1. A signal processing apparatus comprising:
a signal processing unit configured to
acquire, in changing a video signal from a low luminance display signal to a high luminance display signal by luminance enhancement, an accumulated load increase amount obtained by measuring and accumulating amounts of increase in load on a display panel caused by luminance enhancement, and
adaptively control, in reference to the accumulated load increase amount acquired, a first gain for improving luminance of the video signal, according to a degree of effect of deterioration in element of the display panel, wherein
the signal processing unit additionally adds the first gain to a second gain that is used for luminance enhancement, to thereby enhance the luminance of the video signal.
