Image display device and image processing device

An image display device comprising:

• an image signal acquirer that acquires an image signal in which at least one frame image has been periodically thinned from among a plurality of temporally consecutive frame images;
• a motion vector detector that detects a motion vector of the present frame image by using at least two or more temporally adjacent frame images;
• an interpolation phase generator that generates an interpolation phase of an interpolation frame image on the basis of downsampling frame information representing a downsampling timing at which the at least one frame image of the image signal acquired by the image signal acquirer is thinned;
• an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase generated by the interpolation phase generator, on the basis of the image signal acquired by the image signal acquirer and the motion vector detected by the motion vector detector;
• and
• a display that displays an image signal including the interpolation frame image generated by the interpolation frame generator, wherein
• the interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods in which at least one frame image is thinned from among the plurality of frame images, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods.
