Equally 8 MP Camera iPhone 5S More Strikes
In the middle of the " megapixel wars " antarprodusen smartphones , Apple took a bit of a surprise move with fixed pairing 8 -megapixel iSight camera for its new flagship phone , the iPhone 5S .
The number is the same as the camera that had been used the previous two generations of the iPhone , the iPhone 4S and iPhone 5 , so that eliminates a little attraction iPhone 5S in the eyes of a novice user .
However , if the iPhone 5S camera actually the same as their predecessors ? It was not well . According to Apple , is actually a series of improvements have been implemented under the number " 8 megapixel " that seem conservative . What is it ? Here's the translation of KompasTekno , as excerpted from TechCrunch .
Larger sensor
High resolution does have its own advantages . Take the example of the Nokia Lumia 1020 with its 41 megapixel camera which is claimed to capture photos so detailed that can perform digital zoom without degrading the quality .
Rather than increase the megapixels , Apple decided to take the opposite , namely to maintain a resolution of 8 megapixels , but by increasing the size of the sensor to be 15 percent larger than on previous iPhone cameras .
Photodiode size ( pixels ) on the sensor which captures light duty was increased from 1.4 microns to 1.5 microns .
This step is similar to that made by HTC through Ultrapixel cameras , where each pixel size was increased to 2 microns . However , the camera on the HTC One cut to just 4 -megapixel resolution , while Apple still maintains an 8 megapixel camera .
So , what is the importance of the larger pixel size ? Imagine pixels is a bucket and a light rain was coming down from the sky . The wider the bucket , the more water that can be accommodated within the same time period . That is, the light information that can be captured much more .
HTC
Pixel size on the HTC camera is able to capture more light than other smartphone sensors in general kamer
This leads to image quality - at least theoretically - better . Tone colors captured more diverse with a smoother transition , the level of noise (grain ) that appears in the photograph can be reduced .
To increase the light sensitivity further , Apple also expanded the size of the aperture on the camera to f2.2 iPhone 5S or fourth stop wider than F2.4 aperture on the iPhone 5 .

Apple claims increase by 15 percent the size of the sensor also increases light sensitivity as much as 33 percent . However , even with magnification , the iPhone 5S camera sensor is much smaller than a pocket camera owned ( Canon PowerShot G15 ) though , as can be seen in the above comparison , especially when compared to a DSLR camera ( Nikon D7000 ) that times - fold more large .
Quality iPhone 5S catches image can not be assessed while the device was still absent in the market . However, the sample photo below seems quite promising for the size of a smartphone camera .
Examples of the images Cnet iPhone 5S
Apple A7 processor
Not only sensor on the camera are changed by Apple . Apple 's new A7 processor also contribute to improving the quality of the images .
This processor has the Image Signal Processor ( ISP ) integrated , or commonly known as Digital Signal Processor in digital cameras . ISPs typically process all tasks related to image processing on iPhone 5S , including color correction , white balance settings , format conversion , and much more .
Well , the iPhone 5S ISP has a number of new capabilities , such as the so-called tone mapping to improve coverage in photos and tonal matrix Autofocus metering with 15 zone focus .
This latter feature commonly found in digital SLR cameras and is useful for generating accurate exposure even in difficult lighting conditions , for example when the user take a picture in front of the sunset .
A7 processor speed higher also allows iPhone 5S take multiple images at once in a single snapshot and choose the most good or sharp . This can be done either in single shot mode and the " burst mode " with a speed of 10 FPS .

For the burst mode , the iPhone 5S will automatically select the images based on a number of criteria , the accuracy of exposure , sharpness , face detection , as well as the people in the photo when the subject is smiling or closing his eyes . Analysis is performed in real-time without user intervention .
The best selection results were presented to the user to choose from . The purpose is to facilitate the automatic selection of the photo selection process burst which can amount to hundreds .
" Flash " two colors
The most striking difference from the iPhone 5S with its predecessor is the flash unit " True Tone " which has two LEDs with different colors , namely white and yellow .
What's the point ? Flash on a smartphone or digital camera has a color temperature set to the same as sunlight . When used in the same light conditions with flash color temperature (such as fill - light in the daytime ) , the picture seemed to have a uniform color .

However , when users take photos with flash in different lighting conditions with the flash , such as in a room with a light yellowish color , the flash illuminated the subject will look different from the surrounding environment . A common color is the subject of " neutral " , while the background color is too yellow .
Problem is to be addressed by the iPhone's flash 5S True Tone . With the two different LED colors , the flash is able to produce different color temperatures also vary to suit the environmental conditions .
On DSLR cameras , color temperature difference is usually overcome by making a colored flash light output equal to the perimeter. The trick is to put a colored filter ( gel ) in front of the flash.

Apple claims that the True Tone can produce 1,000 color variations to match the flash of light sources , from the candle flame until the sun in broad daylight . In addition to balancing the flash with color output environments , True Tone also known to produce skin tones are more natural subjects .
Two LEDs flash at True Tone will likely not " shoot " in full force on every snap because the iPhone 5 should balance the output ratio of the two to produce the required color combination .

For light conditions that are not too " yellow " , for example , may be just the yellow LED will be lit with low intensity . So , should the output power of the flash True Tone would not be much different from previous generations .
In addition , True Tone can not seem to do much in the condition under fluorescent lights whose color is more likely to lead to the green spectrum , while it only has an LED flash additional yellow .
Penstablil image
Anti - shock mechanism or feature image stabilization on the iPhone 5S is quite interesting . According to Apple's description , to reduce the effect of blurring due to movement of the user when low-light conditions , the camera iPhone 5S take a lot of photos and take the parts most sharply in each of the image to produce the final image at an optimum sharpness .

Image Stabilization is actually tackle the problem only blurry because of camera movement , not subject movement , such as wind-blown leaves .
However , through a combination of anti - shock features and taking a lot of pictures at once ( multi -shot ) , iPhone 5S should be able to deal with blurry because of camera movement and subject simultaneously .
Video " slow motion "
called the iPhone 5S can record 720p HD video in 120 fps frame rate that can be played back at 30 fps in slow motion so that it displays ( 25 percent ) .
Interestingly , users can choose to display the slow motion on certain segments in the video , while the rest are running at normal speed .
Panorama
The ability to record panoramic images with resolutions up to 28 megapixels actually been around on the iPhone 5 . On iPhone 5s , image capture mode is enhanced even further through the automatic exposure correction features for each frame were combined into a panorama.
As a result , called the iPhone 5S is able to capture landscape photos with consistent exposure over different inter - area in the image , as in the example below .

There are also features shooting in a square aspect ratio ( 1:1 ) , like in Instagram . This one is the default operating system iOS 7 . Both slow motion mode , panorama , or square aspect ratio accessed through the main display and the camera application can be selected simply by swiping the finger .
