1. A display apparatus comprising:
a signal processing circuitry configured to process a video signal; and
a display panel configured to display video based on the video signal, wherein
the signal processing circuitry is configured to:
acquire an accumulated load increase amount based on amounts of increase in load on the display panel caused by luminance enhancement,
control, in reference to the accumulated load increase amount acquired, a first gain for improving luminance of the video signal,
add the first gain to a second gain that is used for luminance enhancement to enhance the luminance of the video signal, and
limit a length of time of performing luminance enhancement on a same region of the display panel.
