Abstract: In an apparatus for modulating light, a spatial light modulator includes a plurality of pixels and configured to modulate input light in response to a drive voltage for each of the pixels. An input value setting unit is configured to set an input value for the each of pixels. The input value is a digital value, an entire gray level of the digital value is “N”, and “N” is a natural number. A converting unit is configured to convert the input value to a control value. A control value is a digital value, an entire gray level of the control value is “M”, and “M” is a natural number greater than “N”. A driving unit is configured to convert the control value to a voltage value and drive the each of the pixels in response to the drive voltage corresponding to the voltage value.
