Abstract
A video analysis unit calculates an intensity of re-entering illumination light that is first polarized light, among first polarized light entering a reflective liquid crystal display element which is included in illumination light having the first polarized light and second polarized light, for each pixel constituting a target frame, the first polarized light being reflected by the reflective liquid crystal display element without being modulated by the reflective liquid crystal display element, returning to a position closer to a light source unit, and re-entering the reflective liquid crystal display element. The video analysis unit calculates a sum obtained by summing the intensity of the re-entering illumination light calculated for all pixels. A video correction amount determining unit determines a correction amount to be added to or subtracted from a pixel value of each pixel according to a difference between the sum and a reference sum of a reference frame image.
