[0080] In order to solve the problem that the existing zoomed-in image is unclear and distorted, which leads to low user satisfaction with the zoomed-in image, this embodiment provides a zoomed-in image processing method, such as image 3 as shown, image 3 The basic flow chart of the enlarged image processing provided in this embodiment, the enlarged image processing includes:

[0081] S301: Obtain abnormal pixels in the enlarged image.

[0082] In this embodiment, the original image is the image before the enlargement process, and the enlarged image is generated after the original image is enlarged. It is the quantification of the absorption characteristics of body organs (such as X-ray pictures), or the radar reflection cross section of a target object (radar image), or the temperature field of an area (infrared image), etc. For example, the resolution of the original image is 720×480, and when the original image is enlarged into an enlarged image with a resolution of 144...

[0102] In order to better understand the present invention, this embodiment provides a specific example for illustration, assuming that the abnormal pixels include white pixels, such as Figure 10 as shown, Figure 10 It is a detailed flowchart of the image magnification processing method provided in the second embodiment of the present invention, the image magnification processing method includes:

[0103] S1001. Obtain the gray scale value output by each pixel in the enlarged image.

[0104] In this embodiment, the zoomed-in image is a zoomed-in image, and there is no limitation on the zoom-in manner of the image.

[0105] S1002. Recognize pixels whose grayscale values ​​are within a preset range of grayscale values ​​as white pixels.

[0106] Wherein there are multiple gray scale values ​​within the preset gray scale value range, preferably, the preset gray scale value range includes gray scale values ​​of white, off-white, light gray, and gray in the gray scale levels

[0133] This embodiment also provides a terminal, see Figure 11 As shown, it includes a processor 1101, a memory 1102 and a communication bus 1103, wherein:

[0134] The communication bus 1103 is used to realize connection and communication between the processor 1101 and the memory 1102;

[0135] The processor 1101 is configured to execute one or more programs stored in the memory 1102, so as to implement the steps of the enlarged image processing method in the first embodiment and / or the second embodiment above.

[0136] This embodiment also provides a computer-readable storage medium, where one or more programs are stored in the computer-readable storage medium, and one or more programs can be executed by one or more processors, so as to implement the above-mentioned first embodiment and / or the steps of the enlarged image processing method in the second embodiment.

[0137] This embodiment also provides a method for processing an enlarged image, such as Figure 12 As sho...

Abstract

The invention discloses an amplification image processing method, a terminal and a computer readable storage medium. The method comprises the following steps of acquiring an abnormal pixel point in anamplification image; acquiring the pixel value of each pixel point in a first preset area adjacent to the abnormal pixel point in the amplification image; according to the pixel value of each pixel point in the first preset area, calculating and acquiring the target pixel value of the abnormal pixel point; and setting the target pixel value acquired through calculation to be the pixel value of the abnormal pixel point. In the invention through matching each abnormal pixel point in the amplification image with the adjacent pixel value of the abnormal pixel point, a problem that an existing amplification image is not clear so that the satisfaction degree of a user to the amplification image is not high is solved. The invention also discloses the terminal and the computer readable storage medium. Through implementing the above scheme, the definition of the amplification image is increased, and the satisfaction degree and the experience feeling of the user are guaranteed.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, to an enlarged image processing method, a terminal and a computer-readable storage medium. Background technique [0002] What we see and touch in real life are all concrete things. In order to record and express this information, people often use images as a means of expression. With the development of the data age, these images need to be input to the smart terminal, and stored and processed on the smart terminal. For example, in order to commemorate the beautiful moments in life, people often need to enlarge the image when the object is far away. However, the image is not clear after the enlarged image, because the enlarged image will have a lot of "out of nothing" pixels. These pixels The dots do not exist objectively, but the smart terminal thinks they "should exist" in order to enlarge the image, that is, the smart terminal supplements the pixels in the enlarge...
