![]() ![]() Earlier, cameras were very large devices, almost always in two sections. Improvements in video camera tubes in the 1930s ushered in the era of electronic television. The earliest video cameras were mechanical flying-spot scanners which were in use in the 1920s and 1930s during the period of mechanical television. The video signal from a professional video camera can be broadcast live, or is meant to be edited quickly with little or no color or exposure adjustments needed. A digital movie camera is designed for movies or scripted television to record files that are then color corrected during post-production. Nowadays, HDTV cameras designed for broadcast television, news, sports, events and other works such as reality TV are termed as professional video cameras. The distinction between professional video cameras and movie cameras became much smaller as HD digital video cameras with sensors the same size as 35mm movie cameras - plus dynamic range ( exposure latitude) and color rendition approaching film quality - were introduced in the late 2010s.
