Title
(EN) COLOR MEASURING APPARATUS AND PROCESS ACHIEVEMENT DEGREE DETERMINATION APPARATUS
(FR) APPAREIL DE MESURE DE COULEUR ET APPAREIL DE DÉTERMINATION DE DEGRÉ DE RÉALISATION DE PROCESSUS
Abstract
(EN)
A determination apparatus (1) that determines an achievement degree of a predetermined process using a test paper (2) having a discoloration region whose color changes in accordance with the achievement degree of the predetermined process is provided. The determination apparatus (1) includes: measuring means (3) for measuring an optical characteristic value of a measurement region including the discoloration region of the test paper (2); holding means (9) for holding a determination information indicating a relationship between an area of the discoloration region in the measurement region and the optical characteristic value, for each of a plurality of achievement degrees of the predetermined process; and determining means (10) for determining the achievement degree of the predetermined process based on the optical characteristic value of the measurement region of the test paper measured by the measuring means, and the determination information.
(FR)
L'invention concerne un appareil de détermination (1) qui détermine un degré de réalisation d'un processus prédéterminé à l'aide d'un papier réactif (2) ayant une région de décoloration dont la couleur change en fonction du degré de réalisation du processus prédéterminé. L'appareil de détermination (1) comprend : des moyens de mesure (3) pour mesurer une valeur de caractéristique optique d'une région de mesure comprenant la région de décoloration du papier réactif (2) ; des moyens de conservation (9) pour conserver des informations de détermination indiquant une relation entre une zone de la région de décoloration dans la région de mesure et la valeur de caractéristique optique, pour chacun d'une pluralité de degrés de réalisation du processus prédéterminé ; et des moyens de détermination (10) pour déterminer le degré de réalisation du processus prédéterminé sur la base de la valeur de caractéristique optique de la région de mesure du papier réactif mesurée par les moyens de mesure, et des informations de détermination.
