There is provided an analyzer apparatus capable of generating crisp scanned images. In the analyzer apparatus, a sample is scanned with a probe such that a first signal and a second signal are emitted from the sample. The analyzer apparatus comprises: a first detector for detecting the first signal and producing a first detector signal; a second detector for detecting the second signal and producing a second detector signal; and an image processing unit operating (i) to produce a first scanned image and a second scanned image from the first detector signal and the second detector signal, respectively, (ii) to create a filter based on the second scanned image having a higher signal-to-noise ratio than that of the first scanned image, and (iii) to apply the filter to the first scanned image.
