Claims (1)

[Scope of Claim for Utility Model Registration] Background image data creation means for creating background image data so that the baseline and scale of each channel are displayed in a predetermined color at a predetermined screen position in response to a setting operation on an external operation panel; It is equipped with a waveform image data creation means that creates waveform image data so that the biosignals of multiple input channels are displayed in different colors at predetermined screen positions according to setting operations, and the waveform image data is created from a memory that stores these image data. A biological signal color display device configured to display color image signals sequentially read out in synchronization with the sweep of a color cathode ray tube on its screen, and waveforms in different colors with the baseline and scale of the channel to which it belongs as a background screen, wherein the external The operation panel is provided with a color background range setting means for setting a scale range between the baseline and the maximum scale of the affiliated channel for one or more channels as a color background display, and the background image data creation means is set to display the scale range between the baseline and the maximum scale of the affiliated channel. A color display device characterized in that the color display device is configured to also create color background image data that fills the scale range in a band shape along the time axis with a waveform of 1 and a color different from the color background color of other channels.
