PROBLEM TO BE SOLVED: To provide a data presentation apparatus with simple constitution capable of recording an image for audience and an image for a presenter onto a recording data and displaying the images respectively for the audience and the presenter as the separate images. SOLUTION: An image S2 to be concealed which is desired to be concealed as required is recorded on a paper material S by an infrared ray absorbent paint and in addition, a main image S1 visually confirmed by a visible light is also recorded on the paper material S. The paper material S is irradiated with infrared rays by an infrared ray light 23 to photograph the paper material S and a photographed image (main image S1 + image S2 to be concealed) is displayed on a presenter monitor 30. The photographed image (only the main image S1) whose image S2 is concealed is projected on an audience screen without emitting the infrared ray. Switching the image changeover switch 44 can display the photographed image (main image S1 + image S2 to be concealed) displayed on the monitor 30 onto the screen as required.
