Apple looking for ways how to improve image processing so that pictures taken underwater using future iPhone models would look really good.

The possibility of using future iPhone models for taking clearer and more vivid photographs underwater is getting nearer. Apple revealed it is looking for better ways in terms of processing and adjusting images whenever it detects the camera sensor is submerged.

Underwater photography allows you to see the beauty that lies beneath the water. Imaginative shots taken by hobbyists underwater are very interesting to look at. However, it takes a huge effort for the photographer to capture the perfect image. This is where Apple comes in with its concept and idea of future iPhone models that hobbyists could use in capturing good images underwater.

Apple understands that underwater photography is not simply using a camera in subaquatic settings. While in some instances, submerging a camera in locations with extremely clear waters work, you must remember that not all body of water has the same condition. Apple believes that better image processing which the company plans to integrate into future iPhone models, taking that perfect underwater shot need not take a lot of effort or time.

In underwater photography, having water-resistant hardware is a must so photographers can submerge with it without damaging the equipment. Amateur photographers have captured decent images using water-resistant iPhones but only in situations where they are closer to the surface. Although using the same device several meters below the surface is not recommended as it might damage your iPhone. There is also the issue of reduced visibility due to murky water, as well as color differences. However, all of these might change with future iPhone models as envisioned by Apple.

On Tuesday, the US Patent and Trademark Office granted Apple's application for a new patent. The document submitted by the company had the title "Submersible electronic devices with imaging capabilities." In that same document, Apple proposes a possible solution to the problem, which it intends to integrate into future iPhone models.

In the document, Apple introduces several changes to its upcoming iOS devices, including future iPhone models, which the company says can improve the quality of images taken underwater. Image detection may include collecting several data points that the device can use in processing the shots. These include determining the amount of ambient light through a color ambient light sensor, which the iOS device can use to determine ambient light spectra in both above and below the waterline.

Apple is also looking to include in future iPhone models a depth data system which measures the distance of the device from the waterline, as well as distance from the subject, and other factors like water pressure and orientation. Combined with the ambient light sensing system, the company says the device can detect backscattered light and determine the murkiness of the water. Once it has all the data, the device will use multiple strategies to overcome the challenges present in a particular situation.
