Abstract: In a circuit provided with a phase comparator, a lock time is shortened. The phase comparator compares between a phase of a reference clock signal that has been input and a phase of a feedback clock signal, and outputs a comparison result. A charge pump generates a control voltage for control of a frequency of the feedback clock signal on the basis of the comparison result. A feedback unit generates the feedback clock signal in response to the control voltage. A stop detection unit detects whether or not the reference clock signal is stopped, and initializes the comparison result in a case where the reference clock signal is stopped.

A pixel value conversion section heightens colors of all pixels such that the background region uniformly takes on a background color having a predetermined luminance. A shadow/background processing section identifies the region of the shadow of the virtual object, sets the background region other than the shadow to the background color, and sets the shadow region to a color whose luminance is equal to or lower than that of the background color.
