Abstract: Digital methods so far have been used relatively little in picture origination equipment such as cameras and telecine, mainly because analog methods have been considered adequate and less expensive. There are signs, however, that the situation is slowly changing — as digital processing begins to be used for signals from image sensors. A complete all-digital channel has been in experimental use at the BBC for several years; stability and performance are good. Such all-digital channels may gain in popularity, owing to recent developments in flying-spot and solid-state telecines. Much depends on the availability of high-resolution (at least 11 bits) high-speed analog-to-digital converters. Use of line-array image sensors with digital storage can improve picture quality and simplify adjustment. Cameras with solid-state sensors are likely to need fairly complex correction systems. In principle the storage of element-to-element information is possible and will become more practicable as compact storage develops.
