Abstract
Provided is a sample image observation device including an SEM and a control system configured to control the SEM. An observation region of a sample is divided into a plurality of sections, and restoration processing is performed on an image which is acquired by irradiating each section with a sparse electron beam, based on scanning characteristics in the section. A reduction in quality of a restored image due to a beam irradiation position deviation caused by a scanning response is prevented and restoration with high accuracy and high throughput under a condition for preventing sample damage is possible.
