Titration system and program

Abstract

The present invention provides a titration system etc. capable of determining an equivalence point with high accuracy and having versatility. The titration system includes a camera installed so as to be able to photograph a flask containing a sample liquid, an image generating unit that generates image data representing an image of the sample liquid based on an image signal output from the camera, a storage unit that stores a plurality of parameter sets including a type of color value to be determined when determining the equivalence point and a judgment criterion corresponding to the type of color value, an operation input unit, a setting unit that reads out from the storage unit a parameter set corresponding to an input signal received by the operation input unit from the plurality of parameter sets and sets the type of color value to be determined and the judgment criterion based on the parameter set, a pixel value acquiring unit that acquires pixel values ​​in an area in the image where the sample liquid is captured, a color value acquiring unit that acquires color values ​​based on the pixel values ​​acquired by the pixel value acquiring unit, and a judging unit that evaluates the color value based on the judgment criterion.
