Patent ID: 8174542

Claim:
A video display apparatus comprising: a display panel; a converting circuit for executing nonlinear conversion for an input video signal to output a converted video signal; a display brightness featured value detecting circuit for detecting a display brightness featured value indicating a brightness of a display screen; an adjustment circuit for adjusting the converted video signal on the basis of said display brightness featured value to output an adjusted video signal; and a superimposing circuit for superimposing a signal for displaying textual information or an icon on the adjusted video signal to output a superimposed video signal to the display panel, wherein said display brightness featured value detecting circuit receives the superimposed video signal output from said superimposing circuit and calculates the display brightness featured value from the superimposed video signal in which textual information or an icon is superimposed thereon, and the adjustment circuit adjusts the converted video signal based on the calculated display brightness featured value such that the textual information or the icon is not adjusted based on the calculated display brightness featured value, and wherein an image is displayed on the basis of the superimposed video signal output from said superimposing circuit.
