1. A report format setup apparatus connecting to a defect observation apparatus that acquires a plurality of images of defects on a sample, comprising: a display configured to display a module selector to select one of a plurality of modules that represent corresponding components of a result of observation of the sample and configured to display an output format setup area to arrange the modules; a pointing device configured to arrange each module in a position on the output format setup area; and a template creation manager configured to generate a report format in which the component of the result observation corresponding to each module is arranged in a position corresponding to the position of each module on the output format setup area, wherein the template creation manager is further configured to generate, when the report format includes at least a wafer map representing a spatial distribution of the defects on a wafer, a plurality of positions of the defects and the plurality of images of the defects, the report format for displaying a relation between each of the plurality of defect images and a corresponding one of the plurality of defect positions represented by the wafer map.
