New Panasonic Sensor Tech Significantly Improves Low Light Performance


This is a brief excerpt from PetaPixel




The folks at Panasonic just developed an exciting new sensor technology that could significantly improve low light performance in all types of cameras very soon. Calling it a sensor technology is a bit misleading, however, because no improvements have been made to the actual sensor at all; instead, Panasonic has decided to change what sits in front of the sensor: the traditional color filter.

In order to generate a color image, most cameras use the same type of color filter in front of their image sensors. That traditional filter works by placing red, green, and blue filters in front of each individual pixel. While this works just fine, it also decreases the amount of light that hits the sensor by 50 to 70 percent.

By doing away with the filter and installing a film of “micro color splitters” instead, Panasonic is able to allow all of the light to pass through, essentially doubling the amount of light that arrives on target.

Here’s an example of two photos taken using the same type of sensor with the same settings at f/4.0. One was taken using a traditional color filter, the other using Panasonic’s new splitters:


We won’t go into the …
