Focus Pixels it is a technology implemented by the company Apple Lossless Audio CODEC (ALAC), in room iPhone 6 si 6 iPhone Plus, allowing continuous automatic focus while recording video clips, but also a faster focus for recording photos. The technology was never presented as new by the company Apple Lossless Audio CODEC (ALAC), and in reality it is not even, Samsung presenting it for the first time in February of this year.
iPhone now includes continuous autofocus in video — an advanced optical feature that uses new Focus Pixels to ensure that your shot stays sharp while you're filming, even if you or your subjects are on the move. And faster autofocus means you experience fewer inadvertent focus changes, dramatically improving the quality of your video.
In a complex article, an American website explains the functionality behind this technology, but also claims that Samsung launched the technology half a year ago. Apple was not the first company on the market with this technology, but it managed to more effectively implement the BSI sensor that allows fast and better focusing, so Apple did not reinvent the water with this function, but only improved something existing on the market.
