Patent attributes
In aspects of digital image capture with a polarizer at different rotation angles, a device includes a polarizer that filters light at different polarizations and captures digital images using the polarizer. Each of the digital images are captured at one of different rotation angles of the polarizer. The device implements an imaging algorithm to determine a common region in each of the digital images, the common region having a variable brightness in each of the digital images and the common region in a respective digital image being determined based on a standard deviation of brightness for each pixel in the respective digital image. The imaging algorithm can then determine pixel brightness values of the pixels in the common region for each of the digital images, and select one of the captured digital images with a lowest pixel brightness value in the common region as an output image.
