TELEVISION RECEIVER INCLUDING SHADING CORRECTION WITHOUT DETERIORATING S/N RATIO

摘要

In a television receiver, shading correction is carried out without deteriorating the S/N ratio. In a television receiver comprising a CRT, shading correction means for supplying an image signal to a cathode of the CRT (cathode-ray tube) and for correcting brightness inequalities of an image formed on a fluorescent screen by way of electron beams which are increased/decreased in response to a change in potentials applied to a first grid of the CRT, the shading correction means supplies a shading correction signal to the first grid.
