Abstract:
1. A waveform observing apparatus, comprising a touch panel in a display section and allowing a handwritten comment to be written in a desired place of a displayed waveform by use of the touch panel, the apparatus including: a first image information generating device for generating first handwritten comment image information which includes a compression ratio of a waveform display at the time of writing a first handwritten comment by use of the touch panel, along with first image information of the first handwritten comment; a simple indication registering device for registering a simple indication for displaying the simple indication corresponding to the first handwritten comment; a memory device for storing the first handwritten comment image information and the registered simple indication; a compression ratio setting device for setting a compression ratio of the waveform display of the waveform observing apparatus; and a control device, which calls up the first handwritten comment image information of the first handwritten comment from the memory device and displays as superimposing the first image information on the displayed waveform having a time-axial position where the first handwritten comment should be displayed in the display section of the waveform observing apparatus on the occasion when the waveform is displayed in determination of the compression ratio set by the compression ratio setting device to be the same as the compression ratio at the time of writing the handwritten comment from the waveform on display in the waveform observing apparatus at the time of displaying the image, and calls up the simple indication corresponding to the first handwritten comment from the memory device and displays as superimposing the first image information on the waveform having a time-axial position where the first handwritten comment should be displayed in the display section of the waveform observing apparatus on the occasion when the waveform is displayed in determination of the compression ratio set by the compression ratio setting device to be different from the compression ratio at the time of writing the first handwritten comment and not within the allowable range for displacement of the image of the first handwritten comment from the waveform on display in the waveform observing apparatus at the time of displaying the image, or calls up the first handwritten comment image information of the first handwritten comment from the memory device and displays as superimposing the first image information on the displayed waveform having a time-axial position where the first handwritten comment should be displayed in the display section of the waveform observing apparatus on the occasion when the waveform is displayed in determination of the compression ratio set by the compression ratio setting device to be different from the compression ratio at the time of writing the first handwritten comment but within the allowable range for displacement of the image of the first handwritten comment from the waveform on display in the waveform observing apparatus at the time of displaying the image.
