Abstract:
(EN) A correction information generation unit 50 irradiates a polarized image acquisition unit 20 for acquiring a polarized image with measurement light having uniform intensity. On the basis of a measurement polarized image acquired from the polarized image acquisition unit 20, the correction information generation unit 50 generates variation correction information for correcting sensitivity variation occurring in the measurement polarized image due to a difference in polarization direction, and stores the variation correction information in a correction information storage unit 30. A correction processing unit 40 uses the variation correction information previously generated and stored in the correction information storage unit 30 to correct sensitivity variation occurring due to a difference in polarization direction in the polarized image acquired thereafter by the polarized image acquisition unit 20. Consequently, it is possible to make the polarized image outputted from the correction processing unit 40 a high-quality polarized image in which sensitivity variation and the like are corrected.
(FR) Selon l'invention, une unité de génération d'informations de correction 50 irradie une unité d'acquisition d'image polarisée 20 pour acquérir une image polarisée avec une lumière de mesurage dont l'intensité est uniforme. Sur la base d'une image polarisée de mesurage acquise à partir de l'unité d'acquisition d'image polarisée 20, l'unité de génération d'informations de correction 50 génère des informations de correction de variation pour corriger une variation de sensibilité se produisant dans l'image polarisée de mesurage en raison d'une différence de la direction de polarisation, et stocke les informations de correction de variation dans une unité de stockage d'informations de correction 30. Une unité de traitement de correction 40 utilise les informations de correction de variation préalablement générées et stockées dans l'unité de stockage d'informations de correction 30 pour corriger une variation de sensibilité se produisant en raison d'une différence de la direction de polarisation dans l'image polarisée acquise par la suite par l'unité d'acquisition d'image polarisée 20. L'invention fait ainsi de l'image polarisée émise à partir de l'unité de traitement de correction 40 une image polarisée de haute qualité dans laquelle une variation de sensibilité et similaire sont corrigées.
(JA) 補正情報生成部50は、偏光画像を取得する偏光画像取得部20に強度が一様の計測光を照射する。また、補正情報生成部50は、偏光画像取得部20から取得した計測偏光画像に基づき、この計測偏光画像に生じた偏光方向の違いによる感度ばらつきを補正するばらつき補正情報を生成して補正情報記憶部30に記憶させる。補正処理部40は、予め生成されて補正情報記憶部30に記憶されているばらつき補正情報を用いて、その後、偏光画像取得部20で取得された偏光画像に対して、偏光方向の違いによって生じた感度ばらつきを補正する。このため、補正処理部40から出力される偏光画像を、感度ばらつき等が補正された高画質の偏光画像にできる。
