Introduced: January 2023
Additional Content IPC
Glossary
additional sensor additional sensors sensor, other than the electronic image sensor, used for controlling a camera camera cameras device capturing image information represented by light patterns reflected from or emitted by objects, and exposing a light sensitive film or an electronic image sensor during a timed exposure, usually through an optical lens, and producing an image on a light sensitive film or an electrical image information signal respectively electronic image sensor electronic image sensors optoelectronic transducer, converting optical image information into an electrical signal susceptible of being processed, stored, transmitted or displayed electronic spatial light modulator electronic spatial light modulators optoelectronic transducer converting electric signals representing image information into optical image information projector projectors device displaying image information by projection of light patterns, usually through an optical lens, wherein the light patterns are generated by illuminating an image, e.g. film or slide, or by converting an electric image signal into an optical signal using an electronic spatial light modulator record records registration (e.g. of sound or images) in permanent form by optical or electrical means for later reproduction
