1. A display apparatus comprising:
a display unit having pixels each of which is formed of a self-luminous element; and a controller configured to divide the display unit into function dependent luminous regions, and to reduce luminance of the pixels in the function dependent luminous regions when the pixels in the function dependent luminous regions have not changed for a predetermined period of time or longer, wherein a main-and-sub relationship between different function dependent luminous regions having non-contiguous boundaries with regard to luminous control is preset such that luminous changes in one function dependent luminous region will affect luminosity in another function dependent luminous region, the controller is configured to simultaneously reduce, based on the main-and-sub relationship, luminance of the function dependent luminous regions to which a sub-part of the main-and-sub relationship is assigned when luminance of the function dependent luminous regions to which a main-part of the main-and-sub relationship is assigned is to be reduced, the function dependent luminous regions are defined by the pixels whose luminance has not changed for the predetermined period of time or longer, and the function dependent luminous regions are determined depending on luminance change of the pixels included therein. |
