METHOD AND IMAGE CAPTURING APPARATUS FOR MINIMIZING ERROR IN AMBIENT LIGHT CORRECTED IMAGE

According to one aspect, there is provided a method for minimizing motion-induced errors in an ambient light corrected image, the method comprising capturing a plurality of primary images having a controlled illumination intensity that varies over time, estimating a motion-induced error value for each subset of a plurality of subsets of the plurality of primary images, and outputting the motion-induced error value for each subset of the plurality of primary images. And performing ambient light correction on the error minimized subset of the main image having the lowest estimated error value to generate an ambient light corrected (ALC) image having a minimized error. Estimating an error value for each subset of the plurality of main images includes identifying a pair of main images in a subset including a first main image and a second main image, where the first main image is captured in time prior to the second main image, determining a displacement vector matrix between the pair of main images, and estimatin
