1. A method comprising: receiving multiple sequential images captured by an image capture device, wherein the multiple sequential images comprise images that are aligned to each other and images that are not aligned to each other; selecting a subset of the multiple sequential images that are determined to be aligned to each other based on a stationary region of interest detected in the multiple sequential images, from the images that are aligned to each other and images that are not aligned to each other, wherein selecting the subset of the multiple sequential images based on the stationary region of interest comprises calculating a sum of absolute differences of pixel values between respective images in at least one channel for pixels in the stationary region of interest; and averaging pixel values from each image in the subset of the multiple sequential images to produce a combined image.
