Display system and display method

A display system, comprising

• a display, and
• a processor configured to:
• acquire first image data of a sample to be analyzed;
• perform first image processing on the first image data to generate second image data;
• perform second image processing on the second image data to generate third image data;
• perform third image processing on the third image data to generate fourth image data;
• and
• display, on the display, a first screen including a first identification image corresponding to the first image processing, a second identification image corresponding to the second image processing, and a third identification image corresponding to the third image processing
• in a case where the second identification image is selected, the processor is configured to display, on the display, a second screen including a first region, a second region, a boundary line dividing the first region and the second region, a first switching image, and a second switching image, and the processor is further configured to display, in the first region, a portion corresponding to a position of the first region out of the second image data, and display, in the second region, a portion corresponding to a position of the second region out of the third image data, the boundary line being displayed so as to be movable by a user operation, wherein
• the processor is configured to display, in the first region, a portion corresponding to the position of the first region out of the first image data, and display, in the second region, a portion corresponding to the position of the second region out of the third image data in a case where the first switching image is selected, and
• the processor is configured to display, in the first region, a portion corresponding to the position of the first region out of the second image data, and display, in the second region, a portion corresponding to the position of the second region out of the third image data in a case where the second switching image is selected after the first switching image is selected.
