Problems solved by technology

[0005] First of all, the hardware-based method is bulky and inconvenient to carry, and because different sensors only target a certain type of information, for example, infrared-based sensors are only sensitive to heat-generating targets, and cannot detect non-heat-dissipating signals in the scene. Effective detection, so the accuracy of the hardware method is low, and the defogging effect on the image is relatively poor
[0006] Secondly, most of the software-based defogging technologies use post-processing methods, and have not been effectively combined with smartphone shooting terminals.
When users want to defog the photos taken by smartphones, they can only copy them to the computer or use third-party software for processing, which makes the processing process more cumbersome and cannot satisfy the user's requirements for the defogged images. The need for real-time preview

Embodiment 1

[0122] refer to figure 1 , which shows a flow chart of the steps of an embodiment of an automatic defogging and photographing method according to an embodiment of the present invention, which may specifically include the following steps:

[0123] Step 110, judging whether the defogging mode is activated; if the defogging mode is activated, proceed to step 120.

[0124] Wherein, the defogging mode is a mode for performing a defogging operation on the preview image of the current shooting device. In the embodiment of the present invention, the user of the shooting device can choose whether to turn on the defogging mode according to the requirement. For example, the user of the shooting device can turn on or off the defogging mode by triggering the button of the shooting device or touching the display screen of the shooting device. This embodiment of the present invention is not limited.

[0125] If the defogging mode is enabled, the shooting device will perform defogging proce...

Embodiment 2

[0139] refer to figure 2 , which shows a flow chart of the steps of an embodiment of an automatic defogging and photographing method according to an embodiment of the present invention, which may specifically include the following steps:

[0140] Step 210, judging whether the defogging mode is activated; if the defogging mode is activated, proceed to step 220.

[0141] Step 220, displaying the haze removal level adjustment control on the preview interface, and receiving the haze removal level input by the user through the haze removal level adjustment control.

[0142] Step 230, for each pixel in the original preview image, extract the minimum value of the RGB components of each pixel to generate a grayscale image of the original preview image.

[0143] A grayscale image is an image represented by grayscale (Gray), in which the logarithmic relationship between white and black is divided into several levels, called grayscale. Any color is composed of three primary colors of ...

Embodiment 3

[0226] refer to image 3 , which shows a flow chart of the steps of an embodiment of an automatic defogging and photographing method according to an embodiment of the present invention, which may specifically include the following steps:

[0227] Step 310, judging whether the defogging mode is activated; if the defogging mode is activated, proceed to step 320.

[0228] Step 320, for each pixel in the original preview image displayed on the preview interface, extract the minimum value of the RGB components of each pixel, and generate a grayscale image of the original preview image.

[0229] Step 330, displaying the haze removal level adjustment control on the preview interface, and receiving the haze removal level input by the user through the haze removal level adjustment control.

[0230] Step 340, obtaining the atmospheric light intensity coefficient.

[0231] In this embodiment of the present invention, this step may also be performed before any step directly from step 32...

Abstract

Embodiments of the present invention provide an automatic defogging method, device and equipment for photographing, and relate to the technical field of image processing. The method includes: determining whether the dehazing mode is activated; if the dehazing mode is activated, displaying the dehazing level adjustment control on the preview interface, and receiving the dehazing level input by the user through the dehazing level adjustment control; when After receiving the dehaze level input by the user, the current original preview image of the shooting device is dehazed according to the dehaze level to obtain the first preview image; the dehazed first preview image is Preview is performed in the preview interface of the shooting device; when the user's operation to confirm shooting is received, the first preview image currently displayed on the preview interface is saved. While being portable and simple to operate, it improves the dehazing effect on images and satisfies the beneficial effects of users being able to adjust the degree of dehazing and previewing the dehazed image in real time.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic defogging and photographing method, an automatic defogging and photographing device and an automatic defogging and photographing device. Background technique [0002] With the rapid development of industrial technology, the air quality has been continuously reduced. Among them, the phenomenon of fog and haze is increasing day by day, which reduces the visibility of the outdoor environment, and the reduction of visibility has a great impact on the quality of video images. For example, the impact on photography and taking pictures. Generally, in foggy weather, the visibility of the image scene is low, which leads to serious degradation of the image captured by the optical sensor, and when the imaging details are serious, it will degrade to a state that is difficult to recognize. Usually, for professional photographers, the use of high-quality hardware equipm...
