Title: Image processing device, image processing method, and program
Inventor: HIRASAWA YASUTAKA
IPC: H04N5/232
Filed: 2021-05-13
Abstract: An identical-region detection unit detects, from multiple-polarization-direction polarization images acquired at a plurality of different viewpoints, identical regions to be processed for the respective viewpoints. The multiple-polarization-direction polarized images acquired for each of the plurality of different viewpoints are acquired by imaging over multiple frame periods during which the positional relationship between an object to be processed and a polarization image acquisition unit that acquires the polarization images changes. A degree-of-polarization calculation unit calculates the degree of polarization the identical region for each viewpoint on the basis of the multiple-polarization-direction polarization images. A reflection removal unit performs a reflection removal process on the identical regions to be processed, using the multiple-polarization-direction polarization image from the viewpoint at which the degree of polarization calculated by the polarization calculation unit is greatest. Thus, the reflection component can be removed even if the angle formed by the planar direction of the reflection surface and the imaging direction is not clear.
