Abstract
A video display apparatus includes a converting circuit for executing nonlinear conversion for an input signal, a display brightness featured value detecting circuit for detecting a display brightness featured value indicating a brightness of a display screen from the input signal, and an adjustment circuit receiving an output of the converting circuit for adjusting the received signal on the basis of the display brightness featured value. In addition, a superimposing circuit superimposes a signal for displaying textual information to be superimposed or a signal for displaying an icon to be superimposed on the input signal. The superimposing circuit is placed on a stage after the adjustment circuit, and the display brightness featured value detecting circuit is placed on a stage after the converting circuit and after the superimposing circuit. The display brightness featured value detecting circuit detects a display brightness featured value indicating brightness of the display screen in a state that the textual information or the icon is superimposed, and an image is displayed on the basis of an output of the superimposing circuit.
