Abstract
In a television image display apparatus, one field of an input video signal is divided into a plurality of areas in each of which image information is sampled, and an arithmetic processor provides a video control signal on the basis of preset adjusting data received from a memory and the sampled image information. Luminance, chrominance or sharpness levels can be automatically controlled for each field by such video control signal to maintain the video display in an optimum state. Noise problems typically associated with dark images or weak electric fields are eliminated, while improving the image quality by adjusting the video output for each field.
