Classification: CPC G  H | IPC G  H

Claim 0:
1. A scanning system, comprising:
an imaging line-scan camera; and
at least one hardware processor configured to execute computer-executable instructions to at least perform the process of:
acquiring image stripes of at least a portion of a sample on a glass slide by acquiring frames representing the image stripe using both the imaging line-scan camera and a tilted focusing line-scan camera;
adding focus points to a focus map representing positions of best focus of acquired frames to a focus map while acquiring the image stripe,
wherein the image stripes are acquired by acquiring a reference stripe extending along a scan axis, a position of the reference stripe corresponding to a region identified with a tissue-finding algorithm having the most tissue relative to other regions, acquiring image stripes in sequence from a first side of the reference stripe to a first edge of a scan area of the sample, and acquiring image stripes in sequence from a second side of the reference stripe, which is opposite the first side of the reference stripe, to a second edge of the scan area, which is opposite the first edge of the scan area, the acquired image stripes extending along the scan axis and offset relative to the reference stripe and each other image stripe along a separate stripe acquisition axis;
determining whether or not to re-acquire one or more of the image stripes based on the focus map; and
assembling the acquired image stripes into a composite image.
