Abstract
A particle measuring device includes: a detection unit that detects scattered light generated due to interaction between a particle contained in a liquid sample and light incident thereon, and converts the detected scattered light into a signal; an addition unit that performs a predetermined number of parallel processing on the signal to add the predetermined number of uncorrelated noises thereto and outputs the resulting signals; a binarization unit that binarizes the resulting signals using a binarization threshold set in accordance with the liquid sample, and outputs the binarized signals; a calculation unit that calculates and outputs a value based on the binarized signals; a filter unit that passes a predetermined frequency component of the output of the calculation unit; and a determination unit that determines that the particle is present when an output of the filter unit exceeds a predetermined particle threshold.
