A picture display device can indicate information of plural still pictures, and comprises an increased unit enclosing plural frame memory boards for inputting and storing the picture signals through a buffer circuit and indicating the pictures onto respective displays connected individually, an image file controller acting as a host controller, and a buffer board connected to the image controller and supplying the picture signals stored in the image file controller to a buffer circuit in the increased unit. Information of different pictures can be transmitted and stored respectively to plural sheets of the frame boards for indication only, thereby the information of respective pictures can be indicated on respective plural displays individually and simultaneously.

Picture display device

The invention provides a novel color image display apparatus having a constitution in which a frame memory is provided between a color palette and CRT display, and the frame memory stores color image data restored by the color palette before displaying color image data on the display screen. This constitution allows the apparatus to easily composite and display image information using a variety of palette data. The apparatus is also provided with a plurality of color palettes and image-composition means which composites color images restored by a plurality of color palettes, thus making it possible for the color image display apparatus to securely compose finer color images featuring improved flexibility.
