Future iPhones may be able to take clearer pictures underwater, and apple is working on how to process and adjust images when it detects that the camera sensor is submerged. Although underwater photography is fun and imaginative shots can show things that you can’t see at ordinary times, it takes a lot of effort for a photographer to get a perfect picture. Simply placing the camera under water can work in places where the water is extremely clear, but not every water body can provide ideal conditions. < / P > < p > with the advent of waterproof hardware, the camera device can be more protected from underwater damage, but even amateur photographers can get good pictures with waterproof iPhones when they are close to the water surface. Even with perfect hardware, there are still obvious problems with such photography, such as the lack of available light due to turbid water surface and the reduction of long-distance visibility. There is even the problem of color difference. Compared with photography on the water surface, there may be a green color tone when shooting on water. < / P > < p > in a patent granted to Apple by the U.S. patent and Trademark Office on Tuesday, apple proposed a potential solution to this problem by analyzing several factors. After automatically detecting whether a photo is taken underwater, it is suggested that the device can make some changes to improve the probability of the image becoming a good photo. The detection may include collecting some data points that it can be used for processing, such as collecting the amount of ambient light through the color ambient light sensor, and measuring the ambient light spectrum above and below the water line to determine the amount of light absorbed by water. < / P > < p > from the water surface depth data, the distance from the object to be measured, the water pressure and orientation of the equipment can be combined with ambient light sensing and detection of backscattered light to characterize the theoretical water turbidity degree. Once identified, the device can adopt a variety of strategies to overcome the various challenges thrown out in that particular situation. For example, if the ambient light is not enough, the device may want to introduce more lighting on the body. Other post shot editing may include changing the hue of the image to reduce light absorbed or reflected by the water surface, and artificial water coloring to make it more ideal for blue rather than turbidity, and generally enhance contrast and other image attributes to make it easier for the assumed subject to see. < / P > < p > the patent also covers changes in the application process, such as removing & quot; are you sure? &To reduce the user’s cognitive burden and reduce processor requirements and battery life. It also includes that the device may take into account the reduced ability to input commands, such as when trying to use a touch screen underwater, the effect of the touch screen will be seriously reduced. Of course, apple is also working to improve the waterproof performance of the device, which has been explored in other patents, replacing the lightning port with contact and magnetically connected and aligned cables.
