Abstract
A image display unit is allowed to reproduce display characteristics substantially equivalent to that obtained with use of a cinema projector, when performing a image display based on a film image signal or an equivalent. The image display unit including: an image insertion section inserting an interpolation frame image into an input video signal as the film image signal or the equivalent; and a display section performing image display based on a video signal where the interpolation frame image is inserted. The image insertion section generates an optimized image as the interpolation frame image in which the insertion time period and the signal level are optimized based on display characteristics to be achieved in a projected image projected with the cinema film by a cinema projector, thereby to insert the optimized image into the input video signal at a position corresponding to a gap between frames of the cinema film.
