Patent ID: 6972804

Claim:
An image processing apparatus comprising: separating means for separating data in a plurality of formats from a broadcast video signal; layer image signal generating means for generating a plurality of layer image signals for data in said plurality of formats such that each of the plurality of image signals of data in each of the formats is superimposable on said data in the plurality of formats, wherein each said layer image signal being generated on the basis of an arbitrarily changeable form; means for generating a display section signal for said each layer image signal, said display section signal being generated on the basis of an arbitrarily changeable form, and adaptive image processing means for adaptively image processing said each layer image signal according to preset parameters to enable parameters of said each layer image signal to be individually optimally adjusted for viewing, said preset parameters including a sweep rate of said each layer image signal, wherein the sweep rate is adjusted in accordance with a luminance difference.
