An automatic drug compounder system may be provided with various components and capabilities for reconstituting a drug in a vial and providing the reconstituted drug to a receiving container. The system may include a camera for capturing images of the vial and processing circuitry for extracting information such as a lot number and an expiration date from the images. The system may rotate the vial while capturing the images to capture images of the entire vial. The processing circuitry may search a portion of the image for the lot number and expiration date, the portion based on stored information. The stored information may include a location, orientation, font size, or font color for printed information for a particular vial. The stored information may be retrieved based on a bar code read by the system.
