CAMERA SENSORS (EXPLAINED)!

Helen Keller once wrote:

“The best and most beautiful things in the world cannot be seen or even touched. They must be felt by heart.”

Surprising this quote would hold true during the times when the best and most beautiful things couldn’t be captured. But, today we live in a world of memories where the only thing we yearn is to recreate those beautiful and the best moments of the past. A simple photograph from the past would lead you back to those golden years of magnanimous differences. Though now the meaning of photo has changed since the past eras. Today with all the Pure HD (1080p) content then the famous 4k contents have changed the way we look at memories. It’s just a fact that we don’t want to miss a pixel of that beautiful moments.

A great Greek philosopher Plato once said:

“Necessity is the mother of invention.”

And through those necessities does these inventions spring in and out the world. The modern etymology of Camera obscura signifies a dark room (a black box with lens). While now there is no such definition anything and everything that fits your mobile phone or a SLR is a camera. We will today see through the different camera technologies present in market today. There are chiefly three prominent technologies today present in the market:

(1) Back Illumination sensor- Considered to the forte of Apple, it included this sensor in almost all the latest iteration of iDevices. This sensors are made up of a variety of light sensitive layers that help in maximum exposure of light to take more clear photographs on the low light condition, while on the other hand they restrict excessive light from entering the lens giving grains and noise in the images. Due to which photos from an 8MP iPhone 5s could beat the clarity of 13MP Samsung galaxy devices. Thus, this illumination sensor is so photosensitive to light that they give the best shots in the low light condition. Due to lack of stabilization in it the photos come up with a bit vibration but overall the give very good picture keeping in mind all the hues and colours of the surroundings.

(2) Optical Image stabilization-Almost all modern smartphones and DSLR’s have it. The come with different aperture speeds and focal length, but they help in stabilizing the image. It is also called as the vibration reduction sensor. People usually confuse it to take good picture of moving object though it is not. The moving objects will still be unclear, it will only help in stabilizing a stationary picture and giving a sharper image as a result. Many of the Canon devices use this method. The best example in the smartphone is the google NEXUS 5. The OIS also comes in two types like the IN LENS and IN CAMERA. Both have their own disadvantages and advantages but the IN CAMERA OIS giving very fast images while the earlier one comes with different lens and configurable.

(3) Laser Image stabilization-One of the latest iteration in the smartphone market but an old one for the DSLR’s. This fancy technique has a fancy little laser as in the case of LG G3 following the focus and it can focus on anything simultaneously and faster in less than 5 sec. This method works prominently with the nearing shots which help the laser to reflect properly and thereby focusing properly on the images. One of my Nikon camera has a green laser which falls on the object to be focused. The LG G3 has been making quite a lot of noise for this LIS sensor it does help in delivering picture perfect images in the good light condition but it gives a bit low resolution picture with little noise under the low light conditions.

Here, all the discussed sensors have its own pros and cons and be used according to the way they are utilized. Even if you have the best sensor but then if they are not utilized accordingly by the processor then it is of no use. The one last concept to be dealt with is the ultrapixel configuration in the HTC ONE series. The ultrapixel used here have an ability to record each pixel in denser manner giving very good picture resolution but the only problem with this is – it leads to overexposure of the images giving extremely colour saturation images. There are also complaints of images having a pink hue around the images but that is prominently due to the ultrapixel concept. Though it is currently not worth the money investing for keeping in mind the 40k to 50k selling brackets of such high end camera smartphones.

Here it is all about the best camera sensors. Keep visiting for more information on the smartphones updates.
