Liquid surface inspection device, automated analysis device, and processing device

An automatic analyzer comprising:

• a sample container transfer mechanism for transferring a sample container containing samples;
• a reagent container transfer mechanism for transferring a reagent container containing reagents to be mixed with the samples;
• a reaction container transfer mechanism for transferring a reaction container containing reaction liquids resulting from mixture of the samples and the reagents;
• an imaging mechanism for capturing images of the liquids contained in at least any of the sample container, the reagent container, and the reaction container;
• and
• a control device connected to the imaging mechanism and including a first liquid surface detector, a second liquid surface detector, and a mode selector, the first liquid surface detector detecting a condition of a liquid surface using color information contained in the image, the second liquid surface detector detecting a condition of the liquid surface by calculating a brightness gradient in a direction along an inner wall surface configuration of the container from the images, the mode selector selecting which of the first and second liquid surface detectors will be used.
