A display controller includes: an upper limit luminance value acquisition unit configured to acquire, for pixels of display devices, an upper limit luminance value of an absolute luminance value; a set luminance value setting unit configured to set a set luminance value so that the set luminance value is smaller than a maximum value among the upper limit luminance values; an input luminance value acquisition unit configured to acquire an input luminance value based on input data; an output gradation value generation unit configured to generate an output gradation value based on the input luminance value and the set luminance value; and an output controller configured to output the generated output gradation value, wherein the output gradation value generation unit is further configured to generate the output gradation value so that an output luminance value is equal to or smaller than the set luminance value.
