The invention provides an exposure ratio automatic adjustment method and device. The method includes: acquiring multiple frames of images, and selecting a first image and a second image from the multiple frames of images, wherein the exposure time length of the first image is longer than the exposure time length of the second image; obtaining the second image of the first image a brightness and a third brightness of the second image; judging whether to adjust the actual exposure ratio according to the first brightness and the third brightness, and if so, adjusting the actual exposure ratio according to a preset adjustment value. In this way, the actual exposure ratio can be automatically adjusted according to the dynamic range and lighting conditions of the actual scene, and the adjustment can be made according to the preset adjustment value to ensure that the picture will not change abruptly.

The invention discloses a high-naturalness real-time beautifying method and device, and the method comprises the steps: employing a single-channel high-contrast image buffing method which employs the channel with the smallest number of interference noise points in three channels r, g and b, and effectively reduces the noise interference from other channels while reducing the calculation amount; obtaining the roughness information of skin through calculating a single-channel high-contrast image buffing image, thereby avoiding the skin distortion caused by the direct filtering of the image, and improving the naturalness of skin; and employing a layer mixing and overlapping method: employing a method of filtering, light softening and brightening mixing and overlapping to achieve an effect of skin buffing and whitening and to maintain the naturalness of the image after a buffing layer is calculated and obtained. The device is used at a mobile intelligent terminal, enables human face to remain natural while beautifying, whitening and buffing the face skin, greatly reduces the buffing track, and enables the reduction degree of edges and shadows of a human face to be high.

The invention provides an intelligent plate bending and edge buckling machine. The intelligent plate bending and edge buckling machine comprises a working table, a bending die, a working frame, a corrugated bending device and an edge buckling device. According to the intelligent plate bending and edge buckling machine, the problems that when an existing bending machine is used for producing roundsteel sheets with different diameters in a bending manner in the process of bending semicircular steel sheets, the bending heads and the bending lower dies need to be frequently replaced, and the production efficiency is influenced are solved; the problems that in the process of stamping the corrugated convex body structure, raised corrugations is caused to generate springback, springback occurs due to the action of stress in once stamping, and the product quality is influenced are solved; and the problems that when the existing bending machine bends the corners of the plates, prismatic creases at the corners are caused, and the later stitching is affected, so that the splicing of two semi-circular corrugated pipes cannot be attached, the curved surface after the later joint is not smooth,the corrugated creases are prone to cause the corrugated pipe to be buried in soil for a long time to be extruded and broken along the crease direction of the corrugated pipe due to the pressure of the soil, and use is affected are solved.

The invention relates to a histogram debugging method of a colored image and a debugging system thereof. According to the method, subarea nodes and subarea thresholds of a histogram of a colored image are arranged; according to an obtained node group with the thresholds, weighted translation calculation is carried out on each gray scale to obtain offset gray scales; and then each the gray scale of the colored image is replaced into each the offset gray scale. In addition, the system comprises a subarea node module, a subarea threshold module, a histogram subarea module, a threshold setting module, a gray scale transformation module and an image correction module. According to the invention, the following advantages are provided: novel functions, simple realization, low cost, and obvious debugging effect and the like. Moreover, according to the invention, a histogram is utilized to realize debugging on RGB image gray scale by a user. Therefore, a limitation on a gray scale debugging function of preset software can be broken through and furthermore, the user can set a random interval of a histogram of an image and a random threshold in the interval according to own needs of the user, thereby embodying strong interactivity, flexibility and generality. Therefore, the invention has a wide application prospect.
