ABSTRACT:
A presentation display apparatus including a data storage section for storing a plurality of explanative image data each having (R), (G) and (B) color image components, a data processing section for adding, to the explanative image data from the data storage section, function select image data different in color component from the explanative image data, an image memory for storing the image data of one screen image output from the data processing section, a listener's first display device for displaying the image data which is delivered from image memory and a speaker's second display device. The image data output from the image memory is supplied through a first color converter to the listener's display device and through a second color converter to the speaker's display device. In the first color converter, the explanative image data is alone directly delivered as conversion image data in spite of function select menu image data, so that only the explanative (R)/(G)/(B) image is displayed on the listener's display device. In the second converter, the (R)/(G)/(B) input data are directly output as conversion image data when the function select image data is "0" and otherwise converted to all "1" when the function select menu image is "1" so that the function select menu and (R)/(G)/(B) explanative image are overlappingly displayed on the second display device.
