Abstract: There is provided an eyeball observation device, which can stably detect a line of sight, the eyeball observation device including: at least one infrared light source configured to radiate polarized infrared light onto an eyeball of a user; and at least one imaging device configured to capture an image of the eyeball irradiated with the polarized infrared light and to be capable of simultaneously capturing a polarization image with at least three directions.

Abstract: An imaging unit 20 has a configuration in which an identical polarization pixel block made up of a plurality of pixels with an identical polarization direction is provided for each of a plurality of polarization directions and pixels of respective predetermined colors are provided in the identical polarization pixel block. A correction processing unit 31 performs correction processing such as white balance correction on a polarized image generated by the imaging unit 20. A polarized image processing unit 32 separates or extracts a reflection component using the polarized image after the correction processing. By using a polarized image of the separated or extracted reflection component, for example, it is possible to generate normal line information with high accuracy.
