    Abstract: This disclosure makes it possible to provide a more favorable air floating video display apparatus. According to the present invention, it is possible to contribute to “Goal 3: Ensure healthy lives and promote well-being for all at all ages”, and “Goal 9: Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation” in the Sustainable Development Goals. An air floating video display apparatus includes a display apparatus configured to display a video, a retroreflection plate configured to reflect video light from the display apparatus and display an air floating video in air by the reflected light, and an image processor configured to perform image processing to the video displayed on the display apparatus. When an air floating video including a display of an object is displayed as the air floating video displayed by the air floating video display apparatus, the image processor performs an image processing to an image of the object displayed on the display apparatus, and the image processing has input/output characteristics that convert an input image having a pixel with low luminance into an output image having a pixel with increased luminance.
