DROPLET BEHAVIOR ANALYSIS METHOD AND DEVICE

PROBLEM TO BE SOLVED: To provide a method and a device enabling calculation of coordinate values to less than 1 pixel, using sub-pixel processing, and high-accuracy analysis of droplet behavior. SOLUTION: This droplet behavior analytical method/analyzer uses an algorithm capable of calculating the end point coordinates of a droplet to less than 1 pixel, by carrying out sub-pixel processing at the end point containing pixel, based on the concentration distributions of the end point containing pixel containing an end point of the droplet as an intersection of the droplet with a reference line, and the two pixels adjacent on the reference line to the end point containing pixel, or the plurality of pixels separated from the end point by a fixed distance, when photographing an image, including a large number of pixels to analyze the behavior of the droplet with respect to the reference line.
