2. Any of several electronic scanning and imaging devices; such as, a gamma camera, that enables radiation patterns to be visualized on a cathode-ray tube, computer printout, photographic film, etc.
3. The part of a television transmitting apparatus that receives the primary image on a light-sensitive cathode-ray tube and transforms it into electrical impulses.
4. Any enclosed space; cavity, or chamber.
5. A judge's private chamber.
6. Etymology: in Modern Latin camera obscura, "dark chamber" (a black box with a lens that could project images of external objects), from Latin camera, "vaulted room"; from Greek kamara, "vaulted chamber".

Contrasted with camera lucida, Latin, "light chamber"; which uses prisms to produce an image on paper beneath the instrument, which can be traced.

Shortened to "camera" when modern photography began, in about 1840; which was extended to television filming devices in about 1928.

Schmidt camera, Schmidt telescope
1. A telescope-camera able to take pictures covering a wide area of the sky without optical problems by virtue of having a specially shaped corrector plate near its upper-end.
2. A wide-angle photographic telescope used in astronomy which has a special internal mirror to correct optical aberrations.
3. A type of reflecting telescope; more accurately, a large camera, in which the coma produced by a spherical concave mirror is compensated for by a thin correcting lens placed at the opening of the telescope tube and has a usable field of 0°.6.

The Schmidt telescope has a corrector lens that prevents distortions of the image which is produced by its large spherical mirror.

Something called spherical aberration occurs when the uncorrected mirror does not focus all of the light rays at the same point.
