What's new with a phone camera
Samsung's new Dual Pixel Pro phone camera promises better auto focus
Samsung just unveiled some exciting new smartphone camera technologies in a press release. The company unveiled a new camera called the 50MP ISOCELL GN2, which is expected to make its way onto the next generation of Samsung Galaxy devices.
With this new sensor, Samsung is promising faster and more accurate autofocus, which will make it much easier to capture a subject and get the picture you want before the opportunity goes by.
What's So Great About Samsung's Dual Pixel Pro Phone Tech?
If you are a Samsung fan who buys new Galaxy devices on launch, this new camera sensor is great news for you. Who doesn't want a camera that can automatically focus faster and more accurately?
Typically, Samsung (and Canon, which also use dual pixel technology) split each sensor pixel vertically for the technology to work. From there they receive light from slightly different angles. This allows the sensor to quickly and directly calculate the focus based on the difference between the two. In addition, all of the sensor's pixels are used for autofocus, which allows the lens to capture focus quickly without losing accuracy.

However, there are some small differences with this new Dual Pixel Pro technology announced by Samsung. Instead of dividing the pixels vertically, Samsung divides them diagonally. This allows each pixel to compare the light coming in from all directions, rather than narrowing it down to two as was the case with existing technology. In some situations, this can result in even faster autofocus without sacrificing accuracy.
Duckhyun Chang, Executive Vice President for Sensor Business at Samsung Electronics, spoke about the new technology:
"Our new ISOCELL GN2 features Dual Pixel Pro, an innovative all-direction autofocus solution that adds flexibility to capture moments as they unfold. With Smart ISO Pro and a host of advanced pixel technologies, images from GN2 are truer . to life than ever before. "
What else does the new Samsung camera do?
Faster and more accurate autofocus isn't the only thing this new 50MP ISOCELL GN2 camera brings to the table. It also has the ability to take photos in 100MP mode. In this mode, the GN2 rearranges the color pixels using an algorithm that creates three individual layers of 50 MP frames in green, red, and blue. These images are then upscaled to create a 100 MP resolution photo from the 50 MP sensor.
Samsung also announced staggered HDR, which uses roller shutters to take multiple pictures in short, medium, and long exposures. This is designed for bright scenes like sunsets or interiors with natural light through a window. It captures details and vivid colors in highlights and shadows and produces better images in such suboptimal situations.
When will we see this new camera?
According to Samsung, the new camera sensor is currently in mass production. We therefore expect that the next generation of Galaxy phones will be there. We'll have to wait for these to be closer to release to find out, however.
