the classification model;

[0131] The second image model prediction module 504, configured to match the second image featur...

Abstract

The invention discloses an image display method and device and electronic equipment, and the method comprises the steps of obtaining a to-be-displayed image in response to an image display instruction, and converting the to-be-displayed image into a grayscale image; inputting the first image feature of the grayscale image into a classification model, wherein the classification model is used for predicting whether the grayscale image is a text image or a non-text image according to the input first image feature; when it is determined that the grayscale image is a text image according to the prediction result of the classification model, increasing the contrast ratio of the image and displaying same; when it is determined that a classification result predicted by the classification model is a non-text image, matching a second image feature of the grayscale image with at least one preset text image feature template one by one; and when the successfully matched text image feature template exists, improving the contrast ratio of the image and displaying the image. The text image can be identified more accurately, and pocking marks caused by a jitter point algorithm are eliminated.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image display method and device, and electronic equipment. Background technique [0002] The ink screen has the characteristics of eye protection and low power consumption, which is very suitable for users who like to read e-books. The display modes of the ink screen include 2 gray scales, 4 gray scales, 16 gray scales, etc. In the display modes of 4 gray scales and 16 gray scales, although the display effect is good, due to the slow refresh, it causes serious flickering during refresh, and due to the low frame rate, the frustrating feeling is obvious when sliding. In the 2-grayscale display mode, each pixel has only two colors of pure black and pure white, without intermediate gray, and the refresh frame rate is relatively high, up to 6-7fps, which is suitable for sliding operations such as browsing the web. [0003] At present, in the 2-gray-scale display mode (sm...
