New Canon Patent Indicates Touchscreens On DSLRs

The most I have seen of a touchscreen on a digital camera is that Ashton Kutcher Nikon Coolpix commercial.  Canon is ready to bring this novelty to DSLRs apparently, or at least they published a patent for the technology.

The patent is a little more specific than just a DSLR touchscreen, which would be difficult to patent. The 13 page patent mostly focuses on a touch screen that can prevent parts of your face from accidently changing settings when brought to your eye to take photos.

In the patent, there is the possibility of allowing users to register what their dominant eye is, either right or left, so that the camera can detect the registered eye when brought to the viewfinder, disabling the portion of the touchscreen the would be most likely to accidently be touched by your face.

The patent mentions some of the features of the touchscreen. It seems the main use will be to adjust your settings- sliding your finger across the screen vertically will change the aperture, while sliding it horizontally with change the shutter speed.

Other features mentioned in the patent include focus detection area, exposure correction value, flash adjustment correction value, metering mode, drive mode, ISO, auto-focus mode, and white balance mode. In other words, your basic menu options.

What do you think of touch screens? Could it be more of a hassle than helpful. Either way, do you think it will be of any importance underwater? Let us know in the comments below.
