Samsung has developed a new camera sensor technology
that offers the ability to simultaneously capture image and depth. The
breakthrough could potentially be applied to smartphones and other
devices as an alternative method of control where hand gestures could be
used to carry out functions without having to touch a screen or other
input. According to Tech-On, it uses a CMOS sensor with red, blue and green pixels, combined with an additional z-pixel for capturing depth.
The
new Samsung sensor can capture images at a resolution of 1,920x720
using its traditional RGB array, while it can also capture a depth image
at a resolution of 480x360 with the z-pixel. It is able to achieve its
depth capabilities by a special process whereby the z-pixel is located
beneath the RGB pixel array. Samsung’s boffins then placed a special
barrier between the RGB and z pixels allowing the light they capture to
give the effect that the z-pixel is three times its actual size.
In this early iteration of the new technology, Samsung used FSI
technology only. In future applications, BSI could be applied doubling
the quantum efficiency of the design further reducing cross-talk to the
RGB pixels.
