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 equipment
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

[0088] 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:

[0089] Step 110, judging whether the defogging mode is activated, and if the defogging mode is activated, proceed to step 120.

[0090] 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.

[0091] If the defogging mode is enabled, the shooting device will perform defogging p...

Embodiment 2

[0105] 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:

[0106] Step 210, judging whether the defogging mode is activated, and if the defogging mode is activated, proceed to step 220.

[0107] Step 220, 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.

[0108] 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 red (Red, R), green (Green, G), and blue (Blue, B). If the color of a pixel in the original preview image is RGB (R, G, B), then we It can be converted to grayscale by the following methods:

Embodiment 3

[0199] refer to image 3 , which shows a structural block diagram of an embodiment of an automatic defogging and photographing device according to an embodiment of the present invention, which may specifically include the following modules:

[0200] The judging module 310 is used to judge whether the defogging mode is activated; if the defogging mode is activated, enter the defogging processing module.

[0201] The defogging processing module 320 is configured to perform defogging processing on the original preview image of the shooting device to obtain a first preview image.

[0202] A preview module 330, configured to preview the first preview image after defogging processing in the shooting device.

[0203] The save confirmation module 340 is configured to determine whether to save the currently previewed first preview image according to the user's operation.

[0204] In the embodiment of the present invention, it can be judged whether the defogging mode is activated. If ...

Abstract

The embodiment of the invention provides an automatic defogging photographing method, device and equipment, and relates to the technical field of image processing. The method comprises following steps of judging whether a defogging mode is started or not; defogging an original preview image of a photographing device if the defogging mode is started, thus obtaining a first preview image; previewing the defogged first preview image in the photographing device; and determining whether to store the currently previewed first preview image or not according to operation of a user. The problems that a defogging technique based on hardware is large in hardware device size, inconvenient in carrying, relatively low in precision and relatively poor in image defogging effect, and the defogging technique based on software is complex in processing process and cannot satisfy the demand of the user for previewing the defogged image in real time, are solved. The method, the device and the equipment have the advantages that the carrying is convenient, the operation is simple; the image defogging effect is improved; and the demand of the user for previewing the defogged image in real time is satisfied.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an automatic defogging and photographing method, 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 equipment can reduce the impact of smog to a c...
