Image capture devices configured to generate compensation gains based on an optimum light model and electronic apparatus having the same

摘要

An image capture device can include an analysis unit that can be configured to determine a refined light model that models a light source based on first and second image signals sampled with first and second exposure times, respectively, and corresponding to first and second rows of pixels. A compensation unit can be coupled to the analysis unit, and can be configured to generate an output image signal by compensating the first and second image signals and the second image signal using compensation gains associated with the refined light model.
