In February 2019, Prusa i3 MK3S was released, along with the Multi Material Upgrade 2S (MMU2S), which allows selecting any of 5 different materials for printing together automatically. [36] MK3S changes include a simplified opto-mechanical filament sensor, improved print cooling, and easier access to service the extruder.

The new video camera tube developed by Lubszynski, Rodda and McGee in 1934 was dubbed "the super-Emitron". This tube is a combination of the image dissector and the Emitron. It has an efficient photocathode that transforms the scene light into an electron image; the latter is then accelerated towards a target specially prepared for the emission ...
The camera projection matrix is derived from the intrinsic and extrinsic parameters of the camera, and is often represented by the series of transformations; e.g., a matrix of camera intrinsic parameters, a 3 × 3 rotation matrix, and a translation vector. The camera projection matrix can be used to associate points in a camera's image space ...
The first camera to be formatted for the new film was the Kodak M2. During the late 1960s, cameras were only formatted to film at 18 frames per second, but as technology improved, speeds such as 24 frame/s (the motion-picture standard) and faster speeds (for slow-motion filming) were incorporated into camera mechanics.
Canon began developing a still video system as early as 1977 following a secret presentation from Texas Instruments (TI). Processing the image data from a CCD sensor into a digital file would have required a supercomputer at the time, so a strategic decision was made to use analog recording methods, and Canon recruited Sony and other manufacturers to create a standard format, resulting in the ...
Flip cameras' video quality was unusually good for their prices and sizes. [8] They can record videos at different resolutions. FlipHD camcorders digitally record high-definition video at 1280 x 720 resolution using H.264 video compression, Advanced Audio Coding (AAC) audio compression and the MP4 file format, while the older models used a 640 x 480 resolution.
