Abstract
An apparatus that detects a cap attached to a container containing a specimen or a reagent, and includes: an imager that acquires an image of the container together with a pattern arranged in a background of the container; and a controller that decodes from the image a code attached to the container. The controller recognizes specific classified results including the pattern from the image, and detects the cap based on presence or absence of the specific classified results.
Claims6
An optical information reading apparatus comprising:
- an imager that acquires an image by imaging a container to which a code is attached and a pattern arranged in a background of the container;
- and
- a controller that decodes the code from the image and detects presence or absence of a cap of the container based on a state of the pattern in the image.
An optical information reading method, comprising:
- by an optical information reading apparatus,
- acquiring an image by imaging a container to which a code is attached and a pattern arranged in a background of the container;
- decoding the code from the image;
- and
- detecting presence or absence of a cap of the container based on a state of the pattern in the image.
An optical information reading program causing an optical information reading apparatus to execute:
- acquiring an image by imaging a container to which a code is attached and a pattern arranged in a background of the container;
- decoding the code from the image;
- and
- detecting presence or absence of a cap of the container based on a state of the pattern in the image.
