ABSTRACT:
An X-ray image displaying apparatus including a CPU, a video memory for storing image data, palette registers to which conducts the gradient conversion on image data stored in the video memory, DA converters for converting image data output from the palette registers into a color video signal, a monitoring device for receiving the color video signal and color-displaying an X-ray image, and a video printer for displaying the image on a recording medium. An interested region width setting switch and an interested region position setting switch are connected to a keyboard. The gradient characteristics of the palette registers are set to be .gamma.>1 in an interested region, and to be y=1 in an uninterested region.
