The French site of "LCE" has questioned the importance of multiple sensors, which have become a playground between smart phone manufacturers, who switched to two-way mode then triple.
In 2013, Huawei installed three cameras on some smartphones, Samsung also integrated three back-to-back cameras on the Galaxy A7 and four on the Galaxy A9, Nokia also installed five cameras on the iPhone, Nokia 9, while LG sets up a camera with 16 cameras at a time.
According to Nikola Tawash of DX Omark, expert in the quality assessment of smart phone cameras, smart phone camera makers are operating in harsher conditions than their counterparts in phone manufacturers traditional. They must multiply the sensors (cameras) and reduce Resize and reduce the image processing programs.
According to Camille Castellnell, product manager at Samsung, image quality is now a key factor in the selection and purchase of smartphones, so that more sensors are implanted in these phones. It is not a coincidence that the first qualitative development of the image was achieved by middle-class phones such as Galaxy C, ie 7 or 9, in order to promote it to from an older audience and is generally excited about this type of innovation.

"The multiplicity of sensors guarantees very clean and easily controllable images," explains François Hengant, Marketing Director at Huawei, France.
Sensors are used in other cameras to widen viewing angles, enlarge or reduce the image, and improve image quality, especially if the brightness is poor.
The necessary processing programs can be multi-sensor, because they improve the image quality, especially thanks to the image signal processor (ISP), and offer a more perfect and more detailed image with superior dynamic range. (HDR), explained the site.
megapixels
Camel Castellin explains that the option here is due to the needs of the image. If changes are needed or printed, the most important thing is to increase the number of megapixels.
The most important thing in all cases is that the camera takes more light when opened to ensure the realization of beautiful images. The next competition will be the opportunity to take a good image in the center of insufficient lighting or a dark night, as expected by the site of the article.
