1. A display apparatus, comprising:
an image detection unit configured to detect presence of an empty second subframe in input image data, in addition to a first subframe that displays an image;
a correction image generation unit configured to generate correction image data to correct the input image data;
a control unit configured to control display of the generated correction image data during a period of the empty second subframe, based on the detection of the presence of the empty second subframe, wherein the generated correction image data is displayed during the period of the empty second subframe; and
a display panel that includes a light modulation device provided for a pixel, and modulates irradiation light from a first light source, based on the input image data including the correction image data, wherein
the first light source illuminates the display panel during the period of the empty second subframe, and
the first light source has a first wavelength during the period of the empty second subframe which is different from a second wavelength of a second light source during a period of the first subframe.
