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) Synthesis rate of 30 FPS, 540p on iPhone 7 30FPS, 720p on iPhone XS 60FPS, 1080p on iPhone 11 or greater It is controlled by the GPU family. Record FHD 1080p, 60FPS with A13 or greater HD, 30FPS recording with A11, A12 540p, 30FPS recording with A10
