摘要:
In a television receiver, shading correction is carried out without deteriorating the S/N ratio. In a television receiver including a CRT, and a shading corrector 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 the potentials applied to a first grid of the CRT, the shading corrector supplies a shading correction signal to the first grid.
