Title:
撮像装置およびその制御方法、プログラム
Document Type and Number:
Japanese Patent JP7446804
Kind Code:
B2
Abstract:
An electronic device acquires polarization information of a subject based on a plurality of pieces of image data based on a first signal output from a first sensor. The first sensor can capture an optical image of the subject acquired via a polarizing filter provided with areas having different polarization angles. The device further acquires an evaluation value for controlling brightness of an image at the time of capturing the optical image of the subject, based on the plurality of pieces of image data. The plurality of pieces of image data have different polarization angles, by respectively being acquired via areas of the polarizing filter having the plurality of different polarization angles. A degree of weighting to be assigned to the plurality of pieces of image data at the time of acquiring the evaluation value based on the polarization information.
