-Overview-
Slit scan is different from the actual time when shooting with an analog camera by attaching a paper with a slit in front of the camera lens, lengthening the exposure time and moving it in the vertical direction with the slit. It is a technique to take the exposure of a single photo.

Strictly speaking, STRATUM does not install a slit in front of the camera like slit scan, but it stores digitally captured data in memory, slices it in any direction, combines it for each frame and shoots in real time. 
Due to the remarkable development of mobile devices in recent years, STRATUM has accumulated about 500 FHD images of 240FPS (*1) high-speed camera equipped with iOS, and composites and takes 500 photos at a time at a high frame rate of 60FPS.


-Spec-
In Stratum, each device limits the composition rate and the size of the composite image in order to perform the most reasonable processing possible for each device. The composite rate is different from the shooting rate. Any model capable of high-speed shooting can shoot at 240 FPS. (*2)
