Xiaomi Reveal Under Display Camera Technology

The fight over notches is quickly becoming a thing of the past, with companies like Oppo and Xiaomi already working on transparent display cameras that hide the sensor beneath the screen — no notch required. Today, Xiaomi senior vice president Wang Xiang tweeted a series of slides that explained more about how the feature actually works, via DPReview.For Xiaomi’s implementation of the feature, the camera is embedded in the top of the device, as usual. But instead of putting a border around it (a notch) or cutting a hole in the screen (a hole-punch display), the camera is covered with a “special-low-reflective glass with high transmittance.”Xiaomi says the setup allows the area of the display to become transparent to take pictures, and the transparent display then cleverly doubles as the camera lens on top.Xiaomi also notes that by not trying to make the camera (and, therefore, the inevitable notch) as small as possible, the transparent display system allows for a larger sensor and better image quality than its existing teardrop notches.It doesn’t appear to be a perfect system yet: in Xiaomi’s slides, you can still see a faint outline of the camera lens underneath the active display, but it’s at least a useable area of the screen instead of one that’s obscured entirely by a monolithic notch on top. Compared to other notch-less solutions, like pop-up lenses or flipping cameras, there are no mechanically moving parts to worry about here.All we need now is a phone that actually uses the new camera. All Xiaomi is saying for now is that it’s “currently exploring the possibility.” Although knowing the company’s love for experimental smartphones that push new form factors and technology, hopefully we won’t have to wait too long.

Batteries in Camera

Extract camera information from any Jpeg ( Jpg) image... In which batteries produce energy from a chemical reaction, when two unlike materials (positive and negative plates) are immersed in the electrolyte. ... The battery can no longer deliver electricity at a useful voltage. Feeding electrical current back into it can recharge a discharged battery..

Tripods

In photography, a tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment. All photographic tripods have three legs and a mounting head to couple with a camera. The mounting head usually includes a thumbscrew that mates to a female threaded receptacle on the camera, as well as a mechanism to be able to rotate and tilt the camera when it is mounted on the tripod.

LCD Hoods in camera

Glare and the bright sunlight can really affect the way your photos display on the LCD display on your camera, which means what you see may not really be what you get once you download your photos off the camera. To get a better picture (ha!) of your photos, use an LCD hood.
