Abstract
According to various embodiments, there may be provided a method for determining an abnormality in image acquisition equipment, which includes: acquiring one or more 2-dimensional (2D) images by imaging a specific region; acquiring at least one of an average brightness value, a signal to noise ratio (SNR) value and a contrast to noise ratio (CNR) value for the one or more acquired 2-dimensional images; and determining whether the image acquisition equipment is abnormal based on the at least one of the acquired average brightness value, SNR value and CNR value, and a device therefor.

A method for determining an abnormality in image acquisition equipment, the method comprising:
- acquiring one or more 2-dimensional (2D) images by imaging a specific region;
- acquiring at least one of an average brightness value, a signal to noise ratio (SNR) value and a contrast to noise ratio (CNR) value for the one or more acquired 2-dimensional images;
- and
- determining whether the image acquisition equipment is abnormal based on the at least one of the acquired average brightness value, SNR value and CNR value
- wherein the one or more acquired 2-dimensional images comprise at least some of images captured with a sample being placed in the specific region, and images captured with the sample being placed so as not to be overlapped with at least a portion of a specimen when the specimen is placed in the specific region, and
- the CNR value is acquired based on the sample in each of the one or more 2-dimensional images.
A device for determining an abnormality in image acquisition equipment, the device comprising:
- an image acquisition unit configured to acquire one or more 2-dimensional images by imaging a specific region;
- and
- a performance determination unit configured to acquire at least one of an average brightness value, a signal to noise ratio (SNR) value and a contrast to noise ratio (CNR) value for the one or more acquired 2-dimensional images, and determine whether the image acquisition equipment is abnormal based on the at least one of the acquired average brightness value, SNR value and CNR value
- wherein the one or more acquired 2-dimensional images comprise at least some of images captured with a sample being placed in the specific region, and images captured with the sample being placed so as not to be overlapped with at least a portion of a specimen when the specimen is placed in the specific region, and
- the performance determination unit acquires the CNR value based on the sample in each of the one or more 2-dimensional images.
