To shorten a time required for evaluation of a recipe while suppressing an increase in a data amount. A charged particle beam device includes a microscope that scans a charged particle beam on a sample, detects secondary particles emitted from the sample, and outputs a detection signal and a computer system that generates a frame image based on the detection signal and processes an image based on the frame images. The computer system calculates a moment image between a plurality of the frame images, and calculates a feature amount data of the frame image based on a moment.

The purpose of the present invention is to provide a pattern measurement device for quantitatively evaluating a pattern formed using a directed self-assembly (DSA) method with high accuracy. The present invention is a pattern measurement device for measuring distances between patterns formed in a sample, wherein the centroids of a plurality of patterns included in an image are determined; the inter-centroid distances, and the like, of the plurality of centroids are determined; and on the basis of the inter-centroid distances, and the like, of the plurality of centroids, a pattern meeting a specific condition is distinguished from patterns different from the pattern meeting the specific condition or information is calculated about the number of the patterns meeting the specific condition, the size of an area including the patterns meeting the specific condition, and the number of imaginary lines between the patterns meeting the specific condition.
