Automatic Analyzer

An automatic analyzer comprising:

• a dispensing probe configured to dispense a predetermined amount of liquid;
• a reaction vessel to which the liquid is dispensed from the dispensing probe;
• an analysis mechanism configured to analyze a component of the liquid in the reaction vessel;
• a dispensing detection unit configured to detect a contact state between the reaction vessel and the liquid dispensed into the reaction vessel from the dispensing probe;
• an imaging device configured to capture images of the contact state;
• an image processing unit configured to select an image for determining an amount of the liquid dispensed into the reaction vessel from the images captured by the imaging device based on information from the dispensing detection unit and extract a feature of the liquid from the selected image;
• a storage unit configured to store a database in which the feature of the liquid and information on a component amount of the liquid analyzed by the analysis mechanism are associated with each other;
• and
• a liquid amount calculation unit configured to calculate the amount of the liquid dispensed by the dispensing mechanism from the extracted feature based on the database stored in the storage unit.
