Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A charged particle beam device for inspection of a specimen, comprising:
a specimen holder for holding a specimen;
a source for producing a beam of charged particles;
an illuminator for focusing said charged particle beam onto said specimen;
a detector for detecting a flux of radiation emanating from the specimen in response to said irradiation by said charged particle beam; and
a data processing apparatus coupled to at least the detector, and the data processing apparatus including code that, when executed by the data processing apparatus, causes the data processing apparatus to:
receive an image;
provide a set-point for a desired image quality parameter of said image;
process said image using an image analysis technique to determine a current image quality parameter of said image;
compare said current image quality parameter with said set-point, and generate, based on said comparison, a modified image based on an image modification technique, wherein to generate a modified image comprises:
improve said image in terms of said image quality parameter in case said current image quality parameter is lower than said set-point; and
deteriorate said image in terms of said image quality parameter in case said current image quality parameter exceeds said set-point; and

output and analyse said modified image, wherein said analysing comprises the step of using an artificial neural network (ANN) and/or a convolutional neural network (CNN) on said modified image.
