Description

Distortion processing method and terminal

technical field

The present invention relates to the field of image processing, in particular to a distortion processing method and terminal.

Background technique

Many people have this problem when using a camera: images taken in a room with fluorescent lighting will appear greenish, images taken in a room with tungsten lighting will appear yellowish, and images taken in sunlight shaded areas will appear yellowish. blue. The reason is that the camera has no memory and adaptability. The color of the image it displays will change with the color temperature of the irradiated light. A piece of white paper is sometimes blue, sometimes red or yellow under different light. . Based on this, the white balance technology came into being, which can make the white image still white. They sense blue, green, and red light respectively. Under the preset condition, the electronic amplification ratio of these three photosensitive circuits is the same, which is a relationship of 1:1:1. The adjustment of white balance is to change according to the adjusted scene. this proportional relationship. For example, the ratio of blue, green, and red light of the scene to be adjusted is 2:1:1 (the ratio of blue light is high, and the color temperature is high), then the ratio of the adjusted white balance is 1:2:2, and the adjusted circuit In the magnification ratio, the proportion of obvious blue is reduced, and the proportion of green and red is increased, so that the adjusted scene passes through the white balance adjustment circuit to the captured image, and the proportion of blue, green and red will be the same. That is to say, if the adjusted white is a little blue, then the white balance adjustment will change the normal proportional relationship to weaken the magnification of the blue circuit, and at the same time increase the ratio of green and red, so that the resulting image is still white.

Under normal circumstances, the degree of distortion of the original image captured is affected by various factors such as light source, color temperature, focal length, etc. Even if the original image is subjected to white balance processing, some areas of the image after white balance processing still exist relatively severe distortion.

Example 1

As shown in FIG. 2, the figure shows a distortion processing method provided by an embodiment of the present invention. As can be seen from the figure, the method may include:

S210, control the first camera and the second camera to simultaneously shoot the shooting target, and generate the first target image and the second target image respectively;

Here, it should be noted that the first camera and the second camera are arranged on the same horizontal line on the same side of the terminal, and the distance between the first camera and the second camera is less than a preset distance threshold, the purpose of which is All the image features included in the generated first target image and the second target image are the same, for example, the image size, resolution, brightness, color and other features are the same.

S220, performing white balance processing on the first target image by using a white balance technology to generate a first white balance image corresponding to the first target image;

S230, obtaining the distortion area in the second target image;

S240, using the white balance technology to perform white balance processing on the distortion area to generate a second white balance image corresponding to the second target image;

Since the distortion degree of the captured original image is easily affected by various factors such as light source, color temperature, focal length, etc., the distortion degree of different areas in the original image is different. Therefore, it is possible to focus on white balance processing on areas with serious distortion in the image. It is understandable that when processing an image, it is usually necessary to consider all the image features contained in the image. Therefore, when performing white balance processing, white balance processing is performed on the entire image rather than white balance on a part of the image. Processing, the former considers more complex factors, the latter is targeted, and the image characteristics of the processing area are relatively simple, so the processing results of the latter will be better than the former, that is, local (targeted) white balance processing The effect is better than the overall (global) white balance processing effect.

S250. Perform image fusion processing on the first white balance image and the second white balance image to generate a third target image.

Understandably, image fusion refers to synthesizing favorable information from two or more source images in order to obtain a more accurate, comprehensive and reliable image description of the same scene and the same target. This technology makes full use of redundant information and complementary information in multiple images to be fused. It mainly includes pixel-level image fusion methods, feature-level image fusion methods, and decision-level image fusion methods. For the specific implementation steps of each method, due to It belongs to the prior art, so it is not repeated here.

In addition, it should be noted that the so-called white balance: refers to the process of image processing, the color restoration of the image of the original material is white, and the influence of the color temperature of the external light source is removed, so that it also appears white in the photo. That is to say, no matter under any light source, white objects can be restored to white. Common white balance algorithms include gray world method, standard deviation weighted gray world algorithm and total reflection algorithm, etc. Among them, the gray world method mainly adjusts the RGB mean value of the original image to R=G=B according to the gray world theory. However, the imperfection is that this algorithm is generally less sensitive to images that are not rich in color, so the processing effect will not be very satisfactory, and the limitations are very large; the standard deviation weighted gray world algorithm, this algorithm is an improvement for the above algorithm , its principle is to divide the image into several blocks, and then use statistics to analyze each block to see the richness of the color inside, the weight of the color is more, the weight of the color is reduced, and finally the sum is obtained to get a mean, according to this A relatively accurate value is used to correct the RGB value; the total reflection algorithm, the algorithm thinks that the brightest point is white, and if not, reverse correction is performed for the value deviating from white. The disadvantage is that there is no high point or the color of the image is complex, and its correction effect will be relatively weak. Since these algorithms belong to the prior art, the specific implementation steps of these algorithms will not be repeated here.

Exemplarily, for step S230, the acquiring the distortion area in the second target image may specifically include the following steps:

S2301a, traversing all pixel units in the second target image, when the pixel value corresponding to the pixel unit falls within a preset pixel value range, marking the pixel unit as a near-white unit;

S2302a, dividing the second target image according to a preset image dividing rule to obtain N image sub-regions;

Here, in order to reduce the complexity of implementing the technical solution, the second target image may be divided evenly and in equal proportions.

S2303a: Calculate the number of near-white cells included in each of the image sub-regions, and use the image sub-region containing the largest number of near-white cells as the distortion region in the second target image.

In order to solve the white drift phenomenon caused by different color temperatures, white is usually used as the base color for adjusting the color of the image. Therefore, the maximum pixel value and minimum pixel value similar to white can be preset here, and the pixel value in the second target image obtained by scanning the second target image is greater than or equal to the minimum pixel value and less than or equal to the minimum pixel value. The pixel unit of the maximum pixel value, and the pixel value of the second target image is greater than or equal to the minimum pixel value and is less than or equal to the maximum pixel value. The area where the pixel units are denser is set as a near-white area, That is, the distorted area in the second target image.

For step S230, the obtaining of the distorted region in the second target image may also be implemented in the following manner:

S2301b. Receive a touch operation for any position on the terminal display screen, and obtain position information of the touch operation on the terminal display screen;

S2302b, taking the position information of the touch operation on the display screen of the terminal as the center, determine the distortion area on the display screen of the terminal.

Specifically, for step S2302b, the determining the distortion area on the terminal display screen with the position information of the touch operation on the terminal display screen as the center may include: obtaining a preset radius parameter value; Taking the position information of the touch operation on the terminal display screen as the center, and using the radius parameter value as the radius, the distortion area on the terminal display screen is determined.

Since the human brain has memory and adaptability to the color of the image, that is to say, the user can directly identify whether the color of the captured image is distorted and which area in the captured image is more distorted through the eyes. Based on this, the distortion area can be independently selected and calibrated by the user, thereby facilitating the terminal to obtain the distortion area and subsequent white balance processing.

An embodiment of the present invention provides a distortion processing method. The method mainly performs overall white balance processing (ie, global white balance processing) on a first target image captured by a first camera; The areas with severe distortion in the target image are subjected to white balance processing (that is, local white balance processing), and the two white balance processed images are fused. Distortion problem.

Embodiment 2

In order to facilitate the understanding of the above technical solutions, as shown in FIG. 3 , a terminal with two cameras in the front or two cameras in the rear is taken as an example, and the diagram of a distortion processing method provided by an embodiment of the present invention is given. The preferred implementation process, as can be seen from the figure, specifically includes the following steps:

S310, the terminal controls the first camera and the second camera to shoot the shooting target at the same time, so as to generate the first target image and the second target image respectively;

Here, the first camera and the second camera are two cameras that are close side by side and are disposed on the same side of the terminal, such as two cameras at the front of the terminal or two cameras at the back of the terminal. Specifically, the first camera and the second camera may be arranged on the same horizontal line on the same side of the terminal, and the distance between the first camera and the second camera is less than a preset distance threshold, the purpose of which is to make the generated All the image features contained in the first target image and the second target image are the same, for example, the image size, resolution, brightness, color and other features are the same.

S320. The terminal performs white balance processing on the first target image by using a white balance technology to generate a first white balance image corresponding to the first target image;

S330. The terminal receives a touch operation for any position on the terminal display screen, and obtains position information of the touch operation on the terminal display screen;

S340. The terminal acquires a preset radius parameter value, and takes the position information of the touch operation on the terminal display screen as the center, and uses the radius parameter value as the radius to determine the value of the radius parameter on the terminal display screen. Distortion area;

S350, the terminal uses the white balance technology to perform white balance processing on the distortion area, to generate a second white balance image corresponding to the second target image;

S360. The terminal performs image fusion processing on the first white balance image and the second white balance image to generate a third target image.

For example, in a room full of incandescent lights, a user uses a mobile phone with dual cameras on the back to take a photo. After the user opens the camera application in the mobile phone, points to a shooting target in the room, and clicks on the camera application interface to take a photo key, at this time, the mobile phone uses the rear dual cameras to shoot the target at the same time, and generates two identical original images, namely the first target image and the second target image; then, the mobile phone uses the white balance technology to The first target image is subjected to white balance processing to generate a first white balance image corresponding to the first target image; at the same time, as shown in FIG. Prompt the user to calibrate the area that needs to be white balance processed. As can be seen from the figure, at this time, the user can calibrate the area that needs to be white balance processed by moving the white circle frame, and can also adjust the size of the white circle frame. The size of the calibration area; after the user calibrates the area that needs to be white-balanced on the second target image, as shown in Figure 5, the area in the white circle is the area that the user has calibrated that needs to be white-balanced, and the mobile phone detects the user The location area of the calibrated area in the second target image, and white balance processing is performed on the area corresponding to the location area in the second target image to obtain a second white balance image; further, the mobile phone uses an image fusion technology to The first white balance image and the second white balance image obtained after the white balance processing are fused to finally generate a third target image.

It can be seen from the preferred implementation process and specific examples of the above-mentioned distortion processing method that the method can perform overall white balance processing on the first target image captured by the first camera, and can also distort the second target image captured by the second camera. The more serious areas are subjected to white balance processing, and finally, the images that have been processed by the two white balance processing are fused to obtain a photo that is more satisfactory to the user. In this way, the problem of distortion in some areas after the overall white balance processing is solved.
