Method and device for adjusting face region automatic exposure control

The invention includes a method and a device for adjusting face region automatic exposure control. The method includes the following steps: dividing a face region into a plurality of sub-region blocks, doing statistics of the brightness of all the sub-region blocks, and constructing a brightness histogram of the color channels in the face region; analyzing the brightness histogram of the color channels according to the order of brightness from high to low, determining the lowest brightness for each color channel to meet the current automatic exposure control brightness according to the correspondence between brightness and the number of sub-region blocks, and determining the maximum brightness as a reference brightness from all the lowest brightness and a reference color channel corresponding to the reference brightness; and acquiring a target brightness corresponding to the current automatic exposure control brightness, and adjusting the brightness of the reference color channel according to the target brightness to enable the reference color channel to meet the condition that the lowest brightness thereof under the target brightness is the reference brightness. Thus, overexposure of the face region and color spots caused thereby are avoided, and the image quality is improved.

Nature antibacterial health-care ultraviolet-proofing polypropylene fiber

The invention provides an antibacterial health-care ultraviolet-proofing polypropylene fiber. The fiber is prepared by mixing the following components in percentage by weight: 1.5-10 percent of a green plum branch and leaf extract, 1-8 percent of a pomegranate bark extract, 60-85 percent of polypropylene slices and the balance of auxiliaries through fusing, granulating, re-fusing and spinning. Therefore, the bioactivators and nutrients existing in a compound mode of the green plum branch and leaf and pomegranate bark extract components are uniformly contained in the surface layer of and inside of the fiber, various textiles which are produced by the fiber and in contact with human skins are good in skin compatibility and strong in transdermal absorption capability, can be directly in contact with human skins, can play antibacterial and ultraviolet-proofing effects on a human body, can sustainably release the nutrients which can be absorbed by skin, realizes perfect combination of fiber and skin-caring and body-building, life cultivation and health care, and is advantageous to a human body to obtain more health benefits. Furthermore, waste resources can be recycled, so that huge social, ecological, environmental and economical benefits are implied in the fiber.
