5.9 μm
PIXEL PITCHThe center-to-center distance between two pixels (photosites) on a sensor. The larger the photosites, the more light they can capture and the lower is the level of visible "noise" in captured images.
5.9 μm
Fixed
LOW-PASS FILTERA low-pass filter blurs fine details of an image to eliminate the moiré and the color artifacts of finely patterned structures. Without a low-pass filter images will appear sharper, but there is also a risk of moiré occurring in certain scenes.
