PROBLEM TO BE SOLVED: To provide an abnormality detector that detects an abnormality accurately without the influence of a gas in a container.SOLUTION: An abnormality detector 1 comprises: a belt conveyor 10; a first camera 11; a second camera 12; and a control unit 13. The belt conveyor 10 serves as gas transfer means that changes an attitude of a container XA1 containing a liquid LIQ and a gas GAS and transfers the gas GAS. The first camera 11 captures an image of the container XA1 before the belt conveyor 10 transfers the gas GAS to obtain a first image PI1. The second camera 12 captures an image of the container XA1 after the belt conveyor 10 transfers the gas GAS to obtain a second image PI2. An image analyzing section 25 of the control unit 13 analyzes the first image PI1 and the second image PI2, determines that the difference between the first image PI1 and the second image PI2 is caused by the gas GAS, excludes the difference, and detects an abnormality. |
