ANALYSIS METHOD AND ANALYSIS DEVICE

An analysis device is provided which can exclude the influence of impurities during measurement and to acquire an accurate brightness value of a measurement target while avoiding costs from increasing and work processes from becoming complex. This analysis device 100, which is for analyzing samples, is provided with a light source 101, an imaging unit 103 which condenses transmitted light, receives the light intensity and acquires the brightness value, and a control unit 105. The analysis device 100 is provided with multiple reference samples 108 which differ in transmittance and color, and a storage unit 104 which stores the brightness values, and a control value of the light source 101. The control unit 105 irradiates the reference sample 108 with light at a set control value, and stores, in the storage unit 104, an acquired measured brightness value of the reference sample, and an adjustment control value of the light source 101 for adjusting to a set reference brightness value; from the brightness value of a sample to be measured, which was acquired by irradiating the sample 106 to be measured with light on the basis of the control value, the control unit 105 calculates an adjustment control value of the light source 101 on the basis of the relation between the adjustment control value of the light source 101 and the brightness value of the sample 106 to be measured, and uses the adjustment control value to irradiate light and, with the imaging unit 103, acquires the brightness value of the sample 106 to be measured. L'invention concerne un dispositif d'analyse qui peut exclure l'influence d'impuretés pendant la mesure et permettre d'acquérir une valeur de luminosité précise d'une cible de mesure tout en évitant la complexité des coûts des processus d'augmentation et de travail. Ce dispositif d'analyse 100, destiné à analyser des échantillons, est pourvu d'une source de lumière 101, d'une unité d'imagerie 103 qui condense la lumière transmise, reçoit l'intensité de lumière et acquiert la valeur de luminosité, et d'une unité de commande 105. Le dispositif d'analyse 100 est pourvu de plusieurs échantillons de référence 108 qui diffèrent en matière de transmittance et de couleur, et d'une unité de stockage 104 qui stocke les valeurs de luminosité, et une valeur de commande de la source de lumière 101. L'unité de commande 105 irradie l'échantillon de référence 108 de lumière selon une valeur de commande définie, et stocke, dans l'unité de stockage 104, une
