Title:
IMAGE PROCESSING DEVICE, INFORMATION GENERATION DEVICE, AND INFORMATION GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/037678
Kind Code:
A1
Abstract:
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.
