How to open the beauty of Apple's mobile phone camera

The way to open the beauty of Apple's mobile phone camera is to slide up and down in the lower functional area of the camera, select the filter icon above, and select the band family above with the bright filter.

Mobile phone: iPhone 1 1

System: IOS 13.6

A camera is a kind of equipment that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment and astronomical observation equipment.

After the light reflected by the photographed scene is exposed by the lens, camera lens and shutter, the photographed scene forms a latent image on the photosensitive material in the camera box, which is developed and fixed to form a permanent image. This technology is called photography, which is divided into general photography and professional photography. 2065438+In September 2008, the Harmonized System Committee of the World Customs Organization classified UAVs as flying cameras.

The principle of beauty filter

There is also a professional name called color filter, which is one of the most popular filter solutions at present. By adjusting the parameters such as brightness, contrast, hue and dark angle of different pixel values, we can get the effect of different tones from the original image, which can be called color and color filter.

At present, the principle of color filters used in beauty SDK is to identify, map and color through color search algorithm, which is collectively called LUT color filters, which can be understood as an optimized and upgraded version of ordinary color filters. And the power consumption when using the filter is effectively reduced. Changing the pixels of an image is an important step to realize geometric filtering. You can think of the special effects of the mirror. This kind of filter has nothing to do with the color of stripe pattern, and it mainly realizes special effects by changing the geometric information of pixels.
